Below is general information about the safety of the known ingredients contained in the product Lutein Vision Advanced. Some ingredients may not be listed. This information does NOT represent a recommendation for or a test of this specific product as a whole.
LIKELY SAFE ...when used orally and appropriately. Doses of 3 grams per day and less can be safely used by most people. Fish oil has Generally Recognized As Safe (GRAS) status in the US (1313,1024,2299,2300,2301,2302,2315,2317,4912,5702)(5705,5706,6394,6399,7368,7369,7380,12921,12922,13011)(13766,14382,16733,17408,17991,17992,66454,89325,89336,89346)(89351,89352,89373,89374,101543,103492,103499,103502,104546,105220)(107180,107181,113220). Although higher doses of fish oil, such as 6 grams daily for up to 1 year, have been used safely (89344), there are some safety concerns about using high doses of fish oil. Some older research suggests that doses greater than 3 grams per day can inhibit blood coagulation and potentially increase bleeding risk (8671,8679,8696,66258,21223,21224). However, the most rigorous research to date shows that short-term doses of fish oil 10 grams daily and long-term doses of 1.5 grams daily for up to 52 weeks do not increase the risk of bleeding or affect coagulation parameters in chronically ill and vulnerable patients (97180). Still, doses greater than 3 grams per day might suppress immune response (1313,7384). Patients should only take high-dose fish oil while under medical supervision.
POSSIBLY SAFE ...when parenteral nutrition supplemented with a lipid emulsion enriched in fish oil is used, short-term. Fish oil or omega-3 fatty acid lipid emulsions, administered intravenously for 1-4 weeks, have been safely used (1004,66042,66421,89323,103497).
POSSIBLY UNSAFE ...when fish oil from dietary sources is consumed in large amounts. Fatty fish can contain significant amounts of toxins such as mercury, polychlorinated biphenyls (PCBs), dioxin, and dioxin-related compounds. Very frequent consumption of contaminated fish can cause adverse effects such as tremor, numbness and tingling, difficulty concentrating, and vision problems. Avoid frequent consumption of swordfish, king mackerel, tilefish (also called golden bass or golden snapper), and farm-raised salmon (12964,12965,12966). There is insufficient reliable information available about the safety of fish oil when used topically.
CHILDREN: POSSIBLY SAFE
when used orally and appropriately (5708,5711,65732,66070).
In adolescents 9 years of age and older, fish oil providing doses of up to 2250 mg omega-3 fatty acids daily have been used with apparent safety for up to 12 weeks (101543). Fish oil used in enteral feeds for up to 9 months has been shown to be safe in infants (13745). Young children should limit dietary consumption to no more than two ounces of fish per week (12967,12968). ...when given as part of parenteral nutrition in infants receiving long-term parenteral nutrition (96118,110340,110346,110352).
CHILDREN: POSSIBLY UNSAFE
when fish oil from dietary sources are consumed in large amounts.
Fatty fish can contain significant amounts of toxins such as mercury, polychlorinated biphenyls (PCBs), dioxin, and dioxin-related compounds. Frequent consumption of contaminated fish can cause brain damage, mental retardation, blindness, and seizures in children. Lower levels can cause more subtle problems such as learning disabilities (12964). Young children should limit consumption to no more than 2 ounces per week of fish (12967,12968).
PREGNANCY AND LACTATION: LIKELY SAFE
when used orally and appropriately.
Intake of fish oil during pregnancy does not appear to adversely affect the fetus or nursing infant (1026,1027,1042,8706,12969,12970,12971,12972,12973,14397)(15015,15162,101540,110338,113217). The adequate intake level of omega-3 fatty acids during pregnancy is 1.4 grams daily; the adequate intake level during lactation is 1.3 grams daily (89377). If possible, people who are trying to become pregnant, as well as those who are pregnant or lactating, should avoid swordfish, king mackerel, and tilefish (also called golden bass or golden snapper), as these may contain high levels of methylmercury. Pregnant individuals should also limit consumption of other fatty fish to 12 ounces, or about 3-4 servings, per week.
PREGNANCY AND LACTATION: POSSIBLY UNSAFE

Fatty fish can contain significant amounts of toxins such as mercury, polychlorinated biphenyls (PCBs), dioxin, and dioxin-related compounds. If possible, people who are trying to become pregnant, as well as those who are pregnant or lactating, should avoid swordfish, king mackerel, and tilefish (also called golden bass or golden snapper), as these may contain high levels of methylmercury. Pregnant individuals should also limit consumption of other fatty fish to 12 ounces, or about 3-4 servings, per week (12967,12968).
LIKELY SAFE ...when used orally in amounts commonly found in foods. Tagetes has Generally Recognized as Safe (GRAS) status in the US (4912). There is insufficient reliable information available about the safety of tagetes used in amounts greater than those found in foods.
PREGNANCY AND LACTATION:
Insufficient reliable information available; avoid amounts greater than those commonly found in foods.
LIKELY SAFE ...when used orally and appropriately. Selenium appears to be safe when taken short-term in amounts below the tolerable upper intake level (UL) of 400 mcg daily (4844,7830,7831,7836,7841,9724,9797,14447,17510,17511)(17512,17513,17515,17516,97087,97943,109085); however, there is concern that taking selenium long-term might not be safe. Some evidence shows that consuming a diet containing more than the recommended dietary allowance (RDA) of selenium, which is 55 mcg daily for most adults, is associated with an increased risk for developing type 2 diabetes (99661). Some evidence also shows that taking a selenium supplement 200 mcg daily for an average of 3-8 years increases the risk of developing type 2 diabetes (97091,99661). Higher serum levels of selenium are also associated with an increased risk of developing diabetes and increased mortality (16710,99661). ...when used intravenously. Selenium, as selenious acid, is an FDA-approved drug. Sodium selenite intravenous infusions up to 1000 mcg daily have been safely used for up to 28 days (90347,92910).
POSSIBLY UNSAFE ...when used orally in high doses or long-term. Doses above 400 mcg daily can increase the risk of developing selenium toxicity (4844,7825). Additionally, some evidence shows that consuming a diet containing more than the recommended dietary allowance (RDA) of selenium, which is 55 mcg daily for most adults, is associated with an increased risk for developing type 2 diabetes (99661). There is also concern that taking a selenium supplement 200 mcg daily long-term, for an average of 3-8 years, increases the risk of developing type 2 diabetes (99661). Higher serum levels of selenium are also associated with an increased risk of developing diabetes and increased mortality (16710,99661).
CHILDREN: POSSIBLY SAFE
when used orally and appropriately.
Selenium seems to be safe when used short-term in doses below the tolerable upper intake level (UL) of 45 mcg daily for infants up to age 6 months, 60 mcg daily for infants 7 to 12 months, 40-90 mcg daily for children 1 to 3 years, 100-150 mcg daily for children 4 to 8 years, 200-280 mcg daily for children 9 to 13 years, and 400 mcg daily for children age 14 years and older (4844,86095); however, there is some concern that long-term use might not be safe. ...when used via a nasogastric tube in premature infants (7835,9764).
PREGNANCY: POSSIBLY SAFE
when used orally and appropriately.
Selenium appears to be safe when used short-term in amounts that do not exceed the tolerable upper intake level (UL) of 400 mcg daily (4844,17507,74419,74481,74391); however, there is concern that long-term use might not be safe.
PREGNANCY: POSSIBLY UNSAFE
when used orally in excessive doses.
Doses above 400 mcg daily may cause significant toxicity (4844).
LACTATION: POSSIBLY SAFE
when used orally and appropriately.
Selenium appears to be safe when used short-term in amounts that do not exceed the tolerable upper intake level (UL) of 400 mcg daily when taken short-term (4844,74467); however, there is concern that long-term use might not be safe.
LACTATION: POSSIBLY UNSAFE
when used orally in excessive doses.
Doses above 400 mcg daily may cause significant toxicity (4844,7838). ...when used orally in HIV-positive women. Selenium supplementation in HIV-positive women not taking highly active antiretroviral therapy may increase HIV-1 levels in breast milk (90358).
LIKELY SAFE ...when used orally and appropriately in doses of up to 2 mg daily. Zeaxanthin supplements have been safely used in clinical trials at doses of up to 2 mg daily for up to 10 years (94701,94702,94703,108615).
POSSIBLY SAFE ...when used orally and appropriately in amounts greater than 2 mg daily. Zeaxanthin supplements in doses of 8-10 mg daily for up to 12 months have been used with apparent safety in clinical trials (60175,60245).
CHILDREN: POSSIBLY SAFE
when used orally and appropriately.
A specific product containing zeaxanthin (LUTEINofta, SOOFT Italia SpA) has been used with apparent safety in infants at a dose of 0.0006 mg daily for 36 weeks (91163). There is insufficient reliable information available about the safety of zeaxanthin at higher doses or in older children.
PREGNANCY AND LACTATION: LIKELY SAFE
when used orally and appropriately in amounts found in foods.
Zeaxanthin is found in breast milk and levels correlate with infant status (106365). There is insufficient reliable information available about the safety of supplemental zeaxanthin.
Below is general information about the interactions of the known ingredients contained in the product Lutein Vision Advanced. Some ingredients may not be listed. This information does NOT represent a recommendation for or a test of this specific product as a whole.
Fish oil may have antiplatelet effects and may increase the risk of bleeding if used with anticoagulant or antiplatelet drugs. However, evidence is conflicting.
 Details
While fish oil may not be a potent inhibitor of platelet function, high doses of fish oil might have antiplatelet effects. Theoretically, concomitant use of fish oil with anticoagulant or antiplatelet drugs may increase the risk of bleeding (8671,8679,8696,13769,21223,21224,66258). However, the most rigorous research shows that short-term doses of fish oil 10 grams daily or long-term doses of 1.5 grams daily for up to 52 weeks does not increase the risk of bleeding or affect coagulation parameters in chronically ill and vulnerable patients (97180). Other controlled research shows that fish oil does not affect platelet function or increase the risk of bleeding (17990,17996,66105,66267,89374,107180). Some research even suggests that perioperative fish oil use decreases bleeding risk (89352). Some research suggests fish oil does not have additive antiplatelet effects when combined with aspirin (13769), but other clinical evidence suggests that adding fish oil to low-dose aspirin treatment increases antiplatelet effects in patients who are aspirin-resistant (21226). Also, some clinical research seems to show that fish oil has additive antiplatelet effects when used with aspirin and clopidogrel compared to aspirin and clopidogrel alone (21225).

Theoretically, taking fish oil with antihypertensive drugs might increase the risk of hypotension.
Details
|
Theoretically, taking fish oil with contraceptive drugs might decrease the triglyceride-lowering effects of fish oil.
Details
There is some evidence that contraceptive drugs might interfere with the triglyceride lowering effects of fish oils (8694).
|
Taking fish oil with cyclosporine might increase levels and adverse effects of cyclosporine.
Details
In kidney transplant recipients on a general immunosuppressive regimen, taking omega-3 fatty acids daily seems to increase peak blood levels of cyclosporine when compared with placebo. This increase was as much as 20% after one month. However, the area under the curve was not significantly affected (66472).
|
Theoretically, taking fish oil with orlistat might decrease the absorption of fish oil fatty acids.
Details
Orlistat binds lipase in the gastrointestinal tract and reduces fat absorption. Theoretically, taking fish oil with orlistat might decrease absorption of fish oil fatty acids. To avoid this potential interaction, recommend separating administration of orlistat and fish oil by at least 2 hours.
|
Theoretically, taking fish oil with platinum agents can cause resistance to platinum agents, potentially decreasing their effectiveness.
Details
Platinum-induced fatty acids (PIFAs) are fatty acids secreted from human and mouse stem cells when exposed to platinum-based chemotherapy. Animal research suggests that PIFAs cause resistance to chemotherapy by stimulating lysophospholipid production in the spleen, which interferes with the DNA damage caused by certain chemotherapy drugs (92076). One PIFA, known as 16:4(n-3), has been found in both raw fish and some commercially available fish oil products. Mackerel and herring have high PIFA concentrations, while salmon and tuna have low PIFA concentrations. Levels of PIFA in commercial fish oil products ranged from 0.2- 5.7 microMol. Animal research shows that PIFA-containing fish oil products cause resistance to cisplatin, fluorouracil, irinotecan, and oxaliplatin (91250,92075). It is unclear if all commercially available fish oil products contain PIFAs. Additionally, it is argued that levels of PIFA found in some fish oil products are too low to be of clinical concern. Furthermore, a lack of chemotherapy resistance in countries with high fish intake, such as Greenland, Japan, and Norway, suggest that this interaction may not be clinically significant (91288,91289).
|
Taking fish oil with sirolimus might increase levels and adverse effects of sirolimus.
Details
Pharmacokinetic research shows that omega-3 fatty acids increase exposure to sirolimus in kidney transplant patients on a calcineurin inhibitor-free immunosuppressive regimen. A 25% dose reduction in sirolimus was required to keep patients within the expected trough-concentration window (105232). Researchers hypothesize that this may be due to inhibition of cytochrome P450 3A4 (CYP3A4) by fish oil, although this has not been confirmed in clinical research.
|
Taking fish oil with tacrolimus might increase levels and adverse effects of tacrolimus.
Details
In a small group of patients, taking fish oil 2.6 grams (Omacor) daily for 4 weeks increased the 8-hour area under the curve of tacrolimus by 25% when compared with baseline. Peak levels were increased by approximately 22% (105212). Researchers hypothesize that this may be due either to an increase in bioavailability or to inhibition of cytochrome P450 3A4 (CYP3A4) by fish oil, although this has not been confirmed in clinical research.
|
Fish oil may have antiplatelet effects and might increase the risk of bleeding if used with warfarin.
Details
|
Selenium may have antiplatelet effects and may increase the risk of bleeding if used with anticoagulant or antiplatelet drugs.
Details
Clinical research suggests that taking selenium 10 mcg/kg/day can increase bleeding times by increasing prostacyclin production, which inhibits platelet activity (14540). Other clinical research suggests that taking selenium 75 mcg daily, in combination with ascorbic acid 600 mg, alpha-tocopherol 300 mg, and beta-carotene 27 mg, reduces platelet aggregation (74406).
|
Theoretically, selenium might prolong the sedating effects of barbiturates.
Details
|
Contraceptive drugs might increase levels of selenium, although the clinical significance of this effect is unclear.
Details
Some research suggests that oral contraceptives increase serum selenium levels in women taking oral contraceptives; however, other research shows no change in selenium levels (14544,14545,14546,101343). It is suggested that an increase could be due to increased carrier proteins, indicating a redistribution of selenium rather than a change in total body selenium (14545).
|
Gold salts might interfere with selenium activity in tissues.
Details
|
Theoretically, selenium supplementation may reduce the effectiveness of immunosuppressant therapy.
Details
|
Selenium might reduce the beneficial effects of niacin on high-density lipoprotein (HDL) levels.
Details
A combination of niacin and simvastatin (Zocor) effectively raises HDL cholesterol levels in patients with coronary disease and low HDL levels. Clinical research shows that taking a combination of antioxidants (vitamin C, vitamin E, beta-carotene, and selenium) along with niacin and simvastatin (Zocor) attenuates this rise in HDL, specifically the HDL-2 and apolipoprotein A1 fractions, by more than 50% in patients with coronary disease (7388,11537). It is not known whether this adverse effect is due to a single antioxidant such as selenium, or to the combination. It also is not known whether it will occur in other patient populations.
|
Theoretically, selenium might interfere with warfarin activity.
Details
Animal research suggests that selenium can increase warfarin activity. Selenium might interact with warfarin by displacing it from albumin binding sites, reducing its metabolism in the liver, or by decreasing production of vitamin K-dependent clotting factors (14541). Selenium can also prolong bleeding times in humans by increasing prostacyclin production, which inhibits platelet activity (14540).
|
Theoretically, taking zeaxanthin with antidiabetes drugs might increase the risk of hypoglycemia.

Below is general information about the adverse effects of the known ingredients contained in the product Lutein Vision Advanced. Some ingredients may not be listed. This information does NOT represent a recommendation for or a test of this specific product as a whole.
General
...Orally and parenterally, fish oil is generally well-tolerated.
Topically, no adverse effects have been reported. However, a thorough evaluation of safety outcomes has not been conducted.
Most Common Adverse Effects:
Orally: Abdominal pain, bad breath, fishy aftertaste, heartburn, increased low-density lipoprotein (LDL) cholesterol levels, loose stools, nausea, and rash.
Serious Adverse Effects (Rare):
Orally: Atrial fibrillation. When taken in doses of 3 grams or more daily, there are rare reports of increased risk of bleeding and stroke, as well as immune suppression.
Cardiovascular
...Orally, fish oil supplements in doses of 3-10 grams daily can cause a dose-dependent increase in low-density lipoprotein (LDL) cholesterol levels in some people (2299,2318,8678,8698,15734,15735,48120,65729) by increasing the size of LDL particles (9771).
Therefore, LDL levels should be monitored in people who take fish oil supplements (15734). But fish oil doesn't seem to cause development of atherosclerosis, despite earlier concerns that polyunsaturated fatty acids, such as omega-3 fatty acids, might increase the oxidation of LDL (1011,2323,7165,7366,8695,8700,9771).
There is concern that fish oil supplements may be associated with an increased risk for atrial fibrillation (AF), particularly in patients with or at risk for cardiovascular disease (CVD). In one large clinical study (the STRENGTH trial), taking a prescription fish oil product (Epanova) 4 grams daily for up to 5 years was associated with an increased risk for AF, with a number needed to harm of 114 when compared with a corn oil control. The patients in this study were considered to be at high risk for future CVD (103491).
In a secondary analysis of the Omega-3 fatty acids in Elderly patients with Myocardial Infarction (OMEMI) trial, adults aged 70-82 years with recent myocardial infarction supplementing with 1.8 grams daily of n-3 PUFA (EPA/DHA) for 24 months had a 90% increased risk of developing AF or micro-AF, which is characterized by short, AF-like activity lasting less than 30 seconds. Changes in serum EPA levels seem to mediate this risk, with higher serum EPA levels predictive of an increased risk of AF and intermediate serum EPA levels predictive of an increased risk of micro-AF (112469).
Meta-analyses of randomized controlled trials show that taking omega-3 fatty acid supplements increases the incidence rate ratio for AF by up to 37% when compared with placebo, with an increased incidence rate associated with doses of more than 1 gram daily. One study in these analyses used eicosapentaenoic acid (EPA) alone as purified icosapent ethyl (106075,107171,107181).
In 2023, the Pharmacovigilance Risk Assessment Committee (PRAC) of the European Medicines Agency issued a public statement on the use of omega-3-acid ethyl esters, concluding that exposure to omega-3-acid ethyl esters for the treatment of hypertriglyceridemia is associated with a dose-dependent increased risk of AF in patients with established cardiovascular disease or risk factors for cardiovascular disease when compared with placebo. The highest risk of AF is associated with a dose of 4 grams daily. If AF occurs, treatment should be permanently discontinued (112467).
Dermatologic
...Orally, skin rashes, itching, and skin irritation have been reported (66498,66492,66488,89369,104551).
A case of severe tissue inflammation and breast tissue necrosis has been reported for a female who injected fish oil from capsules subcutaneously for breast augmentation (89371).
Gastrointestinal
...Orally, most adverse effects of omega-3 fatty acids are gastrointestinal in nature (12915,65599,65728,65770,65780,65904,66061,66104,66164,66488)(89347,89357,103491,103551,107172).
Gastrointestinal upset is common with the use of fish oil supplements, occurring in up to 5% of patients in clinical trials, with nausea in up to 1.5% of patients (2307,16733,65599,65732,65762,65830,65886,65925,65974)(66020,66042,66083,66104,66130,66164,66169,66358,66370,66488)(66494,66498,89347,103491,104551,110353). Diarrhea and loose stools may also occur (6257,10871,65599,65648,65830,65935,66042,66061,66104,66119)(66130,66173,66492,89347,89359,103491,104551,107172,110353), with potentially severe diarrhea at very high doses (12986,16901,66093,66356). There have also been reports of increased burping (17963,65648,65729,65770,65830,66020,66042,66077,66164,66169)(66492,66494,104551), acid reflux, heartburn (104551,110338), indigestion (65566,65830,66061,66104,66173,89359), abdominal bloating (66083,66104), abdominal or gastrointestinal pain or discomfort (8680,17996,66119,66492,103491), anorexia (62390,89359), flatulence (66492), constipation (16901), nausea and vomiting (65728,65830,66104,66130,66488,103491,104551), steatorrhea (66119,66354,66356), fishy hiccups (66488), metallic taste (66488), and a fishy breath odor and aftertaste (16901,65648,65729,65762,66020,66042,66061,66077,66083,66104)(66130,66164,66172,66173,66424,66488,66494,89369,104551,107172). Also, some preliminary evidence suggests that increased serum levels of omega-3 fatty acids, especially DHA, might increase the risk for atrophic gastritis (8709).
Gastrointestinal side effects may be minimized if fish oils are taken with meals and if doses are started low and gradually increased. Taking supplements with meals or freezing them seems to help decrease these side effects for some patients (12975). Enteric coated fish products might also help reduce side effects (6258).
Hematologic
...Orally, 3 grams or greater of omega-3 fatty acids daily may inhibit platelet aggregation and increase the risk of bleeding; however, there is little evidence of statistically significant bleeding risk at lower doses (1313,8699,66500,66501,66334,101543).
Very large intakes of fish oil or omega-3 fatty acids (more than 46 grams per day) may increase the risk of ischemic or hemorrhagic (bleeding) stroke (7603,66502).
A case of hemolytic anemia has been reported for an infant with short bowel syndrome who developed liver disease from total parenteral nutrition (TPN) and was switched to a specific TPN with fish oil (Omegaven, Fresenius-Kabi, Graz, Austria) instead. After stopping the fish oil-TPN, the anemia was reversed suggesting that parenteral fish oil might cause hemolytic anemia (66022).
Hepatic ...Orally, mild elevations in liver function tests, such as alanine aminotransferase and aspartate aminotransferase, have been reported rarely (66353,113218).
Immunologic
...A case of anaphylaxis following ingestion of a fish oil capsule has been reported for a female patient with a history of allergy to crab.
The patient was treated successfully with epinephrine, but had several recurrences of stridor over the next 2 days (89378).
There is also some evidence that fish oil in doses greater than 3 grams per day might adversely affect immune function. Fish oil appears to suppress T- and B-cell function and to reduce the production of cytokines, which might be detrimental to elderly people and people with suppressed immune function such as patients with human immunodeficiency virus (HIV) infection (1313,7383,7384).
Neurologic/CNS ...Orally, fish oil may cause headache, dizziness, and inability to sleep (65599,65648,89359,103491,104551). Also, restlessness and formication have been reported in less than 1% of studied cases of patients taking fish oil (66498).
Oncologic ...There is some concern that high fish intake may increase the risk for certain types of cancer. One large epidemiological study has found that dietary intake of fish oil from fatty fish twice a week or more is associated with a 16% increased risk of breast cancer when compared with eating fatty fish less than twice weekly (107175). Additionally, an analysis of the NIH-AARP Diet and Health Study, a prospective cohort study in over 491,000 older adults, has found that total intake of fish is associated with increased melanoma risk over a median follow-up of 15.5 years. When the lowest and highest quintiles of intake are compared, there is a 22% increase in the risk for malignant melanoma and a 28% increase in the risk for melanoma in situ. In sub-group analyses, all melanoma incidence is positively associated with tuna intake or non-fried fish intake, but malignant melanoma incidence is inversely associated with fried fish intake (108509). It was suggested that the positive associations could be due to contaminants in fish such as polychlorinated biphenyls, dioxins, arsenic, and mercury.
Pulmonary/Respiratory ...Orally, fish oil has been reported to cause nasopharyngitis and upper respiratory tract infections in 3. 3% of patients in one clinical trial (65798). Exacerbation of asthma and apnea have been reported for patients using fish oil (1040,66061,66119,66354).
Other ...Fish oil can contribute to caloric intake and may cause weight gain if used long-term. One gram of fat or oil provides 9 kcal (6871). Fish oil capsules containing 500 mg omega-3 fatty acids in 1 gram of oil would supply about 13.5 kcal per capsule (6871,6874). Fish oil supplements also contain cholesterol in amounts from 1-6 mg per gram of fish oil (3022,6871).
General
...Orally, ornamental marigold is well tolerated in amounts found in foods.
No adverse effects have been reported when used in amounts greater than those found in foods. A thorough evaluation of safety outcomes has not been conducted. Topically, a thorough evaluation of safety outcomes has not been conducted.
Most Common Adverse Effects:
Topically: Contact dermatitis.
Dermatologic ...Topically, ornamental marigold has been reported to cause contact dermatitis (11).
Immunologic ...Ornamental marigold 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 (11).
General
...Orally, selenium is generally well-tolerated when used in doses that do not exceed the tolerable upper intake level (UL) of 400 mcg daily.
Intravenously, selenium is generally well-tolerated.
Most Common Adverse Effects:
Orally: Gastric discomfort, headache, and rash. Excessive amounts can cause alopecia, dermatitis, fatigue, nail changes, nausea and vomiting, and weight loss.
Serious Adverse Effects (Rare):
Orally: Excessive ingestion has led to cases of multi-organ failure and death.
Dermatologic ...Excess selenium can produce selenosis in humans, affecting liver, skin, nails, and hair (74304,74326,74397,74495,90360) as well as dermatitis (74304). Results from the Nutritional Prevention of Cancer Trial conducted among individuals at high risk of nonmelanoma skin cancer demonstrate that selenium supplementation is ineffective at preventing basal cell carcinoma and that it increases the risk of squamous cell carcinoma and total nonmelanoma skin cancer (10687). Mild skin rash has been reported in patients taking up to 200 mcg of selenium daily for up to 12 months (97943).
Endocrine
...Multiple clinical studies have found an association between increased intake of selenium, either in the diet or as a supplement, and the risk for type 2 diabetes (97091,99661).
One meta-analysis shows that a selenium plasma level of 90 mcg/L or 140 mcg/L is associated with a 50% or 260% increased risk for developing type 2 diabetes, respectively, when compared with plasma levels below 90 mcg/L. Additionally, consuming selenium in amounts exceeding the recommended dietary allowance (RDA) is associated with an increased risk of developing diabetes when compared with consuming less than the RDA daily. Also, taking selenium 200 mcg daily as a supplement is associated with an 11% increased risk for diabetes when compared with a placebo supplement (99661).
Hypothyroidism, secondary to iodine deficiency, has been reported as a result of selenium intravenous administration (14563,14565). One large human clinical trial suggested a possible increased risk of type 2 diabetes mellitus in the selenium group (16707).
Gastrointestinal ...In human research, nausea, vomiting, and liver dysfunction has been reported as a result of high selenium exposure (74439,74376). Mild gastric discomfort has been reported in patients taking up to 200 mcg of selenium daily for up to 12 months (97943).
Genitourinary ...The effect of selenium supplementation on semen parameters is unclear. In human research, selenium supplementation may reduce sperm motility (9729); however, follow-up research reported no effect on sperm motility or any other semen quality parameter (74441).
Neurologic/CNS ...Chronic exposure to organic and inorganic selenium may cause neurotoxicity, particularly motor neuron degeneration, leading to an increased risk of amyotrophic lateral sclerosis (ALS) (74304). Mild headache has been reported in patients taking up to 200 mcg of selenium daily for up to 12 months (97943).
General ...Orally, dietary and supplemental zeaxanthin are generally well tolerated. No adverse effects have been reported in clinical research.
