ALFALFA (Alfalfa Fat-Soluble Extract)

INSUFFICIENT RELIABLE EVIDENCE to RATE

Diabetes. Although there has been interest in using oral alfalfa for diabetes, there is insufficient reliable information about the clinical effects of alfalfa for this purpose.
Dyspepsia. Although there has been interest in using oral alfalfa for dyspepsia, there is insufficient reliable information about the clinical effects of alfalfa for this purpose.
Hypercholesterolemia. It is unclear if oral alfalfa seeds are beneficial in patients with hypercholesterolemia. Details: A small, uncontrolled clinical study in patients with hypercholesterolemia shows that taking heat-prepared alfalfa seeds 40 grams three times daily for 8 weeks reduces total cholesterol and low-density lipoprotein (LDL) cholesterol levels when compared to baseline (5816). The validity of these findings is limited by the lack of a control group.
Menopausal symptoms. Although there has been interest in using oral alfalfa for menopausal symptoms, there is insufficient reliable information about the clinical effects of alfalfa for this purpose. There is insufficient reliable information available about the effectiveness of alfalfa for its other uses.

BUCKWHEAT (organic Buckwheat)

INSUFFICIENT RELIABLE EVIDENCE to RATE

Cardiovascular disease (CVD). A meta-analysis of clinical research shows that taking buckwheat seems to improve some, but not all, markers of CVD risk. Buckwheat was found to decrease total cholesterol by 19 mg/dL, triglycerides by 22 mg/dL, and blood glucose by 15 mg/dL, but had no effect on blood pressure, body weight, insulin, or low-density lipoprotein (LDL) cholesterol when compared with a control group (100947). The patient populations included in this analysis ranged from healthy adults to those with diabetes or hyperlipidemia; it's unclear whether the results are consistent across patient groups or if the benefits are more pronounced in certain types of patients. The effects of buckwheat on cardiovascular events, such as myocardial infarction, stroke, or cardiovascular death, in patients with CVD, are unknown.
Chronic venous insufficiency (CVI). Preliminary clinical research shows that drinking common buckwheat tea for 3 months attenuates leg swelling compared with placebo in patients with chronic venous insufficiency (37351).
Diabetes. Preliminary clinical research shows that patients with type 2 diabetes who replace a portion of white rice or white flour with tartary buckwheat 50 grams three times daily for 4 weeks show a 3% reduction in fasting insulin and a 7% reduction in low-density lipoprotein (LDL) cholesterol compared to baseline. Patients who consume the standardized recipe containing white rice and/or white flour three times daily for 4 weeks show no significant changes in these measurements. Neither groups show improvement in fasting blood glucose or hemoglobin A1c levels (96063).
Diabetic retinopathy. Preliminary clinical research shows that taking common buckwheat 1 gram three times daily for 3 months does not significantly improve visual acuity compared with baseline in patients with diabetic retinopathy (37358). More evidence is needed to rate the effectiveness of buckwheat for these uses.

CARROT (organic Carrot)

POSSIBLY EFFECTIVE

Vitamin A deficiency. Some preliminary clinical research shows that consuming one spoonful of carrot jam daily for 10 weeks improves growth velocity when compared with control in children with vitamin A deficiency (25819). Other preliminary research shows that consuming 100 grams of grated carrot daily for 60 days improves vitamin A status when compared with placebo in lactating women at risk for vitamin A deficiency (67861).

INSUFFICIENT RELIABLE EVIDENCE to RATE

Breast cancer. A meta-analysis of observational research has found that consuming a diet highest in carrots is associated with a 21% decreased odds of developing breast cancer when compared with consuming a diet lowest in carrots (101715).
Colorectal cancer. A large observational study in older Danish adults shows that self-reported high consumption of raw carrot (2-4 carrots weekly or greater than 32 grams daily) is associated with a 17% lower likelihood of colorectal cancer diagnosis, whereas lower carrot consumption is not associated with a decreased risk. The validity of these findings may be limited by selection bias, recall bias, and other confounding factors (106559).
Fibromyalgia. Preliminary clinical research shows that consuming a mostly raw, pure vegetarian diet that includes two to four 240 mL servings of carrot juice daily for 7 months might improve fibromyalgia symptoms in some people (98057). The effect of carrot alone on fibromyalgia is unknown.
Prostate cancer. Population research has found that higher intake of carrot is associated with an 18% decrease in the odds of developing prostate cancer. Increasing carrot consumption by 10 grams daily or 1 serving per week is associated with a 4% to 5% decrease in the odds of developing prostate cancer (96307). More evidence is needed to rate carrot for these uses.

LECITHIN (Sunflower Lecithin)

LIKELY INEFFECTIVE

Alzheimer disease. Lecithin does not improve daily functioning in patients with Alzheimer disease. Details: In patients with Alzheimer disease, taking various types of lecithin, 1.2-45 grams daily for up to 6 months, alone or in combination with various conventional medications, does not improve cognitive function or other measures of disease progression (5149,5151,5152,5156,14817,14823,14825,14837,14838).

INSUFFICIENT RELIABLE EVIDENCE to RATE

Age-related cognitive decline. It is unclear if oral lecithin can slow age-related cognitive decline. Details: A small clinical crossover study in healthy adults aged 64 years and older shows that taking lecithin 26 grams orally daily, alone or in combination with physostigmine, for 5 weeks does not seem to improve memory when compared with placebo (19204).
Anxiety. Although there is interest in using oral lecithin for anxiety, there is insufficient reliable information about the clinical effects of lecithin for this condition.
Atopic dermatitis (eczema). Although there is interest in using oral lecithin for atopic dermatitis, there is insufficient reliable information about the clinical effects of lecithin for this condition.
Bipolar disorder. It is unclear if oral lecithin is beneficial in patients with bipolar disorder. Details: A clinical study in six patients with mania shows that taking lecithin 10 mg three times daily improves symptoms of delusions, incoherent speech, and hallucinations when compared with placebo (14839).
Dry skin. Although there is interest in using topical lecithin for dry skin, there is insufficient reliable information about the clinical effects of lecithin for this condition.
Friedreich ataxia. Small clinical studies suggest that oral lecithin is not beneficial in people with Friedreich ataxia. Details: Preliminary clinical research shows that taking lecithin 25 grams orally daily for 1 month does not have any benefit in people with Friedreich ataxia (59298). Other preliminary clinical research shows that taking lecithin for a longer period of 6 months also does not improve performance (19211).
Hyperlipidemia. Although lecithin may lower cholesterol in healthy people, it does not seem to improve cholesterol levels in people with hyperlipidemia. Details: Some clinical research shows that taking lecithin 20-30 grams daily for up to 11 months decreases cholesterol in healthy people (5147,14820). However, other clinical research shows that lecithin has no effect on low-density lipoprotein cholesterol or total cholesterol levels in people with hyperlipidemia (5148,14820).
Parkinson disease. It is unclear if oral lecithin is beneficial in patients with Parkinson disease. Details: Preliminary clinical research in patients with Parkinson disease shows that taking lecithin 32 grams daily for 8 weeks does not improve symptoms when compared with placebo (19212).
Postoperative pain. It is unclear if oral lecithin is beneficial for reducing postoperative pain. Details: Preliminary clinical research shows that taking lecithin 20 grams prior to surgery increases choline levels, but does not reduce postoperative pain after gynecological surgery, when compared with placebo (91231).
Tardive dyskinesia. It is unclear if oral lecithin is beneficial in patients with tardive dyskinesia. Details: Two small clinical studies in patients with tardive dyskinesia shows that taking lecithin orally for 2 months, alone or in combination with lithium, does not improve symptoms when compared with placebo (14822,14824).
TPN-associated hepatic steatosis. It is unclear if oral lecithin is beneficial in patients with hepatic steatosis associated with long-term total parenteral nutrition (TPN). Details: A small clinical study in patients on long-term TPN with low choline levels suggests that taking lecithin 20 grams orally twice daily for 6 weeks reduces the degree of hepatic steatosis, compared with no significant changes in those taking placebo (5140).
Ulcerative colitis. Oral lecithin has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: Preliminary clinical research shows that taking a disease-specific medical food (Profermin, Nordisk Rebalance) containing lecithin, fermented oats, barley malt, and lactobacillus plantarum, as 250 mL twice daily for 24 weeks, decreases disease activity by over 56% when compared with baseline and leads to remission in 46% of patients with mild-to-moderate ulcerative colitis (91228). Other preliminary clinical research in this population shows that taking Profermin 250 mL twice daily for 8 weeks improves disease activity and remission rate when compared with another medical food (Fresubin Original, Fresenius Kabi) (90271). The effects of lecithin alone are unclear. More evidence is needed to rate lecithin for these uses.

SESAME (organic Sesame seed Oil)

POSSIBLY EFFECTIVE

Hypertension. Oral sesame oil seems to reduce blood pressure by a small amount. Details: Meta-analyses of clinical research involving patients with or without hypertension show that taking sesame, or the sesame constituent sesamin, can reduce both systolic blood pressure (SBP) and diastolic blood pressure (DBP) (96179,108355,108357). One meta-analysis of eight clinical studies shows that sesame or sesamin can reduce SBP by 8 mmHg and DBP by 6 mmHg when compared with control. In a subgroup analysis of patients with hypertension, reductions in SBP and DBP were 11 mmHg and 9 mmHg, respectively. In a subgroup analysis by formulation, sesame oil was shown to reduce SBP and DBP by 13 mmHg and 10 mmHg, respectively, while whole sesame seed, ground seed, or sesame supplement lowered SBP by only 3 mmHg and did not lower DBP (96179). Another meta-analysis of clinical studies involving patients with hypertension, metabolic syndrome, or kidney failure shows that taking sesame oil reduces SBP and DBP by 3 mmHg and 2 mmHg, respectively, although benefits were limited to studies of less than 8 weeks (108355). Some research on sesame oil involved replacing other cooking oils with a specific brand of sesame oil (Idhayam Gingelly oil, V.V.V. & Sons) 35 grams daily for about 6-9 weeks. Patients included in these studies were also using atenolol, nifedipine, and/or hydrochlorothiazide as antihypertensives (27652,27654,27655). Other preliminary clinical research shows that using a 20:80 blend of sesame oil and rice bran oil (Vivo, Adani Wilmar) as cooking oil for 8 weeks improves blood pressure and lipid profile in patients with hypertension. In patients using nifedipine, using the oil blend seems to reduce systolic and diastolic blood pressure by an additional 2 to 2.2-fold over nifedipine alone (96180).

POSSIBLY INEFFECTIVE

Cough. Oral sesame oil does not seem to be beneficial for cough in children. Details: Clinical research in children with an acute cough due to common cold shows that taking sesame oil 5 mL by mouth at bedtime for 3 consecutive days does not reduce cough strength or cough frequency when compared with placebo (27647).

INSUFFICIENT RELIABLE EVIDENCE to RATE

Aging skin. Although there is interest in using topical sesame oil for aging skin, there is insufficient reliable information about the clinical effects of sesame for this purpose.
Alzheimer disease. Although there is interest in using oral sesame for Alzheimer disease, there is insufficient reliable information about the clinical effects of sesame for this condition.
Anemia of chronic disease. Although there is interest in using oral sesame for anemia of chronic disease, there is insufficient reliable information about the clinical effects of sesame for this condition.
Anxiety. Although there is interest in using topical sesame oil for anxiety, there is insufficient reliable information about the clinical effects of sesame for this purpose.
Bowel obstruction. It is unclear if oral sesame oil is beneficial for bowel obstruction. Details: Preliminary clinical research in adults with adhesive small bowel obstruction shows that giving sesame oil 150 mL through a nasogastric tube along with standard treatment reduces the need for surgical intervention when compared with standard treatment alone. Also, the resolution time of the obstruction was 6 hours faster and the duration of hospitalization was 4 days shorter for patients treated with sesame oil plus standard treatment when compared with standard treatment alone (27645). Standard treatment consisted of stopping oral intake of food, performing nasogastric tube decompression, administering intravenous fluids with electrolytes, and providing parenteral antibiotics if leukocytosis was present.
Burns. It is unclear if topical sesame oil is beneficial for burns. Details: Preliminary clinical research in adults and children with partial thickness thermal burns covering less than 40% of body surface area shows that topical application with a moist exposed burn ointment (MEBO) containing sesame oil, beta-sitosterol, berberine, and other unspecified plant ingredients every 4 hours reduces the median time to 75% healing by 3 days (17 days vs. 20 days) and improves analgesic effects during the first 5 days of treatment when compared with a control group receiving cleansing with chlorhexidine 0.05%. The MEBO was left on the burn for 5 days, followed by removal and reapplication at 4 hourly intervals on day 5, to be left on until day 14 (13526).
Cardiovascular disease (CVD). Although there is interest in using oral sesame for CVD, there is insufficient reliable information about the clinical effects of sesame for this condition.
Cataracts. Although there is interest in using oral sesame for cataracts, there is insufficient reliable information about the clinical effects of sesame for this condition.
Chemotherapy-induced phlebitis. It is unclear if massage with topical sesame oil is beneficial for chemotherapy-induced phlebitis. Details: Preliminary clinical research in patients with colorectal cancer and chemotherapy-induced phlebitis shows that applying 10 drops of sesame oil within a 10 cm radius of the affected veins as part of a 5-minute, twice-daily massage reduces pain after 7 days when compared with massage alone (103227).
Child growth. It is unclear if massage with topical sesame oil is beneficial for child growth. Details: Preliminary clinical research in full-term healthy infants shows that administering a daily massage with sesame oil 20 mL for 4 weeks improves infant length by 1 cm, midarm circumference by 0.9 cm, and midleg circumference by 0.7 cm when compared with a control group that did not receive a massage (29722). It is unclear if these effects are due to sesame oil, massage, or the combination.
Cognitive impairment. It is unclear if oral sesame is beneficial for cognitive impairment. Details: Clinical research in older adults with memory impairment shows that taking sesame oil cake extract (Keukdong H-Pharm Co., Ltd.) 500 mg three times daily for 12 weeks modestly improves some, but not all, measures of cognitive function when compared with placebo (108351). In addition, preliminary clinical research in patients with mild cognitive impairment shows that taking two capsules of a combination product containing the sesame constituent sesamin 5 mg and astaxanthin 3 mg daily for 12 weeks increases psychomotor and processing speed when compared with placebo. However, there was no effect on memory, attention, or overall severity of cognitive symptoms (99863). It is not clear if these effects are due to sesamin, astaxanthin, or the combination.
Dental plaque. It is unclear if rinsing the mouth with sesame oil or pulling the oil through the teeth is beneficial for dental plaque. Details: Preliminary clinical research in children 12-14 years of age shows that rinsing with 10 mL of ozonated or non-ozonated sesame oil for 10 minutes daily for 15 days reduces plaque when compared with baseline. The ozonated sesame oil was superior to non-ozonated sesame oil, showing a similar improvement in plaque when compared with chlorhexidine mouthwash (103226). A small clinical study in healthy adults shows that pulling sesame oil 10 mL through the teeth for 15-20 minutes twice daily for 4 days has similar effects on full-mouth prevention of plaque regrowth, tooth staining, gingival index, and bleeding when compared with pulling coconut oil through the teeth (106038).
Diabetes. It is unclear if oral sesame oil is beneficial for diabetes. Details: Meta-analyses suggest that taking sesame for 6-12 weeks modestly reduces levels of fasting blood glucose and glycated hemoglobin (HbA1c), but not insulin levels or insulin resistance, when compared with placebo, baseline, or other control. Sesame oil and seed flour, tahini, and sesamin were used in the included research (108350,108352,108355). Although most studies included in these meta-analyses were conducted in patients with type 2 diabetes, one study (103231) was conducted in patients with metabolic syndrome. One small clinical trial included in these meta-analyses shows that replacing other cooking oils with a specific brand of sesame oil (Idhayam Gingelly oil, V.V.V. & Sons) 35 grams daily for 45 days reduces blood glucose levels and HbA1c when compared with baseline in patients with diabetes who are also using glibenclamide (27654). Sesame oil has also been investigated in combination with rice bran oil. One preliminary clinical trial in patients with type 2 diabetes not using antidiabetes medications shows that using a specific 20:80 blend of sesame oil and rice bran oil (Vivo, Adani Wilmar) as the only cooking oil for 8 weeks reduces levels of fasting blood glucose by 14% and reduces HbA1c when compared with baseline. In patients taking glibenclamide 5 mg daily, using this oil blend reduces fasting blood glucose and HbA1c when compared with glibenclamide alone (96177). The use of sesame oil has also been investigated for improving cardiometabolic markers in patients with type 2 diabetes. Clinical research in adults taking antidiabetes medications shows that replacing regular dietary oils with sesame oil or a blend of sesame and canola oils for 9 weeks does not improve most cardiometabolic markers when compared with canola oil or sunflower oil as a control (108353).
Gastric cancer. Although there is interest in using oral sesame for gastric cancer prevention, there is insufficient reliable information about the clinical effects of sesame for this purpose.
Gingivitis. It is unclear if pulling sesame oil through the teeth is beneficial for gingivitis. Details: Preliminary clinical research in adolescent males with plaque-induced gingivitis shows that oil pulling with sesame oil for one minute daily each morning prior to brushing for 10 days reduces dental plaque and gingivitis when compared with baseline (27648). The validity of this finding is limited by the lack of a comparator group.
Hemorrhoids. Topical sesame oil has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: A small study in adults with symptomatic mild to moderate (first- and second-degree) internal hemorrhoids shows that application of a cream containing sesame oil and aqueous extracts of guggul and Allium ampeloprasum as a thin layer to the anus twice daily for 3 weeks improves anal irritation and itching, bleeding, pain, defecation discomfort, and swelling sense when compared with baseline. In contrast, patients using a placebo cream experienced an improvement only in anal itching (105751). The poor study methodology and lack of statistical comparison to the placebo group limit the validity of these findings.
HIV/AIDS-related wasting. Oral sesame has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: Preliminary clinical research in adults with HIV shows that consuming 300 grams of a chickpea and sesame-based food supplement daily for 3 months, along with routine sulfamethoxazole-trimethoprim, improves weight gain, body mass index, and mid-upper arm circumference in 73% of patients, and results in improved physical performance in 78% of patients, when compared to baseline (27657). The validity of these findings is limited by the lack of a comparator group.
Hyperlipidemia. It is unclear if oral sesame is beneficial for hyperlipidemia. Details: A meta-analysis of a limited number of clinical studies that included mainly patients without hyperlipidemia shows that consuming sesame 25-50 grams daily or using sesame oil 3.5-35 grams daily for up to 10 weeks does not reduce levels of total or low-density lipoprotein (LDL) cholesterol when compared with baseline (96181). However, a more recent meta-analysis with similar studies shows that consuming sesame reduces levels of total cholesterol by 16 mg/dL, although there is no effect on levels of LDL cholesterol or high-density lipoprotein (HDL) cholesterol (108357). Both analyses show that taking sesame reduces triglyceride levels by about 21 mg/dL (96181,108357). Significant heterogeneity of the included studies and patient populations limits the validity of these results.
Insect repellent. Although there is interest in using topical sesame oil as an insect repellent, there is insufficient reliable information about the clinical effects of sesame for this purpose.
Male infertility. It is unclear if oral sesame is beneficial for male infertility. Details: Preliminary clinical research in males with infertility shows that taking sesame 0.5 mg/kg daily for 3 months modestly improves sperm count and motility, but not sperm morphology, when compared with baseline (108356). The validity of these findings is limited by the lack of a comparator group.
Menopausal symptoms. Although there is interest in using oral sesame for menopausal symptoms, there is insufficient reliable information about the clinical effects of sesame for this purpose.
Metabolic syndrome. It is unclear if oral sesame oil is beneficial for improving metabolic parameters in adults with metabolic syndrome. Details: Preliminary clinical research in patients with metabolic syndrome shows that taking sesame oil 30 mL with or without vitamin E 400 mg daily for 8 weeks improves levels of fasting blood glucose, lipids, and blood pressure when compared with sunflower oil. In those taking sesame oil alone, total cholesterol and triglycerides were reduced by about 13 mg/dL, while low-density lipoprotein (LDL) cholesterol and high-density lipoprotein (HDL) cholesterol were not affected. In those also taking sesame oil with vitamin E, total cholesterol and triglycerides were reduced by 17 mg/dL and 21 mg/dL, respectively, while HDL cholesterol was increased by 4 mg/dL. Additionally, systolic and diastolic blood pressure were reduced by 10 mmHg and 8 mmHg, respectively, in those taking sesame oil alone, versus 15 mmHg and 9 mmHg, respectively, in those taking sesame oil with vitamin E (103231).
Miscarriage. It is unclear if oral sesame is beneficial for the management of an incomplete miscarriage. Details: Preliminary clinical research in patients with incomplete abortion related to miscarriage shows that taking sesame seed twice daily for 5 days results in complete resolution of retained products of conception in 84% of individuals, based on a sonographic assessment, compared with 26% of those receiving expectant management as control. There was also a 2-day reduction in the duration of vaginal bleeding when compared with control. Each dose of ground sesame seed powder 30 grams was boiled in 200 mL water for 4 minutes and then filtered before drinking (108346).
Nonalcoholic fatty liver disease (NAFLD). It is unclear if oral sesame oil is beneficial for NAFLD. Details: Clinical research in females with NAFLD shows that taking sesame oil 30 grams daily for 12 weeks reduces the severity of fatty liver in 89% of patients taking sesame oil, compared with 58% of those taking sunflower oil. There were also modest reductions in levels of aspartate aminotransferase (AST) and alanine aminotransferase (ALT), but not alkaline phosphatase (ALP), when compared with sunflower oil. All patients were also consuming a 500-kcal hypocaloric diet (108354).
Obesity. It is unclear if oral sesame is beneficial for weight loss. Details: Meta-analyses of clinical research show that taking sesame or sesame oil in doses of at least 35 grams daily reduces body weight by up to 2 kg and body mass index by up to 1 kg/m² when compared with no oil or a control oil. Clinical studies included in these meta-analysis enrolled patients with type 2 diabetes, hypertension, hypercholesterolemia, and others, and were not limited to overweight or obese individuals (108355,108357). A small clinical study in overweight individuals shows that replacing regular dietary oil with sesame oil for 9 weeks does not improve levels of most cardiometabolic risk factors, although there were modest beneficial effects on insulin (108349).
Osteoarthritis. It is unclear if topical sesame oil is beneficial for knee osteoarthritis. Details: Preliminary clinical research in patients with osteoarthritis of the knee shows that applying sesame oil 1.5 mL to the affected knee three times daily for 4 weeks reduces pain and improves physical function when compared to baseline. These improvements were similar to those seen in patients applying diclofenac topical gel (103228).
Osteoporosis. Although there is interest in using oral sesame for osteoporosis, there is insufficient reliable information about the clinical effects of sesame for this condition.
Pain (acute). It is unclear if massage with topical sesame oil is beneficial for acute pain caused by blunt trauma. Details: One small clinical study shows that using a specific sesame oil (Saman sesame oil, Saman sesame oil Co.) topically as part of a light massage for 5 minutes twice daily for 9 days moderately reduces acute pain caused by blunt trauma to an extremity by day 6 when compared with a light massage with placebo oil. However, the sesame oil massage does not reduce the use of nonsteroidal anti-inflammatory drugs when compared with placebo oil (96178). A similar clinical study in the same population shows that using sesame oil extracted from tahini topically as part of a light massage for 5 minutes 3 times a day for 2 days improves pain severity, pain sensitivity, and heaviness of the painful site by about 20% when compared with baseline (106034). The lack of statistical comparison to the placebo group limits the validity of these findings.
Peptic ulcers. Although there is interest in using oral sesame for peptic ulcers, there is insufficient reliable information about the clinical effects of sesame for this purpose.
Rheumatoid arthritis (RA). It is unclear if oral sesame is beneficial for RA. Details: Preliminary clinical research in females with RA shows that taking the sesame constituent sesamin (Sesamin, Scivation, Inc.) 200 mg daily for 6 weeks improves physical function and reduces pain, the number of tender and swollen joints, and markers of inflammation such as C-reactive protein when compared with placebo (103230).
Stroke. Although there is interest in using oral sesame for stroke, there is insufficient reliable information about the clinical effects of sesame for this purpose. More evidence is needed to rate sesame for these uses.

SUNFLOWER OIL (Sunflower Fat-Soluble Extract)

POSSIBLY EFFECTIVE

Coronary heart disease (CHD). The U.S. Food and Drug Administration (FDA) allows a qualified health claim stating that using high-oleic acid sunflower oil as a replacement for other dietary fats and oils higher in saturated fat may reduce the risk of CHD. Details: A meta-analysis of clinical studies shows that replacing 7.5% of energy from partially hydrogenated vegetable oils with high-oleic acid sunflower oil can reduce CHD risk by about 9% to 19%. Furthermore, analysis of results from observational studies found that replacing partially hydrogenated oil with high-oleic acid sunflower oil is associated with a 16% to 35% reduction in the risk of CHD events (95745). The FDA allows for a qualified health claim that replacing dietary fats and oils higher in saturated fat with high-oleic acid sunflower oil may reduce the risk of CHD. To achieve this benefit, the use of high-oleic acid sunflower oil should not increase total daily energy intake. The suggested daily dietary intake is about 20 grams (1.5 tbsp) of high-oleic sunflower oil in place of other fats and oils (98563). Sunflower oil that contains high amounts of linoleic acid rather than oleic acid does not appear to improve cholesterol levels or reduce the risk of cardiovascular events in patients with CHD (96205).
Hypercholesterolemia. Consuming sunflower oil in the diet may reduce low-density lipoprotein (LDL) cholesterol levels in some patients. Details: There is evidence that using sunflower oil in the diet as 45-50 grams daily for up to 12 weeks is more effective than olive oil for decreasing LDL cholesterol and apolipoprotein B levels in healthy individuals (9780). Also, clinical research in patients with mild hyperlipidemia or moderate hypercholesterolemia shows that consuming specific brands of mid-oleic acid (NuSun) or high-oleic acid (Sunola, Meadow Lea Foods) sunflower oils as 15% to 20% of dietary calories for up to 5 weeks is more effective than olive oil or saturated fat for decreasing total cholesterol, LDL cholesterol, and apolipoprotein B levels (76697,76698). Also, consuming a high-oleic sunflower oil-rich diet for 3 weeks decreases total cholesterol levels to a greater extent than diets enriched with palm oil or medium-chain triglycerides in patients with mild hypercholesterolemia (67569). Other preliminary clinical research in patients with moderate hypercholesterolemia shows that consuming a diet rich in sunflower oil for 3 weeks decreases total cholesterol and LDL cholesterol levels when compared with baseline. However, levels of high-density lipoprotein (HDL) cholesterol appear to be lowered as well (76714). Despite these beneficial effects, sunflower oil might be less effective than some other dietary oils. Taking sunflower oil for 3 months appears to be less effective than rice bran oil for lowering cholesterol in patients with hypercholesterolemia (76699). Also, while consuming sunflower oil 45 grams daily, as part of the diet and as a supplement, for 12 weeks reduces levels of total cholesterol and LDL cholesterol when compared to baseline, it appears to be less effective at reducing total cholesterol levels than flaxseed oil in certain patients at risk for atherosclerosis (76696). In addition, taking sunflower oil 15.1 grams daily for 4 months does not appear to reduce levels of total or LDL cholesterol in patients with peripheral vascular disease (76691).

POSSIBLY INEFFECTIVE

Hypertension. Oral sunflower oil does not seem to lower blood pressure. Details: Preliminary clinical research in adults with hypertension shows that taking sunflower oil 30-40 grams daily for one year is less effective than extra-virgin olive oil for reducing blood pressure (5091). Also, clinical research in elderly adults with hypertension shows that taking 60 grams of sunflower oil daily for 4 weeks is less effective than virgin olive oil for reducing systolic blood pressure (76692).

INSUFFICIENT RELIABLE EVIDENCE to RATE

Atherosclerosis. It is unclear if oral sunflower oil is beneficial for atherosclerosis; some clinical research suggests that it may provide less benefit than other dietary oils. Details: Some preliminary clinical research in individuals with overweight and obesity shows that taking sunflower oil 30 mL (about 27 grams) daily for 90 days decreases carotid intima-media thickness (CIMT) by 3.5% when compared to baseline, but not when compared with olive oil or flaxseed oil. Sunflower oil also improves flow-mediated vasodilation by 73% when compared to baseline, compared with no improvement in those taking flaxseed oil or olive oil (99303). Other preliminary clinical research in individuals waiting for carotid endarterectomy shows that taking sunflower oil 6 grams daily for up to 189 days is less effective than the same dose of fish oil, and equivalent to control oil, for improving the status of atherosclerotic plaques (76688).
Atopic dermatitis (eczema). Although there is interest in using topical sunflower oil for atopic dermatitis, there is insufficient reliable information about the clinical effects of sunflower oil for this condition.
Child growth. It is unclear if topical sunflower oil is beneficial for early child growth. Details: A large preliminary clinical trial in newborn infants in India shows that exclusive topical application of 10 mL of high-linoleic acid sunflower oil, an average of 2.7 times daily for about one month, increases weight gain by 1.3 gram/kg daily when compared with a control group exclusively given traditional vigorous massage with mustard oil an average of 2.4 times daily. The increase in weight gain was highest for infants weighing less than 1500-2000 grams at birth (108141). However, it is unclear if any beneficial effects are due to the sunflower oil, the massage, their combination, or the lack of mustard oil.
Dry mouth. It is unclear if rinsing the mouth with sunflower oil is beneficial for dry mouth. Details: Preliminary clinical research in adults with moderate dry mouth associated with medication use shows that using a sunflower oil mouth rinse and gargling for 5-8 minutes before spitting it out twice daily for 7 days improves dry mouth scores by 23% when compared to baseline. Sunflower oil also improves the ability to swallow and sleep with dry mouth, but not other dry mouth symptoms or saliva flow rate, when compared with control (105523). This study may have been inadequately powered to detect a difference between groups.
Dry skin. It is unclear if topical sunflower oil is beneficial for dry skin in infants. Details: Preliminary clinical research in full-term, newborn infants shows that topical application of 4 drops of sunflower oil to each of three parts of the body twice daily for 4 weeks improves skin hydration, but not skin barrier function or the presence of redness or rash, when compared with not using topical oil. Furthermore, use of sunflower oil may impede the normal development of skin barrier function that occurs during the first four weeks of life (96144).
Fetal and premature infant mortality. It is unclear if topical sunflower oil is beneficial for preventing early mortality in premature infants. Details: A large clinical trial in newborn infants in India shows that exclusive topical application of 10 mL of high-linoleic acid sunflower oil, an average of 2.7 times daily for about one month, reduces infant mortality by 58% when compared to a control group exclusively given traditional vigorous massage with mustard oil an average of 2.4 times daily. A subgroup analysis of premature infants also shows a 52% reduction in mortality with the use of high-linoleic acid sunflower oil when compared with control (108143). However, it is unclear if any beneficial effects are due to the sunflower oil, the massage, their combination, or the lack of mustard oil.
Prematurity. Small to moderate-sized clinical studies suggest that topical sunflower oil might increase body weight, reduce length of hospital stay, and improve skin hydration and skin integrity in preterm neonates. Details: Preliminary clinical research in preterm infants with low birth weight shows that massaging for 5-10 minutes using sunflower oil 10 mL/kg three times daily for 2 weeks increases weight gain by approximately 35% over 2 months when compared with massage using no oil. Sunflower oil massage does not appear to increase length or head circumference (96145). A small clinical study in premature infants in the intensive care unit (ICU) shows that a similar massage with sunflower oil three times daily for 5 days shortens ICU stay by about 5 days when compared with no massage. Furthermore, over the ICU stay, infants in the sunflower oil massage group gained an average of 15 grams, whereas infants in the control group experienced weight loss (98479). The effect of sunflower oil on skin hydration and integrity in preterm infants has also been assessed. A clinical trial of 90 preterm infants in a Turkish neonatal ICU shows that whole body skin treatment (not massage) with either sunflower oil or almond oil 4 mL/kg four times daily for 5 days improves measures of skin hydration and skin integrity when compared with control infants that did not receive oil treatment. The sunflower and almond oil treatments are equally effective (105524). Another clinical study in 90 infants (42% preterm) in a Turkish neonatal ICU shows that whole body skin treatment (not massage) with sunflower oil or liquid Vaseline 3-4 mL for preterm and 5-6 mL for full-term infants daily for 16 days improves measures of skin integrity when compared with control infants that did not receive any oil treatment. Skin integrity scores were better in the sunflower oil group than liquid Vaseline at some time points (111726).
Psoriasis. Although there is interest in using topical sunflower oil for psoriasis, there is insufficient reliable information about the clinical effects of sunflower oil for this condition.
Rheumatoid arthritis (RA). Although there is interest in using oral sunflower oil for RA, there is insufficient reliable information about the clinical effects of sunflower oil for this condition.
Tinea pedis. It is unclear if topical sunflower oil is beneficial for tinea pedis. Details: Preliminary clinical research shows that topical application of a specific brand of ozonized sunflower oil (Oleozon) twice daily for 6 weeks is as effective as ketoconazole for curing athlete's foot (76687). More evidence is needed to rate sunflower oil for these uses.

VITAMIN A

EFFECTIVE

Vitamin A deficiency. Oral vitamin A is effective for treatment and prevention of vitamin A deficiency. Details: Clinical and observational research in children shows that taking vitamin A orally is effective for preventing and improving symptoms of vitamin A deficiency, including xerophthalmia, night blindness, and Bitot's spots (82329,82689,82710,90773). Vitamin A deficiency can occur due to abnormal storage and transport of vitamin A in people with abetalipoproteinemia, protein deficiency, diabetes mellitus, hyperthyroidism, fever, liver disease, and cystic fibrosis (7135). However, research suggests that supplementation with vitamin A may not be necessary for most newborns with vitamin A deficiency. An observational study in newborns with vitamin A levels of 0.43-0.59 mcmol/L or >0.59 mcmol/L found that vitamin A levels increased naturally over the first six months of life, regardless of oral vitamin A supplementation. However, in infants with very low vitamin A levels (<0.43 mcmol/L), vitamin A supplementation was associated with significant increases in vitamin A levels at 6 months of age when compared with no supplementation, suggesting that only newborns with very low vitamin A levels should receive oral vitamin A (107298).

POSSIBLY EFFECTIVE

Aging skin. Topical vitamin A (retinol) formulations seem to improve symptoms of aging skin, such as wrinkles and mottled pigmentation. Details: The vitamin A analog tretinoin (Renova) is a prescription drug approved by the U.S. Food and Drug Administration for adjunctive use in reducing fine wrinkles, hyperpigmentation, and tactile roughness of aging facial skin (103711). However, this drug is not interchangeable with non-prescription, commercially available vitamin A products, which have not been as extensively evaluated in clinical research. Although research evaluating non-prescription topical vitamin A shows benefit for reducing wrinkles, most studies have been small and used different formulations. One small study in adults over 40 years of age shows that applying a pea size amount of 0.075% retinol cream to the face daily for 26 weeks seems to reduce deep and fine wrinkling when compared with placebo. Applying a lower dose of 0.04% retinol cream for 13 weeks seems to reduce fine wrinkling to a lesser degree, with no effect on deep wrinkles, when compared with placebo cream (104458). Another small clinical study in adults over 80 years of age shows that applying 2 mL of retinol 0.4% lotion to the upper arm up to 3 times weekly for 24 weeks reduces visible wrinkles when compared with placebo (94683). Two small studies in females ages 33 to 65 show that applying retinol 0.15%, 0.3% and 0.5% in liquid crystal formulation once daily to the face for 2-3 months improves skin pigmentation, elasticity, and wrinkles when compared with baseline (103680,104464). The validity of these two studies is limited by the lack of a comparator treatment. Topical vitamin A is frequently combined with other ingredients in commercial formulations; however these combinations have rarely been studied. A small clinical study in adults over 35 years with skin aging shows that applying a cream containing retinol 0.5%, niacinamide, resveratrol, and hexylresorcinol seems to improve wrinkling and skin tone when compared with baseline (104455). Another small preliminary clinical trial in adults ages 35-65 years with periorbital lines and wrinkles shows that applying a cream containing retinol modestly improves dryness, puffiness, redness, and darkness when compared with baseline. The retinol was conjugated with lactic acid, and the cream contained other nutrient and herbal ingredients It was applied around the eyes each evening, sometimes used in combination with another product each morning (109747).
Bronchopulmonary dysplasia. Intramuscular vitamin A may reduce the risk of bronchopulmonary dysplasia (BPD) in very low birth weight infants when given at a dose of 5000 IU three times weekly for 28 days. Lower doses do not seem to be effective. It is unclear if enteral vitamin A is beneficial for BPD. Details: A meta-analysis of 6 clinical trials in premature infants shows that intramuscular administration of vitamin A every other day or three times weekly for 28 days reduces the risk of BPD by around 33% when compared with control (107297). The results from this meta-analysis are primarily driven by a modestly sized clinical trial in very low birth weight infants which shows that intramuscular administration of vitamin A 5000 IU three times weekly for 28 days reduces the risk of BPD by 15% when compared with a sham control (82195). A subgroup analysis of this trial suggests that infants with the lowest BPD risk estimate based on gestational age, birth weight, sex, ethnicity, and oxygen levels 24 hours after birth appear to benefit more from vitamin A therapy than those with higher BPD risk estimates (107296). Previous research in this area utilized a lower dose of only 2000 IU every other day for 28 days, and showed no significant improvement in the rate of BPD (82331,82613). The evaluation of a higher dose was prompted by research noting that the lower doses evaluated in these earlier studies were unable to achieve serum retinol concentrations above 25 mcg/dL, while doses at or above 5000 IU three times weekly could reach this level (82731). Enteral vitamin A has also been investigated. Meta-analyses of two clinical trials show that supplementation with vitamin A at an average of 5,000 IU daily, staring within four days of birth, does not reduce the incidence of BPD when compared with placebo (109750,109753).
Diarrhea. Vitamin A seems to reduce the incidence of diarrhea in young children. However, it is unclear if oral vitamin A while breastfeeding is beneficial for preventing diarrhea in nursing infants. Details: A meta-analysis of clinical research in children up to age 5 shows that vitamin A supplementation reduces the incidence of diarrhea by 15% and mortality related to diarrhea by 12% when compared with control, usually placebo or no supplementation (109755). However, one small clinical trial in breastfeeding parents shows that supplementation of vitamin A 1800 IU and ergocalciferol (vitamin D2) 600 IU daily for 2 months does not reduce the risk of diarrhea in the nursing infants when compared with placebo (107293).
Measles. High-dose oral vitamin A seems to reduce mortality from measles in children under 2 years of age and may also reduce the incidence of measles in children up to 5 years of age. Details: Meta-analyses of clinical research show that taking vitamin A does not reduce mortality in children with measles when all ages and/or doses are considered (82373,82502,95055,109755). However, in children with measles who are less than 2 years of age, taking vitamin A 200,000 IU orally for at least two doses seems to reduce mortality by up to 83% when compared with placebo (82373,82502). Also, taking vitamin A seems to reduce the incidence of measles in children ages 6 months to 5 years (95055,109755).
Night vision. Oral vitamin A as retinyl palmitate seems to reduce night blindness during pregnancy in malnourished patients. Details: Clinical research shows that taking vitamin A (as retinyl palmitate) 23,000 IU weekly before and during pregnancy reduces pregnancy-related night blindness by 37% in malnourished patients (6154). Some evidence suggests that zinc supplements might potentiate the effects of vitamin A in restoring sight in zinc-deficient pregnant patients affected by night blindness (8630).
Oral leukoplakia. High-dose oral vitamin A seems to reduce oral leukoplakia lesions in patients that chew tobacco and/or betel nut. Details: Clinical research in patients with tobacco and/or betel nut chewing habits shows that taking oral vitamin A 200,000-300,000 IU weekly for 6-12 months seems to result in remission of leukoplakia lesions in over 50% of participants when compared with placebo (34674,82617). However, it is unknown if vitamin A prevents the development of oral cancer from oral leukoplakia lesions.
Overall mortality. In children at risk for vitamin A deficiency, oral vitamin A seems to reduce mortality. However, it does not seem to reduce mortality in healthy adults. Details: Despite previous debate on whether the programs supplying high-dose vitamin A in low- and middle-income countries with prevalent vitamin A deficiency are safe and effective for reducing child mortality, most experts, including World Health Organization, recommend high-dose vitamin A supplementation for those children (95055,95724,97170,109755). In 2010, a meta-analysis of 17 trials involving over 194,000 patients, showed that vitamin A supplementation reduces all-cause mortality by about 24% in children 6 months to 5 years of age (82559). However, some research published after this meta-analysis shows conflicting results (90773,90777). In fact, the largest clinical trial conducted to date (Deworming and Enhanced Vitamin A; DEVTA), which was published after the analysis and involved one million preschool children, suggests that high-dose vitamin A supplementation does not reduce mortality (90773). However, this trial was limited due to under-resourcing and undetermined patient consent and treatment compliance (90773). Furthermore, in 2017, a meta-analysis including the DEVTA trial along with 46 additional studies involving over 1.2 million preschool children, shows that vitamin A supplementation does reduce all-cause mortality by 12% when compared with control (95055). This meta-analysis was updated in 2022 with no additional studies or changes in conclusions (109755). Adult mortality is not reduced by vitamin A supplementation. In fact, some evidence even shows that vitamin A supplementation increases mortality when administered to healthy adult patients or those with a stabilized disease (15305,34622,90775).
Postpartum complications. Oral vitamin A seems to reduce postpartum diarrhea and mortality in malnourished patients. Details: A large clinical study in malnourished pregnant patients in Nepal shows that taking vitamin A (as retinyl palmitate) 23,000 IU weekly before, during, and after pregnancy reduces the occurrence of blood and mucus in the stool by 93% and the occurrence of diarrhea by up to 90% during the first 6 months postpartum when compared with placebo (2581). Another clinical study in the same population shows that taking vitamin A (as retinyl palmitate) 23,000 IU weekly before and during pregnancy reduces pregnancy-related mortality by 40% when compared with placebo (6153).
Retinitis pigmentosa. Oral vitamin A supplementation in children with retinitis pigmentosa seems to slow retinal function decline. Details: Observational and clinical research in children with retinitis pigmentosa shows that taking an age-adjusted dose of vitamin A, up to a maximum dose of 15,000 IU daily, modestly attenuates the decline in retinal function when compared with control (83,97167,103677).
Ulcerative colitis. Oral vitamin A supplementation in patients with ulcerative colitis seems to improve clinical response and mucosal healing. Details: A clinical study in adults with symptomatic ulcerative colitis despite treatment with 5-aminosalicylic acid shows that taking vitamin A 25,000 IU daily for 2 months reduces disease severity and increases the rate of clinical response and mucosal healing when compared with placebo. The number needed to treat (NNT) for clinical response is 3; the NNT for mucosal healing is 5 (100329).
Wrinkled skin. Topical vitamin A (retinol) formulations seem to improve photodamage and wrinkles. Details: The vitamin A analog tretinoin (Renova) is a prescription drug approved by the U.S. Food and Drug Administration for adjunctive use in reducing fine wrinkles, hyperpigmentation, and tactile roughness of facial skin (103711). This drug is not interchangeable with non-prescription, commercially available vitamin A products, which have not been as extensively evaluated in clinical research. Still, some research in females ages 35-65 with moderately wrinkled and photoaged skin suggests that commercially available retinol formulations might reduce wrinkles and skin roughness similarly to tretinoin. One study used retinol serum starting at a concentration of 0.25% and increased to 1% over 3 months, compared with tretinoin cream 0.025% gradually increased to 0.1% (103671), while another study compared a gradual release tri-retinol 1.1% cream applied daily for 3 months to tretinoin 0.025% cream (104456). Commercial retinol also seems to be beneficial when compared with placebo. A small study in adults over 40 years old with photodamaged skin shows that applying stabilized retinol 0.1% to the face daily for one year improves wrinkles and mottled pigmentation in over 50% of the participants when compared with a placebo treatment (104463).

POSSIBLY INEFFECTIVE

Atopic disease. Supplementation with oral vitamin A does not seem to reduce the risk of atopy. Details: Clinical research in infants born in Guinea-Bissau shows that a single dose of vitamin A does not reduce the incidence of atopy when compared with placebo (90779,90780). Furthermore, giving a single dose of vitamin A to some infants, such as low birth weight infants and infants given Bacille Calmette-Guerin (BCG) vaccination, was associated with increased atopy and wheeze (90779).
Fetal and premature infant mortality. Giving oral vitamin A to malnourished adults during pregnancy and postpartum does not seem to reduce fetal, early infant, or first year mortality. Giving oral or intramuscular vitamin A to the infant also does not seem to reduce mortality in most patients. Details: Most meta-analyses of clinical research in malnourished patients suggest that vitamin A supplementation during pregnancy or postpartum does not reduce fetal, early infant, or first year mortality (6152,34601,34602,34627,82479,82566,82567,90774,90776,90782,90784,95057,109750,109753). Also, giving vitamin A supplements or intramuscular vitamin A to low birth weight infants does not appear to reduce mortality in these patients (82195,82431,82498,90778,90781,95053,107296,107297). Furthermore, vitamin A supplementation in term infants from low or middle income countries also does not appear to reduce the risk of mortality at 6 or 12 months of age when compared with placebo (95054,103674). Some evidence from a meta-analysis of clinical research shows that vitamin A supplementation may reduce the risk of mortality at 6 months in Asian infants, although it appears to increase the risk of mortality at 6 months in studies conducted in Africa. It also appears to increase the risk of mortality in female term infants by 12 months (95054).
Intestinal parasite infection. Oral high-dose vitamin A does not seem to prevent reinfection with intestinal parasites. Details: Clinical research in children living in Malaysia that were given albendazole 400 mg daily for 3-4 days for parasitic worms, shows that adding a single dose of vitamin A 200,000 IU does not help to prevent reinfection when compared with placebo (90772).
Melanoma. Oral vitamin A in patients with resected melanoma does not seem to improve survival and disease recurrence. Details: A clinical study in patients with completely resected melanoma shows that taking vitamin A 100,000 IU daily for 18 months does not increase disease-free survival when compared with no supplementation (82670).
Miscarriage. Oral vitamin A given to the mother does not prevent miscarriage or stillbirth. Details: A meta-analysis of clinical research shows that maternal supplementation with oral vitamin A, either alone or in combination with other vitamins, prior to or during early pregnancy does not reduce the risk of miscarriage or stillbirth when compared with control (104462).
Sepsis. Most research shows that oral vitamin A does not reduce the risk of sepsis in premature infants. Details: A meta-analysis of three clinical trials in premature infants shows that providing supplemental enteral vitamin A 1500-5000 IU daily, starting within four days of birth, does not reduce the incidence of sepsis when compared with placebo (109753).
Tuberculosis. Oral vitamin A does not seem to improve tuberculosis disease duration or mortality. Details: Low levels of vitamin A are common in patients with tuberculosis. However, taking vitamin A 2000 IU to 200,000 IU by mouth for 2-24 months does not improve symptoms, decrease disease duration, or reduce mortality when compared with placebo in these patients (82570,103668,109754). This may be due to the fact that vitamin A levels may normalize following the initiation of tuberculosis treatment, even without additional vitamin A supplementation.

LIKELY INEFFECTIVE

Head and neck cancer. Oral vitamin A taken for 2 years does not seem to improve survival or prevent head and neck cancer recurrence. Details: A large clinical study n patients with a history of head and neck cancer shows that taking vitamin A as retinyl palmitate 300,000 IU daily for 1 year, and followed by 150,000 IU daily for another year, does not reduce the risk of second primary tumors or tumor recurrence when compared with placebo. Also, vitamin A does not seem to improve survival or event-free survival (1710).
HIV transmission. Oral vitamin A does not reduce vertical HIV transmission risk. There is some concern that vitamin A might increase HIV transmission through breast milk. Details: Observational and intervention research shows that taking vitamin A orally does not decrease the risk of HIV transmission to the fetus during pregnancy, to newborns during delivery, or to infants during early breast-feeding (6376,82470,95059). Preliminary clinical research also shows that vitamin A supplementation of pregnant adults with HIV infection might increase the risk of HIV transmission to their babies through breast milk (9801).
Lower respiratory tract infections. Oral vitamin A does not reduce the risk for lower respiratory tract infections in children. It is unclear if supplementation of oral vitamin A while breast-feeding reduces the risk of lower respiratory tract infections in nursing infants. Details: Taking vitamin A by mouth does not prevent or reduce symptoms of lower respiratory tract infections, such as cough and fever, in children (82288,82443). Furthermore, some research shows that vitamin A is associated with a slight increase in the risk of respiratory tract infections when administered to children with adequate nutritional status (82288). Additionally, one small clinical trial in breast-feeding parents shows that supplementation of vitamin A 1800 IU and ergocalciferol (vitamin D2) 600 IU daily for 2 months does not reduce the risk of febrile illness or respiratory tract infections in the nursing infants when compared with placebo (107293).

INSUFFICIENT RELIABLE EVIDENCE to RATE

Acne. Although prescription vitamin A analogs are approved to treat acne, it is unclear if non-prescription topical vitamin A products help with acne symptoms. Details: The high-dose vitamin A analogs adapalene (Differin) and tazarotene (Tazorac) are prescription drugs approved by the US Food and Drug Administration for the treatment of acne (103712,103713). These drugs are not interchangeable with non-prescription, commercially available vitamin A products, such as retinol, which have not been extensively evaluated in clinical research. A small preliminary clinical trial in adolescents and young adults with mild to moderate acne shows that applying topical benzoyl peroxide 2.5% each morning and a topical retinol plus salicylic acid product each evening for 12 weeks modestly improves acne severity and other measures of complexion when compared with baseline. All patients also used the same cleanser twice daily (109748). The validity of this finding is limited by the lack of a comparator group.
Alcohol-related liver disease. Oral vitamin A has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: A small clinical study in patients with acute alcoholic hepatitis shows that taking vitamin A in combination with coenzyme Q10 and other vitamins and minerals daily for 6 months does not improve survival when compared with placebo (61392).
Asthma. It is unclear if oral vitamin A is beneficial for preventing asthma in children. Details: An observational study in children has found that higher dietary intake of vitamin A is associated with a lower risk of asthma. Children in the highest quartile of vitamin A intake (median of 2267 IU daily) at 7 years of age had improved lung function and 32% lower odds of asthma at 11-14 years of age when compared with children in the lowest quartile of vitamin A intake (median of 870 IU daily) (107291).
Atopic dermatitis (eczema). It is unclear if supplementation of oral vitamin A while breast-feeding is beneficial for preventing eczema in nursing infants. Details: One small clinical trial in breast-feeding parents shows that supplementation of vitamin A 1800 IU and ergocalciferol (vitamin D2) 600 IU daily for 2 months does not reduce the risk of eczema in the nursing infants when compared with placebo (107293).
Autism spectrum disorder. It is unclear if oral vitamin A is beneficial for improving symptoms of autism. Details: Children with autism spectrum disorder are at increased risk for vitamin A deficiency, and vitamin A levels have been inversely associated with autism symptoms. Preliminary clinical research shows that taking a single dose of vitamin A 200,000 IU slightly improves emotional response, communication, and other symptoms when compared to baseline (97168). The lack of a control group limits the validity of these findings. Another preliminary clinical study in children with autism and vitamin A deficiency shows that taking vitamin A 50,000 IU weekly for 6 months, but not as a single dose of 200,000 IU, seems to improve social impairment scores when compared with control. Controls were children with autism without vitamin A deficiency that did not take a supplement (104459).
Breast cancer. Although vitamin A intake has been associated with a reduced risk for breast cancer, it is unclear if vitamin A supplements are beneficial. Details: Epidemiological evidence has found an association between high intake of vitamin A and a reduced risk of breast cancer. A meta-analysis of epidemiological research has found that the adults with the highest intake of vitamin A, either from diet alone or also from supplements, reduces the odds of developing breast cancer by 16% when compared with the lowest intake (1444,34610,109752). However, the effects of supplemental vitamin A, specifically, are unclear.
Cataracts. It is unclear if oral vitamin A is beneficial for cataract prevention. Details: A large-scale population-based study has found that high dietary intake of vitamin A is associated with a reduced risk of nuclear cataracts (6378). Also, other population research has found that the highest dietary intake of vitamin A is associated with a 17% lower risk of cataracts when compared with the lowest intakes (90786). However, there is conflicting evidence regarding the association between blood levels of vitamin A and the risk of cataracts (90786,90944). It is not known if supplemental vitamin A is beneficial.
Cervical cancer. It is unclear if oral vitamin A is beneficial for cervical cancer prevention. Details: A meta-analysis of clinical research shows that increased vitamin A levels in the blood or higher vitamin A intakes are associated with a reduced risk of cervical cancer. However, this effect is observed when both forms of vitamin A, either retinol or carotenoids, are considered. When only the retinol form is considered, vitamin A supplementation does not seem to reduce the risk of cervical cancer (34613,109752). Also, a meta-analysis of epidemiological research has found that vitamin A intake, either from diet alone or supplements, does not affect the risk of cervical cancer (109752).
Chemotherapy-induced diarrhea. It is unclear if oral vitamin A helps to prevent diarrhea caused by chemotherapy. Details: A very small clinical study in children receiving chemotherapy shows that taking vitamin A orally does not seem to prevent GI adverse effects, including diarrhea and mouth pain, when compared with control (9802).
Child development. Oral vitamin A might improve growth and development in children with vitamin A deficiency, but not in those with good nutritional status. Details: Supplementing with vitamin A 60 mg for up to 9 years does not promote or improve child growth in children with appropriate nutritional status (20132). However, in children with vitamin A deficiency, supplementation with vitamin A may improve growth (82246).
Chronic obstructive pulmonary disease (COPD). There is limited evidence on the oral use of vitamin A in patients with emphysema. Details: Observational research has found that consuming recommended amounts of vitamin A in the diet is associated with 33% lower odds of developing emphysema (103678).
Colorectal adenoma. Oral vitamin A has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: Clinical research shows that taking a combination supplement containing selenium, zinc, vitamin A, vitamin C, and vitamin E orally daily for 5 years or until the recurrence of an adenoma reduces the risk of recurrent large-bowel adenomas by about 40% when compared with placebo in patients with large-bowel adenomas (92903). It is not clear if this benefit is due to vitamin A or other constituents.
Colorectal cancer. It is unclear if oral vitamin A is beneficial for colorectal cancer prevention. Details: Taking vitamin A alone or in combination with beta-carotene does not seem to reduce the risk of colorectal cancer (12185).
Coronary artery bypass graft (CABG) surgery. It is unclear if oral vitamin A improves recovery after CABG surgery. Details: Preliminary clinical research shows that taking vitamin A 5000 IU daily (as retinol palmitate) for 21 days starting on the day of CABG surgery reduces time in intensive care after surgery by 46% to 69% compared to a control group not given vitamin A (90783). Supplementation with vitamin A also improves total hospitalization time for those patients with adequate zinc status (90783).
Coronavirus disease 2019 (COVID-19). It is unclear if oral vitamin A is beneficial for the treatment of mild to moderate COVID-19. Details: Clinical research in COVID-19 outpatients treated with hydroxychloroquine shows that taking vitamin A 25,000 IU daily for 10 days modestly reduces the number of patients with symptoms of fever, body ache, and fatigue when compared with placebo. However, there was no effect on the number of patients with cough, shortness of breath, lack of appetite, chest pain, diarrhea, loss of smell, or headache (109745).
Depression. It is unclear if oral vitamin A is beneficial for depression. Details: A meta-analysis of observational research has found that dietary intake of vitamin A is inversely associated with depression. The highest intake of vitamin A was associated with a 17% reduced risk of depression when compared with the lowest intake. Also, vitamin A intake was lower in individuals with depression (109743). The effect of vitamin A supplementation is unclear.
Esophageal cancer. It is unclear if oral vitamin A is beneficial for esophageal cancer prevention. Details: Observational research has found that higher beta-carotene and vitamin A intake is associated with a reduced risk of esophageal cancer (34551,103675). However, evidence from higher-quality clinical research shows that taking vitamin A in combination with beta-carotene does not reduce the risk of esophageal cancer (12185).
Gastric cancer. It is unclear if oral vitamin A is beneficial for gastric cancer prevention. Details: Taking vitamin A alone and in combination with beta-carotene does not seem to reduce the risk of gastric cancer (12185).
Glaucoma. It is unclear if oral vitamin A is beneficial for glaucoma prevention. Details: A meta-analysis of observational research has found that a high dietary intake of vitamin A is associated with a 37% reduced risk of glaucoma when compared with a low intake (109742).
HIV/AIDS. It is unclear if oral vitamin A is beneficial for improving HIV/AIDs outcomes. Details: A meta-analysis of clinical trials and population research shows that maternal vitamin A supplementation of mothers with poor vitamin A status at baseline does not influence child or maternal mortality, hospitalization rate, or HIV/AIDS progression. However, pediatric vitamin A supplementation seems to decrease mortality rates in children with HIV/AIDS when compared with placebo (34529,95059).
HIV/AIDS-related diarrhea. It is unclear if oral vitamin A is beneficial for preventing diarrhea associated with HIV. Details: A large clinical trial shows that taking vitamin A can decrease the rate of diarrhea-specific mortality by up to 92% in vitamin A-deficient children with or without HIV/AIDS (1465). However, a meta-analysis of clinical research shows that taking vitamin A does not significantly reduce diarrhea-specific mortality when only children with HIV/AIDS are considered (82511). But vitamin A does appear to reduce overall mortality in these children by 50% to 63% (1465,82511).
Human papillomavirus (HPV). It is unclear if topical or oral vitamin A is beneficial for the resolution of genital warts caused by HPV. Details: A meta-analysis of small clinical trials in patients with genital warts suggests that the oral prescription drugs isotretinoin and etretinate might promote resolution of warts when compared with baseline. However, the topical prescription drug tretinoin 0.05% cream does not seem to help (104460). These drugs are not interchangeable with non-prescription, commercially available vitamin A products, such as retinol.
Infant development. It is unclear if intramuscular vitamin A improves the development of low birth weight infants. Details: A meta-analysis of clinical research shows that giving intramuscular vitamin A to very low birth weight infants reduces the risk of chronic lung disease at 36 weeks postmenstrual age by about 13% compared to control (95053). Preliminary clinical research also shows that giving intramuscular vitamin A along with inhaled nitric oxide gas for 3 weeks to low birth weight infants on mechanical ventilation might improve mental development at one year in some of these patients when compared with inhaled nitric oxide gas alone (90778). However, a meta-analysis of clinical research shows that intramuscular vitamin A does not improve neurodevelopment in very low birth weight infants (95053).
Iron deficiency anemia. It is unclear if oral vitamin A is beneficial for the prevention or treatment of anemia due to iron deficiency. Details: Some research in children and pregnant adults without anemia shows that taking vitamin A increases plasma levels of hemoglobin and ferritin, and may reduce the risk of developing anemia (9518,34627). However, another study in pregnant patients, half of whom had anemia at baseline and half of whom did not have anemia, shows that taking 3000 mcg retinol orally in combination with iron and folate does not improve hemoglobin or erythropoietin concentrations when compared with taking iron and folate (9188). In preterm infants with existing anemia, taking vitamin A 5000 IU and vitamin B complex 40 mg daily improves serum ferritin, hemoglobin, and reticulocyte levels and reduces the need for blood transfusions when compared with taking either vitamin alone. Taking vitamin A alone, however, does not improve these outcomes (100330).
Leukemia. It is unclear if oral vitamin A is beneficial for leukemia prevention. Details: Preliminary clinical research in adults with chronic myelogenous leukemia shows that taking a specific vitamin A product (Aquasol, Armour Pharmaceuticals) 50,000 IU orally daily in combination with busulfan therapy does not significantly increase progression-free survival or overall survival when compared with busulfan alone. Furthermore, supplementation with vitamin A plus busulfan seems to increase the percentage of patients who experience grade 2 toxicity by about 5-fold when compared with busulfan alone (82652).
Liver cancer. It is unclear if oral vitamin A is beneficial for liver cancer prevention. Details: Population research has found that vitamin A supplementation or serum levels of vitamin A are not associated with the risk of liver cancer (97169).
Lung cancer. It is unclear if oral vitamin A is beneficial for lung cancer treatment or prevention. Details: Population research has found that increased dietary intake of vitamin A is not associated with a reduced risk of lung cancer (35628). Furthermore, supplementation with vitamin A and beta-carotene seems to increase the risk of lung cancer in smokers or those exposed to asbestos (2642,34675). A large clinical trial in patients with existing lung cancer shows that vitamin A 300,000 IU daily for one year followed by 150,000 IU daily for a second year does not increase survival (1710). However, some clinical research shows that high-dose vitamin A 300,000 IU daily following curative lung cancer resection reduces the risk of new primary tumors in patients heavily exposed to tobacco (7875).
Malaria. It is unclear if oral vitamin A is beneficial for reducing symptoms of malaria in young children. Details: Taking vitamin A orally seems to help decrease symptoms of malaria in children less than 3 years of age living in endemic areas (1464). However, other clinical research shows that single doses of vitamin A 100,000 to 200,000 IU do not improve coma resolution, convulsions, fever, parasite clearance, or mortality in infants and children less than 5 years of age with cerebral malaria (90785).
Multiple sclerosis-related fatigue. It is unclear if oral vitamin A is beneficial for reducing fatigue in patients with multiple sclerosis. Details: Preliminary clinical research in patients with relapsing-remitting multiple sclerosis receiving interferon beta-1a shows that taking vitamin A 25,000 IU (as retinyl palmitate) (Zahravi Pharmaceutical) daily for 6 months followed by 10,000 IU daily for 6 months, improves physical, cognitive, and psychosocial fatigue when compared with placebo (95052).
Necrotizing enterocolitis (NEC). A meta-analysis of several small clinical trials suggests that intramuscular vitamin A does not seem to prevent NEC. Details: A meta-analysis of 3 small clinical studies in very low birth weight infants shows that intramuscular administration of vitamin A 1500-5000 IU every other day or three times weekly for 28 days does not reduce the risk of NEC when compared with a control (107297).
Non-Hodgkin lymphoma. It is unclear if oral vitamin A is beneficial for non-Hodgkin lymphoma prevention. Details: Population research has found that intake of vitamin A at levels above 2330 mcg daily is associated with a 17% lower risk of non-Hodgkin lymphoma when compared with those whose daily intake of vitamin A is less than 642 mcg per day (90945).
Nonmelanoma skin cancer. It is unclear if oral vitamin A is beneficial for nonmelanoma skin cancer prevention. Details: Observational research over 26 years found that higher dietary vitamin A intake is associated with a 12% reduced risk for cutaneous squamous cell carcinoma in healthy patients when compared with lower vitamin A intake (101673).
Oral clefts. It is unclear if oral vitamin A is beneficial for oral cleft prevention. Details: A meta-analysis of observational research has found that periconceptional use of vitamin A, from diet and/or supplements, is associated with a 13% reduced incidence of cleft lip alone or with a cleft palate, but is not associated with the risk of cleft palate alone, in the child (109751).
Osteoarthritis. Oral vitamin A has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: Clinical research in patients with osteoarthritis shows that taking a specific product containing vitamin A in combination with selenium, vitamin C, and vitamin E (Selenium ACE, Carls-Berghs Farmaceutiska AB) does not appear to alleviate symptoms when compared with placebo (74449).
Ovarian cancer. It is unclear if oral vitamin A is beneficial for ovarian cancer prevention. Details: Most observational research has found that increased dietary intake of vitamin A is associated with a reduced risk of developing ovarian cancer (9193,103679,109752). The most recent meta-analysis of epidemiological research has found that adults with the highest intake of vitamin A, either from diet alone or supplements, reduces the odds of developing ovarian cancer by 19% when compared with the lowest intake (109752).
Pancreatic cancer. It is unclear if oral vitamin A is beneficial for pancreatic cancer prevention. Details: A meta-analysis of observational research has found that higher intake of vitamin A is associated with a reduced risk of pancreatic cancer; however, this benefit appears to be limited to only hospital-based cases and studies conducted in Europe (95060). In contrast, a meta-analysis of clinical research shows that taking vitamin A in combination with beta-carotene does not reduce the risk of pancreatic cancer (12185).
Parkinson disease. It is unclear if oral vitamin A prevents Parkinson disease development. Details: Population research has found that blood levels or dietary intake of vitamin A are not associated with the risk of Parkinson disease (91164).
Photoreactive keratectomy. Oral vitamin A has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: A small clinical study shows that taking a specific product (Evitex capsules, Alcon) containing vitamin A along with vitamin E seems to improve healing after photoreactive keratectomy. High dose (50,000 to 75,000 IU) vitamin A in the form of retinol palmitate taken daily with vitamin E (alpha-tocopheryl nicotinate) 460-590 mg daily seems to accelerate re-epithelialization, reduce haze formation, and improve visual acuity in patients undergoing laser surgery for myopia (348).
Pneumonia. Oral vitamin A does not seem to prevent mortality related to pneumonia in children. However, it is unclear if vitamin A reduces symptom severity and hospitalization in children. Details: Clinical research in children living in developing countries shows that taking vitamin A orally does not prevent mortality related to pneumonia (1466,82362,82504,82717,109749). However, the evidence related to symptom duration and severity is mixed. A large study and early meta-analyses show that vitamin A does not prevent pneumonia or decrease the severity or length of hospitalization in children with pneumonia (1466,82362,82504,82717). A more recent meta-analysis also shows that giving vitamin A to children at or below 5 years of age does not affect the duration of hospitalization (109755). The best evidence to date comes from a recent meta-analysis of randomized clinical trials. This meta-analysis shows that, when given in combination with conventional therapy to children up to 10 years of age, vitamin A reduces the duration of symptoms including fever, cough, lung rale, and shortness of breath, as well as the duration of hospitalization and time to a negative X-ray, when compared with conventional therapy alone (109749). However, the number of trials evaluating each endpoint is small and more research is needed to confirm these findings.
Prematurity. It is unclear if vitamin A reduces the duration of hospitalization for premature infants. Details: A meta-analysis of four randomized controlled trials in preterm infants shows that providing supplemental enteral vitamin A 1500-5000 IU daily, starting within four days of birth, does not reduce the duration of hospitalization when compared with placebo (109750).
Prostate cancer. It is unclear if oral vitamin A is beneficial for prostate cancer prevention. Details: Observational studies suggest that dietary intake of vitamin A is not associated with a reduced risk of prostate cancer (14134).
Psoriasis. It is unclear if topical vitamin A is beneficial for psoriasis symptoms. Details: The vitamin A analog tazarotene (Tazorac) is a prescription drug that is approved by the U.S. Food and Drug Administration to treat stable plaque psoriasis covering up to 20% body surface area (103713). This drug is not interchangeable with non-prescription, commercially available vitamin A products, such as retinol.
Radiation proctopathy. It is unclear if oral vitamin A is beneficial for reducing chronic radiation proctopathy symptoms. Details: A small clinical study in patients experiencing chronic radiation proctopathy caused by pelvic radiotherapy shows that taking retinol palmitate 10,000 IU daily for 90 days might reduce rectal symptoms when compared with placebo (82350).
Retinopathy of prematurity. Most small studies show that oral or intramuscular vitamin A does not reduce the risk of retinopathy of prematurity (ROP). Details: A meta-analysis of 4 small clinical studies in very low birth weight infants shows that intramuscular administration of vitamin A 2000-10,000 IU every other day or three times weekly, or oral vitamin A 2000 IU daily, for 28 days does not reduce the risk of ROP when compared with a control (107297). Another meta-analysis of clinical research shows that providing supplemental enteral vitamin A 1500 IU or an average of 5000 IU daily, starting within four days of birth, does not reduce the incidence of severe ROP (109750,109753). However, a very small clinical study in preterm infants, which was not included in the meta-analysis, shows that receiving retinol palmitate drops 3000 IU/kg daily for 28 days reduces the risk of ROP by 88% when compared with no treatment (103672).
Urinary tract infections (UTIs). It is unclear if adding oral vitamin A to antibiotic therapy is beneficial for symptoms of acute pyelonephritis in young females. Details: A small clinical study in females 2-12 years of age with a first occurrence of acute pyelonephritis shows that taking vitamin A 1500 units/kg daily for 10 days in conjunction with antibiotics decreases the duration of fever by about 1.3 days and reduces urinary frequency by about 1.5 episodes per day when compared to taking placebo with antibiotics. Taking vitamin A might also reduce the occurrence of moderate or severe renal scarring after 6 months when compared with placebo (100327). The validity of these findings is limited by small study size and a high dropout rate.
Warts. It is unclear if topical or oral vitamin A improves the resolution of viral warts. Details: A meta-analysis of observational and clinical research in patients with viral warts suggests that receiving prescription oral retinoids (isotretinoin, acitretin, etretinate) seems to produce a 61% rate of wart resolution. Prescription topical retinoids seems to produce a 64% rate of wart resolution (104461). These drugs are not interchangeable with non-prescription, commercially available vitamin A products, such as retinol. More evidence is needed to rate vitamin A for these uses.

VITAMIN A

LIKELY SAFE ...when used orally or intramuscularly and appropriately. Vitamin A, as pre-formed vitamin A (retinol or retinyl ester), is safe in adults when taken in doses below the tolerable upper intake level (UL) of 10,000 IU (3000 mcg) per day (7135). Higher doses increase the risk of side effects. There is also growing concern that taking high doses of antioxidants such as vitamin A might do more harm than good. In an analysis of studies, taking vitamin A supplements alone or in combination with other antioxidants is associated with an increased risk of mortality from all causes (15305,90775). Keep in mind that vitamin A is available in two different forms: pre-formed vitamin A (retinol or retinyl ester) and provitamin A (carotenoids). The safety concerns associated with high vitamin A intake occur with pre-formed vitamin A only. Some supplements contain vitamin A in both pre-formed and provitamin A forms. For these supplements, the amount of pre-formed vitamin A should be used to determine if the amount of vitamin A is safe.

POSSIBLY SAFE ...when used topically and appropriately, short-term. Retinol 0.5% has been used on the skin daily for up to 12 weeks with apparent safety. No serious adverse effects have been reported in clinical trials (103671,103680).

POSSIBLY UNSAFE ...when used orally in high doses. Doses higher than the UL of 10,000 IU (3000 mcg) per day of pre-formed vitamin A (retinol or retinyl ester) might increase the risk of side effects (7135). While vitamin A 25,000 IU (as retinyl palmitate) daily for 6 months followed by 10,000 IU daily for 6 months has been used with apparent safety in one clinical trial (95052), prolonged use of excessive doses of vitamin A can cause significant side effects such as hypervitaminosis A. The risk for developing hypervitaminosis A is related to total cumulative dose of vitamin A rather than a specific daily dose (1467,1469). There is also concern that taking high doses of antioxidants such as vitamin A might do more harm than good. In an analysis of studies, taking vitamin A supplements alone or in combination with other antioxidants is associated with an increased risk of mortality from all causes (15305,90775). There is insufficient reliable information available about the safety of using sublingual formulations of vitamin A.

CHILDREN: LIKELY SAFE
when used orally or intramuscularly and appropriately. The amount of pre-formed vitamin A (retinol or retinyl ester) that is safe depends on age. For children up to 3 years of age, doses less than 2000 IU (600 mcg) per day seem to be safe. For children ages 4 to 8, doses less than 3000 IU (900 mcg) per day seem to be safe. For children ages 9 to 13, doses less than 5667 IU (1700 mcg) per day seem to be safe. For children 14 to 18, doses less than 9333 IU (2800 mcg) per day seem to be safe (7135). Keep in mind that vitamin A is available in two different forms: pre-formed vitamin A (retinol or retinyl ester) and provitamin A (carotenoids). The safety concerns associated with high vitamin A intake occur with pre-formed vitamin A only. Some supplements contain vitamin A in both pre-formed and provitamin A forms. For these supplements, the amount of pre-formed vitamin A should be used to determine if the amount of vitamin A is safe.

CHILDREN: POSSIBLY UNSAFE
when pre-formed vitamin A (retinol or retinyl ester) is used orally in excessive doses. For children up to 3 years of age, avoid doses greater than 2000 IU (600 mcg) per day. For children ages 4 to 8, avoid doses greater than 3000 IU (900 mcg) per day. For children ages 9 to 13, avoid doses greater than 5667 IU (1700 mcg) per day. For children ages 14 to 18, avoid doses greater than 9333 IU (2800 mcg) per day (7135). Higher doses of vitamin A supplementation have been associated with increased risk of side effects such as pneumonia, bone pain, and diarrhea (319,95051). Long-term supplementation with low to moderate doses on a regular basis can cause severe, but usually reversible, liver damage (11978).

PREGNANCY AND LACTATION: LIKELY SAFE
when used orally or intramuscularly and appropriately. Vitamin A, as pre-formed vitamin A (retinol or retinyl ester), is safe during pregnancy and lactation when used in doses less than 10,000 IU (3000 mcg) per day (7135,16823,107293). Keep in mind that vitamin A is available in two different forms: pre-formed vitamin A (retinol or retinyl ester) and provitamin A (carotenoids). The safety concerns associated with high vitamin A intake occur with pre-formed vitamin A only. Some supplements contain vitamin A in both pre-formed and provitamin A forms. For these supplements, the amount of pre-formed vitamin A should be used to determine if the amount of vitamin A is safe.

PREGNANCY AND LACTATION: POSSIBLY UNSAFE
when used orally or intramuscularly in excessive doses. Daily intake of greater than 10,000 IU (3000 mcg) can cause fetal malformations (3066,7135). Excessive dietary intake of vitamin A has also been associated with teratogenicity (11978). The first trimester of pregnancy seems to be the critical period for susceptibility to vitamin A-associated birth defects such as craniofacial abnormalities and abnormalities of the central nervous system (7135). Pregnant patients should monitor their intake of pre-formed vitamin A (retinol or retinyl ester). This form of vitamin A is found in several foods including animal products, some fortified breakfast cereals, and dietary supplements (3066).

SESAME (organic Sesame seed Oil)

ANTIDIABETES DRUGS

Interaction Rating = Moderate Be cautious with this combination.

Severity = Moderate • Occurrence = Possible • Level of Evidence = D

Taking sesame oil with antidiabetes drugs might increase the risk of hypoglycemia.

Details

Clinical studies show that sesame oil can decrease plasma glucose and glycated hemoglobin (HbA1c) levels. Some clinical research in patients taking glibenclamide shows that using sesame oil or a blend of sesame oil and rice bran oil in place of other oil for cooking reduces plasma glucose more than glibenclamide alone (27654,28139,96177,108350,108352,108355). Monitor blood glucose levels closely. Dose adjustments might be necessary.

ANTIHYPERTENSIVE DRUGS

Interaction Rating = Moderate Be cautious with this combination.

Severity = Moderate • Occurrence = Probable • Level of Evidence = D

Taking sesame oil with antihypertensive drugs might increase the risk of hypotension.

Details

Clinical research shows that replacing other cooking oil with sesame oil can lower systolic blood pressure (SBP) and diastolic blood pressure (DBP) in patients with or without hypertension. There is also some evidence that sesame oil has additive effects in patients also taking atenolol, nifedipine, and/or hydrochlorothiazide (27652,27654,27655,96179,108355,108357). In patients using nifedipine, using a blend of sesame oil and rice bran oil for cooking reduces both SBP and DBP more than nifedipine alone (96180).

CYTOCHROME P450 2C9 (CYP2C9) SUBSTRATES

Interaction Rating = Moderate Be cautious with this combination.

Severity = Moderate • Occurrence = Possible • Level of Evidence = D

Theoretically, sesame might increase the levels and clinical effects of CYP2C9 substrates.

Details

In vitro, sesame inhibits CYP2C9 (11028). However, this interaction has not been reported in humans.

P-GLYCOPROTEIN SUBSTRATES

Interaction Rating = Minor Be watchful with this combination.

Severity = Mild • Occurrence = Possible • Level of Evidence = D

Theoretically, sesame might alter the transport of P-glycoprotein substrates.

Details

In vitro research suggests that sesamin, a constituent of sesame, can inhibit the multi-drug transporter protein, P-glycoprotein (28319,28320). However, this interaction has not been reported in humans.

TAMOXIFEN (Nolvadex)

Interaction Rating = Moderate Be cautious with this combination.

Severity = High • Occurrence = Possible • Level of Evidence = D

Theoretically, sesame might interfere with tamoxifen.

Details

In animal research, sesame seed reduces the tumor-inhibitory effect of tamoxifen by reducing apoptosis and increasing proliferation (28110,28111). This interaction has not been reported in humans.

SUNFLOWER OIL (Sunflower Fat-Soluble Extract)

ANTIDIABETES DRUGS

Interaction Rating = Moderate Be cautious with this combination.

Severity = Moderate • Occurrence = Possible • Level of Evidence = B

Theoretically, sunflower oil might decrease the effectiveness of antidiabetes medications.

Details

A diet using sunflower oil as a fat source can cause increased fasting blood glucose levels in patients with type 2 diabetes (8132). Dose adjustments to diabetes medications might be necessary.

VITAMIN A

HEPATOTOXIC DRUGS

Interaction Rating = Moderate Be cautious with this combination.

Severity = High • Occurrence = Possible • Level of Evidence = C

Theoretically, taking high doses of vitamin A in combination with other potentially hepatotoxic drugs might increase the risk of liver disease.

Details

The tolerable upper intake level (UL) is the highest level of intake that is likely to pose no risk of adverse effects. Doses of vitamin A above the UL can cause hepatotoxicity, ranging from elevated liver enzymes to liver failure (7135,82554).

RETINOIDS

Interaction Rating = Major Do not take this combination.

Severity = High • Occurrence = Probable • Level of Evidence = D

Concomitant use of retinoids with vitamin A supplements might produce supratherapeutic vitamin A levels.

Details

Retinoids, which are vitamin A derivatives, could have additive toxic effects when taken with vitamin A supplements (3046).

TETRACYCLINE ANTIBIOTICS

Interaction Rating = Moderate Be cautious with this combination.

Severity = High • Occurrence = Possible • Level of Evidence = D

Theoretically, taking tetracycline antibiotics with high doses of vitamin A can increase the risk of pseudotumor cerebri.

Details

Benign intracranial hypertension (pseudotumor cerebri) can occur with tetracyclines and with acute or chronic vitamin A toxicity. Case reports suggest that taking tetracyclines and vitamin A concurrently can increase the risk of this condition (10545,10546,10547). Avoid high doses of vitamin A in people taking tetracyclines chronically.

WARFARIN (Coumadin)

Interaction Rating = Moderate Be cautious with this combination.

Severity = High • Occurrence = Possible • Level of Evidence = D

Theoretically, high doses of vitamin A could increase the risk of bleeding with warfarin.

Details

Vitamin A toxicity is associated with hemorrhage and hypoprothrombinemia, possibly due to vitamin K antagonism (505). Advise patients taking warfarin to avoid doses of vitamin A above the tolerable upper intake level of 10,000 IU/day for adults.

Examination revealed diffuse, confluent edema and erythema on the face, eyelids, ears, hands, forearms, and distal humeral regions. The dermatitis improved with treatment; re-exposure to alfalfa resulted in a similar reaction (30609).

Endocrine ...Alfalfa contains constituents, including coumestrol, with reported estrogenic activity (30586,30592,4753). Effects in humans are not known.
One case report documents hypokalemia in a female who had been drinking a "cleansing tea" containing alfalfa, licorice, and stinging nettle. The potassium level returned to normal after discontinuing the tea and initiating potassium supplementation. The specific cause of the hypokalemia is not clear. Notably, both stinging nettle and licorice have been associated with hypokalemia and may have been responsible for this effect (30562).

Gastrointestinal ...Orally, flatulence and bulkier feces were reported during the first week of a case series of three subjects ingesting alfalfa (30598). In a case series of 15 patients ingesting alfalfa, increased fecal volume and increased stool frequency was reported. Additional adverse effects included abdominal discomfort in two patients, diarrhea in two patients, loose stools in six patients, and intestinal gas in 13 patients (5816).

Hematologic ...Pancytopenia and splenomegaly were reported in a 59-year-old male who had been taking 80-160 grams of ground alfalfa seeds for up to six weeks at a time, for a five month period. Hematologic values and spleen size returned to normal when alfalfa was discontinued (381).

Other ...Alfalfa products, including sprouts, seeds, and tablets, have been found to be contaminated with Escherichia coli, Salmonella, and Listeria monocytogenes, which have caused documented infections (5600,30566,30568,30572,30569,30564,30604,30610,30563,30607) (30566,30564,30604,30610,30563,30607,30576).
Orally, alfalfa has been associated with the development of a lupus-like syndrome in animals and humans (30594,14828,14830,30602), as well as with possible exacerbations of lupus in patients with known systemic lupus erythematosus (SLE). These reactions may be associated with the amino acid L-canavanine (30594), which appears to be present in alfalfa seeds and sprouts, but not leaves, and therefore should not be present in alfalfa tablets manufactured from the leaves (30601). However, case reports have included individuals ingesting tablets. A lupus-like syndrome was described in four patients taking 12-24 alfalfa tablets per day. Symptoms included arthralgias, myalgias, and rash; positive antinuclear antibodies (ANA) arose anywhere from three weeks to seven months after initiating alfalfa therapy. Upon discontinuation of alfalfa tablets, all four patients became asymptomatic. In two patients, ANA levels normalized (14828). Two additional reports have documented possible exacerbation or induction of SLE associated with alfalfa use. One case involved a female with a 26-year history of SLE, who had been taking 15 tablets of alfalfa daily for nine months prior to an exacerbation. Because of the delay in onset of the exacerbation from the initiation of alfalfa therapy, causation cannot be clearly established (30575). In a different report, SLE and arthritis were found in multiple family members who had been taking a combination of vitamin E and alfalfa tablets for seven years (30602). It is not known what other environmental or genetic factors may have affected these individuals, and the association with alfalfa is unclear.

BUCKWHEAT (organic Buckwheat)

General ...Orally, buckwheat seems to be well tolerated (11438,11442). However, allergic reactions to buckwheat can occur in some adults and children. Symptoms can include skin sensitization, allergic rhinitis, asthma, conjunctivitis, nausea, vomiting, and anaphylaxis (11435,11436,11437,96060,96061). Occupational exposure to buckwheat, or household exposure through sleeping on a buckwheat husk stuffed-pillow can cause sensitization, of which symptoms include allergic rhinitis and asthma (11437,11443).

Immunologic ...Orally, buckwheat seems to be well tolerated (11438,11442). However, allergic reactions to buckwheat can occur in some adults and children. Symptoms can include skin sensitization, allergic rhinitis, asthma, conjunctivitis, nausea, vomiting, and anaphylaxis (11435,11436,11437,96060,96061).
Occupational exposure to buckwheat, or household exposure through sleeping on a buckwheat husk stuffed-pillow can cause sensitization, of which symptoms include allergic rhinitis and asthma (11437,11443).

CARROT (organic Carrot)

General ...Orally, carrot is well tolerated when consumed as a food. It also seems to be generally well-tolerated when consumed as a medicine. Some people are allergic to carrot; allergic symptoms include anaphylactic, cutaneous, respiratory, and gastrointestinal reactions such as hives, swelling of the larynx, asthma, or diarrhea (25820,93606,106560). In infants, excessive consumption of carrot products in nursing bottles has been reported to cause extensive caries in the primary teeth (25817).
Topically, carrot has been associated with a case of phytophotodermatitis (101716).

Dental ...Orally, feeding carrot juice to infants, with or without sugar- or acid-containing beverages, has been reported to damage teeth and cause dental caries (25817).

Dermatologic ...Orally, excessive consumption of carrots or carrot-containing products can cause yellowing of the skin, which results from increased beta-carotene levels in the blood (25817). Carrots may cause allergic reactions in some patients. Allergic responses to carrot-containing foods include skin reactions such as hives, erythema, swelling, and/or papules (25820,96306).

Gastrointestinal ...Orally, carrots may cause allergic reactions in some patients. Allergic responses to carrot-containing foods can include gastrointestinal symptoms, such as diarrhea (25820).

Immunologic ...Orally, carrots may cause allergic reactions in some patients (25820,96306,106560). Allergic responses to carrot-containing foods can include skin reactions such as hives, erythema, swelling, and/or papules (25820,96306). For one patient, treatment of skin lesions resolved after a month of oral antihistamines and topical steroids, and avoiding further contact with carrot (96306). Allergic responses to carrot-containing foods can also include gastrointestinal symptoms, such as diarrhea, and respiratory symptoms, such as swelling of the larynx or asthma (25820). In one case, a patient with a history of allergic rhinitis and asthma who had been successfully treated with subcutaneous immunotherapy and was tolerant of consumption of raw and cooked carrots developed rhinoconjunctivitis when handling carrots. Inhalation of dust particles and aerosols produced by food processing activities and containing allergens from the peel and pulp of carrots is thought to have sensitized the airway, producing a distinct form of respiratory food allergy in which there are typically no symptoms with ingestion (106560).
Topically, a female runner developed phytophotodermatitis, which was considered possibly associated with the inclusion of carrot in a sunscreen (Yes To Carrots Daily Facial Moisturizer with SPF 15; Yes to, Inc.) (101716).

Psychiatric ...Compulsive carrot eating is a rare condition in which the patient craves carrots. According to one case report, withdrawal symptoms include nervousness, cravings, insomnia, water brash, and irritability (25821).

SESAME (organic Sesame seed Oil)

General ...Orally, topically, or intranasally, sesame seems to be well tolerated.
Most Common Adverse Effects:
All routes of administration: Allergic reactions.

Dermatologic ...In a small clinical study, one patient using a cream containing sesame oil as well as aqueous extracts of guggul and Allium ampeloprasum complained of rash at the application site (105751). It is unclear if this reaction was due to sesame, other ingredients, or other factors.

Gastrointestinal ...There was a single case of diarrhea associated with oral sesame in a clinical trial (108356).

Immunologic ...Multiple cases of allergic response to sesame seed occurring after occupational, topical, intramuscular, or oral exposure have been reported (28157,28158,28159,28160,28161,28162,28163,28166,28167,28183)(28184,28185,28186,28188,108348). One study found that up to 0.5% of the United States population reports having a sesame allergy, and 0.23% of the population meets criteria for an IgE-mediated allergic reaction to sesame (100501). Allergic symptoms may be dermatologic, such as angioedema (28160,28167,108348), cheilitis (28207), dermatitis (28157,28166,28182,28185,28186), edema (28159), erythema (28167), pruritis (28167,108348), purpura (28188), flushing (108348), and urticaria (28159,28160,28162,108348); musculoskeletal (28188); respiratory, such as asthma (28159,28162), rhinitis (28162), wheezing (28167), and general breathing difficulties (108348); gastrointestinal, such as vomiting (28159,108348); and others such as conjunctivitis (28159), anaphylactic shock (28157,28159,28160,28167,28177,28178,28179,28180,28204,108348), and hemodynamic modifications (28169). In Canada, sesame accounted for 4% of pediatric food-induced anaphylaxis reactions presenting to emergency departments over a 10-year period. The majority of cases were mild to moderate in severity and occurred within 2 hours of exposure; however, about 3% occurred 2-8 hours after exposure. Epinephrine was the most common treatment, followed by antihistamines, inhaled beta-agonists, and corticosteroids (108348).
Approximately one-third of patients with IgE-mediated sesame allergy have reported previous use of epinephrine due to this allergy (100501). There is evidence that IgE-mediated sesame allergy is influenced by both genetic and environmental factors; there was a high correlation of the allergy between family members, especially siblings (28175).
Allergens believed to be responsible for sesame seed hypersensitivity include beta-globulin (28213); sesamol, sesamolin, and sesamin (28182,28207); storage proteins including ses i 1 and ses i 2 (2S albumins) (28132,28187,28211,28212,28216,28217), ses i 3 (a 7S vicilin-type globulin) (28187,28214), ses i 4 (28158), ses i 5 (28158), ses i 6 (an 11S globulin) (28132,28215), and ses i 7 (28215). Typically allergens in sesame seeds that cause reactions after oral intake have molecular weights ranging from 8-62 kDa (28208,28210).

Pulmonary/Respiratory ...In clinical trials involving a sesame oil nasal spray, minor adverse effects included adverse smell, oil dripping from the nose, and nasal blockage (27659).

SUNFLOWER OIL (Sunflower Fat-Soluble Extract)

General ...Orally and topically, sunflower oil is well tolerated.
Serious Adverse Effects (Rare):
Orally: Allergic reactions in sensitive individuals have been reported.

Immunologic ...Orally, sunflower oil can cause an allergic reaction in individuals sensitive to the Asteraceae/Compositae family. Members of this family include ragweed, chrysanthemums, marigolds, daisies, and many other herbs. However, the protein content of sunflower oil is very low. In one case report, an allergic response to sunflower oil did not occur despite presenting with severe allergy and anaphylaxis to sunflower seed (108140).

VITAMIN A

General ...Orally, vitamin A is generally well-tolerated at doses below the tolerable upper intake level (UL).
Serious Adverse Effects (Rare):
Orally: In very high doses, vitamin A can cause pseudotumor cerebri, pain, liver toxicity, coma, and even death.

Dermatologic ...Chronic oral use of large amounts of vitamin A causes symptoms of vitamin A toxicity including dry skin and lips; cracking, scaling, and itchy skin; skin redness and rash; hyperpigmentation; shiny skin, and massive skin peeling (7135,95051). Hypervitaminosis A can cause brittle nails, cheilitis, gingivitis, and hair loss (15,95051). Adverse effects from a single ingestion of a large dose of vitamin A is more common in young children than adults (15). In children, approximately 25,000 IU/kg can cause skin redness and generalized peeling of the skin a few days later and may last for several weeks (15).

Gastrointestinal ...There is some evidence that oral vitamin A supplementation might increase the risk of diarrhea in children. Although vitamin A can prevent diarrhea and reduce mortality in malnourished children, doses as low as 10,000 IU weekly for 40 weeks have been associated with diarrhea in well-nourished children (319). Diarrhea (82326,82389), nausea (7135,100329), abdominal pain (95051), abdominal fullness (100329), and vomiting (7135,82559,95051,95055,109755) have been reported following use of large doses of oral vitamin A. Adverse effects from a single ingestion of a large dose of vitamin A is more common in young children than adults (15). In children, approximately 25,000 IU/kg can cause vomiting and diarrhea (15). Chronic use of large amounts of vitamin A causes symptoms of vitamin A toxicity including anorexia, abdominal discomfort, and nausea and vomiting (7135).

Genitourinary ...Hypervitaminosis A can cause reduced menstrual flow (15). Intravaginally, all-trans retinoic acid can cause vaginal discharge, itching, irritation, and burning (9199).

Hematologic ...Hypervitaminosis A can cause spider angiomas, anemia, leukopenia, leukocytosis, and thrombocytopenia (15,95051).

Hepatic ...Since the liver is the main storage site for vitamin A, hypervitaminosis A can cause hepatotoxicity, with elevated liver enzymes such as alanine aminotransferase (ALT, formerly SGPT) and aspartate aminotransferase (AST, formerly SGOT), as well as fibrosis, cirrhosis, hepatomegaly, portal hypertension, and death (6377,7135,95051).

Musculoskeletal ...Vitamin A can increase the risk for osteoporosis and fractures. Observational research has found that chronic, high intake of vitamin A 10,000 IU or more per day is associated with an increased risk of osteoporosis and hip fracture in postmenopausal adults, as well as overall risk of fracture in middle-aged males (7712,7713,9190). A meta-analysis of these and other large observational studies shows that high dietary intake of vitamin A or retinol is associated with a 23% to 29% greater risk of hip fracture when compared with low dietary intake (107294). High serum levels of vitamin A as retinol also increase the risk of fracture in males. Males with high serum retinol levels are seven times more likely to fracture a hip than those with lower serum retinol levels (9190). Vitamin A damage to bone can occur subclinically, without signs or symptoms of hypervitaminosis A. Some researchers are concerned that consumption of vitamin A fortified foods such as margarine and low-fat dairy products in addition to vitamin A or multivitamin supplements might cause excessive serum retinol levels. Older people have higher levels of vitamin A and might be at increased risk for vitamin A-induced osteoporosis.
Vitamin A's effects on bone resorption could lead to hypercalcemia (95051).
Hypervitaminosis can cause slow growth, premature epiphyseal closure, painful hyperostosis of the long bones, general joint pain, osteosclerosis, muscle pain, and calcium loss from the bones (15,95051). One child experienced severe bone pain after taking vitamin A 600,000 IU daily for more than 3 months (95051). Vitamin A was discontinued and symptoms lessened over a period of 2 weeks. The patient made a full recovery 2 months later.

Neurologic/CNS ...Orally, adverse effects from a single large dose of vitamin A are more common in young children than adults (15). Headache, increased cerebrospinal fluid pressure, vertigo, and blurred vision have been reported following an acute oral dose of vitamin A 500,000 IU (7135). In children, approximately 25,000 IU/kg can cause headache, irritability, drowsiness, dizziness, delirium, and coma (15). Chronic use of large amounts of vitamin A causes symptoms of vitamin A toxicity including fatigue, malaise, lethargy, and irritability (7135).
There are reports of bulging of the anterior fontanelle associated with an acute high oral dose of vitamin A in infants (7135,90784,95053,95054). In children, approximately 25,000 IU/kg can cause increased intracranial pressure with bulging fontanelles in infants (15). Also, muscular incoordination has been reported following short-term high doses of vitamin A (7135).
A case of intracranial hypertension involving diffuse headaches and brief loss of vision has been reported secondary to topical use of vitamin A. The patient was using over-the-counter vitamin A preparations twice daily including Avotin 0.05% cream, Retin-A gel 0.01%, and Isotrexin gel containing isotretinoin 0.05% and erythromycin 2%, for treatment of facial acne. Upon exam, the patient was noted to have bilateral optic disc edema. The patient discontinued use of topical vitamin A products. Two months later, the patient reported decreased headaches and an improvement in bilateral optic disc edema was seen (95056).

Ocular/Otic ...In children, oral vitamin A approximately 25,000 IU/kg can cause swelling of the optic disk, bulging eyeballs, and visual disturbances (15). Adverse effects from a single ingestion of a large dose of vitamin A are more common in young children than adults (15).

Oncologic ...There is concern that high intake of vitamin A might increase some forms of cancer. Population research suggests high vitamin A intake might increase the risk of gastric carcinoma (9194).

Psychiatric ...Chronic oral use of large amounts of vitamin A causes symptoms of vitamin A toxicity, which can include symptoms that mimic severe depression or schizophrenic disorder (7135).

Pulmonary/Respiratory ...There is some evidence that oral vitamin A supplementation might increase the risk of pneumonia and diarrhea in children. Although vitamin A can prevent diarrhea and reduce mortality in malnourished children, doses as low as 10,000 IU weekly for 40 weeks have been associated with pneumonia and diarrhea in well-nourished children (319). In preschool children, high-dose vitamin A also increases the risk of respiratory infection (82288).

Other ...Chronic use of large amounts of vitamin A (>25,000 IU daily for more than 6 years or 100,000 IU daily for more than 6 months) can cause symptoms of vitamin A toxicity including mild fever and excessive sweating (7135). High intakes of vitamin A may result in a failure to gain weight normally in children and weight loss in adults (15).
