Below is general information about the safety of the known ingredients contained in the product Once-Daily Health Booster. 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. Beta-carotene supplements are appropriate for certain specific conditions; however, beta-carotene supplementation is not recommended for the general population (4844,6393). There is no tolerable upper intake level (UL) set for beta-carotene. However, doses as low as 20 mg/day have been associated with increased risk of lung and prostate cancer in people who smoke (1371,3359,3937,3959,6393,11786). There is also concern that taking high doses of antioxidants such as beta-carotene might do more harm than good. In several analyses of clinical studies involving smokers and healthy non-smokers, taking beta-carotene supplements alone or in combination with other antioxidants is associated with an increased risk of mortality from all causes (15305,34514,90775).
POSSIBLY UNSAFE ...when used orally in high doses or in people who smoke or have a history of asbestos exposure. Supplemental beta-carotene 20 mg daily for 5-8 years seems to increase the risk of lung cancer, prostate cancer, intracerebral hemorrhage, and cardiovascular and total mortality in people who smoke cigarettes or have a history of high-level exposure to asbestos (1371,3359,3937,3959,6393,11786,34591). There is also concern that taking high doses of antioxidants such as beta-carotene might do more harm than good in the general population. In several analyses of clinical studies involving smokers and healthy non-smokers, taking beta-carotene supplements alone or in combination with other antioxidants is associated with an increased risk of mortality from all causes (15305,34514,90775). Beta-carotene from foods does not seem to have this effect.
CHILDREN: LIKELY SAFE
when used orally and appropriately (4844).
High doses (greater than 60 mg per day) have been used with apparent safety for specific conditions such as erythropoietic protoporphyria (11793).
PREGNANCY AND LACTATION: LIKELY SAFE
when used orally and appropriately (4844,6393).
There is insufficient reliable information available about the safety of large doses of beta-carotene in pregnancy and lactation.
LIKELY SAFE ...when the flower preparations are used orally or topically and appropriately (4,19779,36931,39503,93552,93557,96647,105088).
PREGNANCY: LIKELY UNSAFE
when used orally; contraindicated due to spermatocide, antiblastocyst, and abortifacient effects.
There is insufficient reliable information available about the safety of calendula when used topically during pregnancy (4).
LACTATION:
Insufficient reliable information available; avoid using.
LIKELY SAFE ...when consumed in the amounts found in foods. Chlorophyllin is permitted for use as a coloring agent in limited quantities in foods (5630).
POSSIBLY SAFE ...when used orally, short-term. Chlorophyllin has been used with apparent safety at a dose of up to 300 mg daily for up to 3 months (1321,1323,41847,41839,101244). There is insufficient reliable information available about the safety of chlorophyllin when used orally, long-term. Most chlorophyllin supplements contain copper in concentrations of around 4%, or 4 mg copper per 100 mg chlorophyllin (105553). The tolerable upper intake level for copper in adults is 10 mg daily, with an average dietary intake in the United States of approximately 1-1.5 mg daily. Long-term consumption of high levels of copper can lead to serious adverse effects (7135). The bioavailability of copper from chlorophyllin is unclear; until more is known, use with caution. There is insufficient reliable information available about the safety of chlorophyllin when used topically.
CHILDREN:
There is insufficient reliable information available about the safety of chlorophyllin in children.
However, most chlorophyllin supplements contain copper in concentrations of around 4%, or 4 mg copper per 100 mg chlorophyllin (105553). The tolerable upper intake level (UL) for copper by age is 1 mg daily for children 1-3 years, 3 mg daily for children 4-8 years, 5 mg daily for children 9-13 years, and 8 mg daily for adolescents (7135). The bioavailability of copper from chlorophyllin is unclear; until more is known, use with caution.
PREGNANCY AND LACTATION:
Insufficient reliable information available; avoid using.
LIKELY SAFE ...when used orally and appropriately. Consuming up to 20 mg of lutein daily from both dietary and supplemental sources appears to be safe (3219,3220,60167). Lutein supplements have been safely used in clinical trials at doses of up to 20 mg daily for up to 10 years (11798,60133,60177,94703,94701,100986,104570,107107,108615,109763).
CHILDREN: LIKELY SAFE
when used orally and appropriately.
A specific product containing lutein (LUTEINofta, SOOFT Italia SpA) has been used with apparent safety in infants at a dose of 0.14 mg daily for 36 weeks (91163).
PREGNANCY AND LACTATION: LIKELY SAFE
when used orally and appropriately in amounts found in foods.
The high end of dietary lutein intake ranges from 6.9-11.7 mg/day (3219,3220).
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 in amounts commonly found in foods. Saffron has Generally Recognized as Safe (GRAS) status in the US for use as a spice or food coloring agent (4912).
POSSIBLY SAFE ...when used orally and appropriately in larger amounts, short-term. Saffron extracts have been used with apparent safety in clinical trials at doses of up to 100 mg daily for up to 26 weeks (11024,13103,16555,17214,17401,18102,93395,93397,93400,93403)(93407,97359,99436,100135,100138,100140,100658,100659). The saffron constituent crocin has been used with apparent safety at a dose of up to 30 mg daily for up to 3 months (93410,100139,105616).
POSSIBLY UNSAFE ...when used orally in high doses or for longer than 26 weeks. Taking 5 grams or more of saffron can cause severe side effects. Doses of 12-20 grams can be lethal (12,18). There is insufficient reliable information available about the safety of saffron when used topically.
PREGNANCY: LIKELY UNSAFE
when used orally in amounts exceeding those commonly found in foods.
Larger amounts of saffron have uterine stimulant and abortifacient effects (18); avoid using.
LACTATION:
Insufficient reliable information available; avoid using.
POSSIBLY SAFE ...when used orally and appropriately. Tocotrienols have been used with apparent safety at doses of up to 600 mg daily for up to 18 months (99690,99695,99696,104427,104428,112286). Tocotrienols have also been used with apparent safety at a dose of 200 mg daily for up to 5 years (99697). There is insufficient reliable information available about the safety of tocotrienols when applied topically.
PREGNANCY AND LACTATION:
Insufficient reliable information available; avoid using.
LIKELY SAFE ...when used orally or topically and appropriately. Vitamin E is generally considered safe, even at doses exceeding the recommended dietary allowance (RDA); however, adverse effects are more likely to occur with higher doses. The tolerable upper intake level (UL) in healthy people is 1000 mg daily, equivalent to 1100 IU of synthetic vitamin E (all-rac-alpha-tocopherol) or 1500 IU of natural vitamin E (RRR-alpha-tocopherol) (4668,4681,4713,4714,4844,89234,90067,90069,90072,19206)(63244,97075). Although there is some concern that taking vitamin E in doses of 400 IU (form unspecified) per day or higher might increase the risk of adverse outcomes and mortality from all causes (12212,13036,15305,16709,83339), most of this evidence comes from studies that included middle-aged or older patients with chronic diseases or patients from developing countries in which nutritional deficiencies are prevalent.
POSSIBLY UNSAFE ...when used orally in high doses. Repeated doses exceeding the tolerable upper intake level (UL) of 1000 mg daily are associated with significant side effects in otherwise healthy people (4844). ...when used intravenously in large doses. Large repeated intravenous doses of all-rac-alpha-tocopherol (synthetic vitamin E) were associated with decreased activity of clotting factors and bleeding in one report (3074). ...when inhaled. E-cigarette, or vaping, product-use associated lung injury (EVALI) has occurred among adults who use e-cigarette, or vaping, products, which often contain vitamin E acetate. In some cases, this has resulted in death. The majority of patients with EVALI reported using tetrahydrocannabinol (THC)-containing products in the 3 months prior to the development of symptoms. Vitamin E acetate has been detected in most bronchoalveolar lavage samples taken from patients with EVALI. Other ingredients, including THC or nicotine, were also commonly found in samples. However, priority toxicants including medium chain triglyceride (MCT) oil, plant oil, petroleum distillate, or terpenes, were undetectable in almost all samples. While this association shows a correlation between vitamin E acetate inhalation and lung injury, a causal link has not yet been determined, and it is not clear if other toxic compounds are also involved (101061,101062,102970).
CHILDREN: LIKELY SAFE
when used orally and appropriately.
Vitamin E has been safely used in children in amounts below the tolerable upper intake level (UL). The UL for healthy children is: 200 mg in children aged 1-3 years, 300 mg in children aged 4-8 years, 600 mg in children aged 9-13 years, and 800 mg in children aged 14-18 years. A UL has not been established for infants up to 12 months of age (23388).
CHILDREN: POSSIBLY UNSAFE
when used orally in doses above the UL due to increased risk of adverse effects (23388).
...when alpha-tocopherol is used intravenously in large doses in premature infants. Large intravenous doses of vitamin E are associated with an increased risk of necrotizing enterocolitis and sepsis in this population (85062,85083). ...when inhaled. E-cigarette, or vaping, product-use associated lung injury (EVALI) has occurred among adolescents and teenagers who use e-cigarette, or vaping, products. In some cases, this has resulted in death. The majority of patients with EVALI reported using tetrahydrocannabinol (THC)-containing products in the 3 months prior to the development of symptoms. Constituents in E-cigarette or vaping products with the potential to cause lung injury or impaired lung function include lipids, such as vitamin E acetate. Vitamin E acetate has been detected in all bronchoalveolar lavage samples taken from patients with EVALI. No other ingredient, including THC or nicotine, was found in all samples, and other ingredients, including medium chain triglyceride (MCT) oil, plant oil, petroleum distillate, or terpenes, were undetectable This shows that vitamin E acetate is at the primary site of lung injury. A causal link has not yet been described and it is not clear if other compounds are also involved (101061,101062).
PREGNANCY: POSSIBLY SAFE
when used orally and appropriately.
The tolerable upper intake level (UL) during pregnancy is 800 mg for those 14-18 years of age and 1000 mg for those 19 years and older. However, maternal supplementation is not generally recommended unless dietary vitamin E falls below the RDA (4260). No serious adverse effects were reported with oral intake of 400 IU per day starting at weeks 9-22 of pregnancy in healthy patients or those at high risk for pre-eclampsia (3236,97075), or with 600-900 IU daily during the last two months of pregnancy (4260). However, some preliminary evidence suggests that taking vitamin E supplements might be harmful when taken in early pregnancy. A case-control study found that taking a vitamin E supplement during the first 8 weeks of pregnancy is associated with a 1.7-9-fold increase in odds of congenital heart defects (16823). However, the exact amount of vitamin E consumed during pregnancy in this study is unclear. Until more is known, advise patients to avoid taking a vitamin E supplement in early pregnancy unless needed for an appropriate medical indication.
LACTATION: LIKELY SAFE
when used orally in amounts that do not exceed the tolerable upper intake level (UL).
The UL during lactation is 800 mg for those 14-18 years of age and 1000 mg for those 19 years and older (4844).
LACTATION: POSSIBLY UNSAFE
when used orally in amounts that exceed the UL due to increased risk of adverse effects (4844).
LIKELY SAFE ...when vitamin K1 (phytonadione) or vitamin K2 (menaquinone) is used orally and appropriately. A tolerable upper intake level for vitamin K in adults has not been set, because no adverse effects have been noted at a wide range of studied doses. For example, Vitamin K1 up to 10 mg daily and vitamin K2 up to 45 mg daily have been safely used in clinical trials lasting up to 2 years. (54,55,58,6799,7135,14364). Notably, some of these studied doses are exponentially higher than various recommendations for daily adequate intake. See Dosing & Administration and Effectiveness sections for additional information...when vitamin K1 (phytonadione) is used parenterally and appropriately. Vitamin K1 (phytonadione) in oral and injectable form is an FDA-approved drug (7135).
POSSIBLY SAFE ...when vitamin K1 (phytonadione) 0. 1% is used topically in a cream or ointment for up to 12 weeks (91455,103919).
CHILDREN: LIKELY SAFE
when vitamin K1 (phytonadione) is used orally or parenterally and appropriately.
Vitamin K1 (phytonadione) in oral and injectable form is FDA approved for use in children. A tolerable upper intake level for vitamin K in children has not been set (7135).
PREGNANCY AND LACTATION: LIKELY SAFE
when used orally in amounts that do not exceed the daily adequate intake level (AI).
A tolerable upper intake level for vitamin K in pregnancy and lactation has not been set (7135).
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 Once-Daily Health Booster. Some ingredients may not be listed. This information does NOT represent a recommendation for or a test of this specific product as a whole.
Beta-carotene might decrease the beneficial effects of niacin on high-density lipoprotein (HDL) cholesterol levels.
 Details
A combination of niacin and simvastatin (Zocor) effectively raises high-density lipoprotein (HDL) cholesterol levels in patients with coronary disease and low HDL levels. Clinical research shows that taking a combination of antioxidants (beta-carotene, vitamin C, vitamin E, and selenium) along with niacin and simvastatin 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 beta-carotene, or to the combination. It also is not known whether it will occur in other patient populations.

Theoretically, calendula might have additive effects when used with CNS depressants, although this appears to be unlikely.
Details
|
Theoretically, concomitant use of chlorophyllin with photosensitizing drugs may have additive effects.
Details
|
Theoretically, concomitant use of saffron with antidiabetes drugs might increase the risk of hypoglycemia.
Details
|
Theoretically, concomitant use of saffron with antihypertensive drugs might have additive effects.
Details
|
Theoretically, saffron might inhibit the metabolism of caffeine.
Details
A small clinical study suggests that taking saffron powder 300 mg in 150 mL water daily for 5 days and then taking caffeine 200 mg seems to reduce caffeine metabolite levels in the saliva and urine in males, but not females. Theoretically, this may be due to the inhibition of cytochrome P450 1A2 by saffron (100130).
|
Theoretically, concomitant use of saffron and CNS depressants might have additive sedative effects.
Details
|
Concomitant use of tocotrienols with anticoagulant or antiplatelet agents might increase the risk of bleeding. However, this has not been reported in humans.
Details
Taking tocotrienols orally inhibits experimentally-induced platelet aggregation in humans (3237,104429). Theoretically tocotrienols might increase the risk of bleeding if taken with antiplatelet or anticoagulant drugs. However, tocotrienols 400-800 mg daily have been used with aspirin and/or clopidogrel for 1 year with no clear cumulative antiplatelet effects and no reports of bleeding (104429).
|
Theoretically, antioxidant effects of vitamin E might reduce the effectiveness of alkylating agents.
Details
There's concern that antioxidants could reduce the activity of chemotherapy drugs which generate free radicals, such as cyclophosphamide, chlorambucil, carmustine, busulfan, and thiotepa (391). However, some researchers theorize that antioxidants might make chemotherapy more effective by reducing oxidative stress that might interfere with apoptosis (cell death) of cancer cells (14012,14013). More evidence is needed to determine what effect, if any, antioxidants such as vitamin E have on chemotherapy. Advise patients to consult their oncologist before using vitamin E supplements, especially in high doses.
|
Concomitant use of vitamin E and anticoagulant or antiplatelet agents might increase the risk of bleeding.
Details
Vitamin E seems to inhibit of platelet aggregation and antagonize the effects of vitamin K-dependent clotting factors (4733,4844,11580,11582,11583,11584,11586,112162). These effects appear to be dose-dependent, and are probably only likely to be clinically significant with doses of at least 800 units daily (11582,11585). Mixed tocopherols, such as those found in food, might have a greater antiplatelet effect than alpha-tocopherol (10364). RRR alpha-tocopherol (natural vitamin E) 1000 IU daily antagonizes vitamin K-dependent clotting factors (11999). Advise patients to avoid high doses of vitamin E, especially in people with low vitamin K intake or other risk factors for bleeding.
|
Theoretically, antioxidant effects of vitamin E might reduce the effectiveness of antitumor antibiotics.
Details
There's concern that antioxidants could reduce the activity of antitumor antibiotic drugs such as doxorubicin, which generate free radicals (391). However, some researchers theorize that antioxidants might make chemotherapy more effective by reducing oxidative stress that might interfere with apoptosis (cell death) of cancer cells (14012,14013). More evidence is needed to determine what effect, if any, antioxidants such as vitamin E have on chemotherapy involving antitumor antibiotics. Advise patients to consult their oncologist before using vitamin E supplements, especially in high doses.
|
A specific form of vitamin E might increase absorption and levels of cyclosporine.
Details
There is some evidence that one specific formulation of vitamin E (D-alpha-tocopheryl-polyethylene glycol-1000 succinate, TPGS, tocophersolan, Liqui-E) might increase absorption of cyclosporine. This vitamin E formulation forms micelles which seems to increase absorption of cyclosporine by 40% to 72% in some patients (624,625,10368). However, this interaction is unlikely to occur with the usual forms of vitamin E.
|
Theoretically, vitamin E might induce metabolism of CYP3A4, possibly reducing the levels CYP3A4 substrates.
Details
Vitamin E appears to bind with the nuclear receptor, pregnane X receptor (PXR), which results in increased expression of CYP3A4 (13499,13500). Although the clinical significance of this is not known, use caution when considering concomitant use of vitamin E and other drugs affected by these enzymes.
|
Vitamin E might decrease the beneficial effects of niacin on high-density lipoprotein (HDL) cholesterol levels.
Details
A combination of niacin and simvastatin (Zocor) effectively raises high-density lipoprotein (HDL) cholesterol levels in people 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% (7388,11537). Vitamin E alone combined with a statin does not seem to decrease HDL levels (11286,11287). It is not known whether the adverse effect on HDL is due to one of the other antioxidants or to the combination. It also is not known whether it will occur in other patient populations.
|
Taking selumetinib with vitamin E can result in a total daily dose of vitamin E that exceeds safe limits and therefore might increase the risk of bleeding.
Details
Selumetinib contains 48-54 IU vitamin E per capsule (102971). The increased risk of bleeding with vitamin E appears to be dose-dependent (11582,11585,34577). Be cautious when using selumetinib in combination with supplemental vitamin E, especially in patients at higher risk of bleed, such as those with chronic conditions and those taking antiplatelet drugs (102971).
|
Using vitamin E with warfarin might increase the risk of bleeding.
Details
Due to interference with production of vitamin K-dependent clotting factors, use of more than 400 IU of vitamin E daily with warfarin might increase prothrombin time (PT), INR, and the risk of bleeding, (91,92,93). At a dose of 1000 IU per day, vitamin E can antagonize vitamin K-dependent clotting factors even in people not taking warfarin (11999). Limited clinical evidence suggests that doses up to 1200 IU daily may be used safely by patients taking warfarin, but this may not be applicable in all patient populations (90).
|
Vitamin K can antagonize and reverse the therapeutic effects of warfarin.
Details
|
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 Once-Daily Health Booster. 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, beta-carotene is well-tolerated when used in appropriate amounts.
Most Common Adverse Effects:
Orally: Belching, orange skin (temporary).
Serious Adverse Effects (Rare):
Orally: Increased cardiovascular mortality and cancer risk in smokers and other specific patient populations.
Cardiovascular ...Orally, beta-carotene 20 to 30 mg daily seems to increase cardiovascular mortality by 12% to 26% in people who smoke (2642,3949,108641). Smokers and people with a history of asbestos exposure should not use beta-carotene supplements. In males who smoke and have had a prior myocardial infarction (MI), the risk of fatal coronary heart disease increases by as much as 43% with beta-carotene 20 mg daily (3937). These adverse effects do not seem to occur in people who eat foods high in beta-carotene content (1440,2657).
Dermatologic ...High oral doses of beta-carotene in foods or supplements can cause yellow or orange skin pigmentation called carotenoderma (11786,34572,34594,91382,108641). In clinical trials, the incidence of carotenoderma has been reported to be up to 15.8% (34626).
Gastrointestinal ...Orally, beta-carotene may cause belching (34572,34594).
Ocular/Otic ...In a case report, treatment with a high dose of beta-carotene and canthaxanthin for more than 6 years resulted in the development of glistening bright yellow crystalline deposits around the maculae. This resulted in a slight decrease in visual acuity and adaptation to the dark (34641).
Oncologic ...Smokers and people with a history of asbestos exposure should not use beta-carotene supplements. Beta-carotene in doses of 20 mg per day for 5-8 years has been associated with an increased risk of lung and prostate cancer and increased total mortality in people who smoke cigarettes (21 or more daily), and in people with a history of high-level asbestos exposure (3959,6393,11303,11786,104467,108641). These adverse effects do not seem to occur in people who eat foods high in beta-carotene content (1440,2657). There is also concern that beta-carotene might increase the risk of adverse outcomes in non-smokers. In one large-scale population study, males who took a multivitamin more than 7 times per week and who also took a separate beta-carotene supplement had a significantly increased risk of developing advanced prostate cancer (15607).
Pulmonary/Respiratory ...Clinical research shows that taking beta-carotene 20 mg daily, alone or along with vitamin E 50 mg daily, increases the risk of common colds by 21% to 25% in individuals participating in heavy exercise at leisure. However, it does not appear to affect the risk of common cold in individuals who participate in heavy activity at work (34508).
Other ...Analysis of studies in smokers and non-smokers suggests that taking beta-carotene supplements alone or in combination with other antioxidants increases the risk of mortality from all causes (15305).
General
...Orally and topically, calendula is generally well tolerated.
Serious Adverse Effects (Rare):
All ROAs: Allergic reactions.
Dermatologic ...Topically, a preparation containing calendula powder 0. 1% resulted in inflammation around the wound to which it was applied (96647). Burning sensation, itching, redness, and scaling were reported rarely in patients applying a combination of calendula, licorice, and snail secretion filtrate to the face. The specific role of calendula is unclear (110322).
Immunologic ...Orally, calendula can cause allergic reactions. Topically, calendula can cause eczematous allergic reactions. Calendula-specific patch testing is recommended prior to usage to determine allergenic potential. Testing is particularly necessary in individuals sensitive to the Asteraceae/Compositae family (10691,11458,96647). Members of this family include ragweed, chrysanthemums, marigolds, daisies, and many other herbs. A preparation containing calendula powder 0.1% resulted in hives in a patient with a ragweed allergy (96647). Despite the widespread use of calendula and the occurrence of allergies to other family members, there has been only one report of anaphylaxis (11152).
General ...Orally, chlorophyllin seems to be well tolerated when used for up to 3 months. However, a thorough evaluation of safety outcomes has not been conducted.
Dermatologic ...Since chlorophyllin is a semi-synthetic derivative of chlorophyll, there is some concern that it could cause similar adverse effects. Topically, chlorophyll cream has been reported to cause dermatitis (41912). Orally, chlorophyll can cause photosensitization (1326). In case reports, oral consumption of chlorophyll has been associated with the development of pseudoporphyria. Two females developed easily traumatized blisters on their hands after consumption of a Swisse Chlorophyll drink (93892). In one case series, four males developed skin blisters and skin erosions after taking oral chlorophyll 100-1200 mg daily for 6.5 months up to 7 years. Resolution of symptoms was delayed for 2-8 months after chlorophyll discontinuation (97933). To date, chlorophyllin has not been reported to cause similar adverse effects; however, in vitro toxicology research suggests that chlorophyllin is phototoxic (101235).
General ...Orally, dietary and supplemental lutein is generally well tolerated. Doses up to 20 mg daily have not resulted in adverse effects.
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, saffron extract seems to be generally well tolerated.
Most Common Adverse Effects:
Orally: Gastrointestinal complaints, nausea, sedation, vomiting.
Serious Adverse Effects (Rare):
Orally: Anaphylaxis.
Dermatologic ...Orally, sweating and flushing have been reported in clinical research for patients taking saffron 30-60 mg daily (93402,93409). Saffron poisoning can occur with oral intake of doses of 5 grams or more and symptoms include yellow appearance of the skin (2,11).
Gastrointestinal ...Orally, saffron has been associated with changes in appetite, nausea, and vomiting when given at doses of 30 mg twice daily for 26 weeks, or when the saffron constituent crocin was given as 15 mg twice daily for 12 weeks (18102,105616). At lower doses of 30 mg daily, the occurrence rate of these and other adverse events such as dry mouth, dyspepsia, diarrhea, and constipation was rare or similar to placebo (13103,93395,93402,93409). Saffron poisoning can occur with oral intake of doses of 5 grams or more and symptoms include yellow appearance of the mucous membranes (mimicking icterus), vomiting, and bloody diarrhea (2,11).
Genitourinary
...One report of excessive uterine bleeding occurred in a clinical trial.
The patient was taking the saffron constituent crocin 15 mg twice daily. It is unclear whether this event was related to treatment with the saffron constituent (93410).
Saffron poisoning can occur with oral intake of doses of 5 grams or more; symptoms include bleeding from the uterus (2,11).
Hematologic
...Orally, saffron extract has been reported to cause decreases in platelet, white blood cell, and red blood cell counts after 7 days to 12 weeks of use with doses of 60-200 mg daily.
Many of these decreases were only significant when compared to baseline but did not maintain significance when compared to placebo. These reductions were not considered clinically significant (18102,72473,93403,93409).
Saffron poisoning can occur with oral intake of doses of 5 grams or more; symptoms include bloody diarrhea, hematuria, bleeding from the nose, lips, eyelids or uterus, and thrombocytopenic purpura (2,11).
Immunologic ...Allergy to oral saffron has been reported in clinical trials (93404). Anaphylactic reactions can occur within minutes of eating food prepared with saffron (4107,72555). Occupational exposure to saffron has been associated with the development of rhinoconjunctivitis and allergy-induced asthma (4106).
Neurologic/CNS ...Orally, saffron has been reported to cause drowsiness, headache, agitation, and sedation when given at doses of 30 mg twice daily for up to 26 weeks or when crocin is given as 15 mg twice daily for 12 weeks (18102,105616). At doses of 30 mg daily for 6 weeks, the side effect occurrence rate was similar to placebo (13103). Saffron poisoning can occur with oral intake of doses of 5 grams or more; symptoms include vertigo and numbness (2,11).
Ocular/Otic ...Orally, saffron poisoning with oral intake of doses of 5 grams or more can cause ocular symptoms such as yellow appearance of the sclera (2,11).
Psychiatric ...Orally, saffron has been reported to cause anxiety and hypomania when given at doses of 30 mg twice daily for 26 weeks (18102). At doses of 30 mg daily for 6 weeks, the occurrence rate was similar to placebo (13103,93395). One report of agitation occurred in a clinical trial. The patient was taking the saffron constituent crocin 15 mg twice daily. It is unclear whether this event was related to treatment with the saffron constituent (93410).
Renal ...Orally, the saffron constituent crocin given as 15 mg twice daily for 12 week was associated with one case of urinary incontinence (105616). Saffron poisoning can occur with oral intake of doses of 5 grams or more; symptoms include hematuria and uremic collapse (2,11).
General
...Orally, tocotrienols appear to be well-tolerated.
No adverse effects have been reported in clinical trials.
Most Common Adverse Effects:
Topically: Mild itching.
Dermatologic ...Topically, a cream containing 5% tocotrienols has been reported to cause mild itching in 7% of patients in one clinical study (99699). Contact dermatitis has been reported in 33% of patients using a cream containing vitamin E as a mixture of tocopherols and tocotrienols (4721). However, it is unclear if this effect resulted from tocopherols, tocotrienols, or the combination.
General
...Orally and topically, vitamin E is generally well-tolerated.
Serious Adverse Effects (Rare):
Orally: Bleeding, hemorrhagic stroke, cardiovascular complications.
Inhaled: Vitamin E acetate is thought to be responsible for e-cigarette, or vaping, product-use associated lung injury (EVALI).
Cardiovascular
...Some evidence suggests that taking vitamin E supplements, especially greater than or equal to 400 IU taken by mouth daily for over one year, might also increase the risk of mortality in non-healthy patients (12212,13036,15305,16709,83339).
A population study shows that vitamin E use is associated with a significantly increased risk of mortality in people with a history of severe cardiovascular disease such as stroke or myocardial infarction (16709). In an analysis of clinical trials, patients who took either all-rac-alpha-tocopherol (synthetic vitamin E) or RRR-alpha-tocopherol (natural vitamin E) in doses of 400 IU/day or higher had an increased risk of mortality from all causes. The risk of mortality seems to increase when higher doses are used (12212). A large-scale study also suggests that patients with diabetes or cardiovascular disease who take RRR-alpha-tocopherol (natural vitamin E) 400 IU daily have an increased risk of heart failure and heart failure-related hospitalization (13036). However, in another large scale study, taking 600 IU vitamin E every other day for 10 years did not increase the risk of heart failure in healthy females over 45 years of age (90068). There is speculation that high-dose vitamin E might disrupt the normal antioxidant balance and result in pro-oxidant rather than antioxidant effects.
There is some evidence that vitamin E in combination with simvastatin (Zocor), niacin, selenium, vitamin C, and beta-carotene might lower high density lipoprotein-2 (HDL-2) by 15%. HDL-2 is considered to be the most cardioprotective component of HDL (7388). However, vitamin E and a statin alone don't seem to negatively affect HDL (11286,11287). In addition, vitamin E has been associated with increased triglycerides (85215). Although only certain isomers of vitamin E are included for determination of dietary requirements, all isomers are considered for determining safe intake levels. All the isomers are thought to potentially contribute to toxicity.
Dermatologic
...Topically, vitamin E has been associated with contact dermatitis, inflammatory reactions, and eczematous lesions (11998,85066,85285).
Dermatitis, often associated with moisturizers containing vitamin E, has a scattered generalized distribution, is more common on the face than the hands, and is more common in females with a history of atopic dermatitis. In a retrospective analysis of results of patch tests for DL-alpha-tocopherol sensitivity, 0.9% of patients had a definite positive reaction, while over 50% had a weakly positive, non-vesicular erythematous reaction (107869).
Orally, vitamin E has been associated with pruritus in one clinical trial (34596).
Subcutaneously, vitamin E has been associated with reports of lipogranuloma (85188,112331). In one case, subcutaneous injection of a specific supplement (1Super Extenze), containing mineral oil and tocopherol acetate, into the penile tissue resulted in penile disfigurement due to sclerosing lipogranuloma (85188). In another case, a 50-year-old Iranian female presented with lipogranuloma of the face, characterized by severe facial erythema, edema, and tenderness, 3 months after receiving subcutaneous injections of vitamin E to the cheeks for "facial rejuvenation." The patient had noticed initial symptoms within 3 days, and her symptoms progressively worsened over time (112331).
Gastrointestinal ...Orally, vitamin E supplementation has been associated with abdominal pain, nausea, diarrhea, or flu-like symptoms (85040,85323). Intravenously, large doses of vitamin E in premature infants are associated with an increased risk of necrotizing enterocolitis and sepsis (85083,85231).
Genitourinary ...There is contradictory evidence about the effect of vitamin E on prostate cancer risk. One large-scale population study shows that males who take a multivitamin more than 7 times per week and who also take a separate vitamin E supplement have a significantly increased risk of developing prostate cancer (15607). In a large-scale clinical trial (The SELECT trial) in males over the age of 50 years, taking all-rac-alpha-tocopherol (synthetic vitamin E) 400 IU daily increased the risk of developing prostate cancer by 17% when compared with placebo. However, the difference in prostate cancer risk between vitamin E and placebo became significant only 3 years after patients stopped taking supplementation and were followed in an unblinded fashion. Interestingly, patients taking vitamin E plus selenium did not have a significantly increased risk of prostate cancer (17688).
Hematologic ...High doses of vitamin E might increase the risk of bleeding due to antagonism of vitamin K-dependent clotting factors and platelet aggregation. Patients with vitamin K deficiencies or taking anticoagulant or antiplatelet drugs are at a greater risk for bleeding (4098,4844,11999,34596,34538,34626,34594,112162).
Neurologic/CNS ...There is concern that vitamin E might increase the risk of hemorrhagic stroke (16708,34594,34596,108641). In one clinical study, there was a higher incidence of hemorrhagic stroke in male smokers taking all-rac-alpha-tocopherol (synthetic vitamin E) for 5-8 years compared to those not taking vitamin E (3949). Other studies lasting from 1.4-4.5 years and using either all-rac-alpha-tocopherol (synthetic vitamin E) or RRR-alpha-tocopherol (natural vitamin E) showed no significantly increased risk for stroke (2307,3896,3936). A meta-analysis of studies shows that vitamin E in doses of 300-800 IU daily, including both natural and synthetic forms, does not significantly affect total stroke risk. However, it significantly increases the risk of hemorrhagic stroke by 22%. This means that there will be one additional hemorrhagic stroke for every 1250 patients taking vitamin E. In contrast to this finding, the analysis also found that vitamin E significantly reduces the risk of ischemic stroke by 10%. This means that one ischemic stroke will be prevented for every 476 patients taking vitamin E (14621). In patients with moderately severe Alzheimer disease, taking vitamin E 2000 IU for 2 years has been associated with a modest, but significant, increase in falls and episodes of syncope when compared to placebo (4635).
Pulmonary/Respiratory ...When inhaled, vitamin E acetate is thought to play a role in the development of e-cigarette, or vaping, product-use associated lung injury (EVALI). Although a causal link has not yet been determined, in two case series, vitamin E acetate has been found in most bronchoalveolar lavage samples taken from the primary site of lung injury in patients with EVALI, whereas no vitamin E was found in healthy control samples. Other ingredients, including THC or nicotine, were also commonly found in samples. However, priority toxicants including medium chain triglyceride (MCT) oil, plant oil, petroleum distillate, or terpenes, were undetectable in almost all samples. EVALI has resulted in death in some patients (101062,102970).
Other ...In an analysis of 3 trials, taking vitamin E 400 IU with vitamin C 1000 mg daily for 14-22 weeks during gestation appears to increase the risk of gestational hypertension by 30% compared to placebo in patients at risk of pre-eclampsia. However, the risk of pre-eclampsia itself was not increased (83450).
General
...Orally, vitamin K is generally well tolerated.
Most Common Adverse Effects:
Orally: Diarrhea, nausea, and stomach upset.
Serious Adverse Effects (Rare):
Intravenously: There have been rare cases of anaphylaxis and hyperbilirubinemia (in infants).
Dermatologic ...Orally, intake of vitamin K2 (menaquinone) along with calcium and vitamin D3 can cause an increased incidence of skin and skin appendage lesions compared to taking calcium and vitamin D3 alone. However, the risk of this adverse event is low, with 0.5 incidences per 100 patient-years occurring for patients treated with vitamin K, calcium, and vitamin D3 and 0.1 incidences per 100 patient-years occurring for patients treated with calcium and vitamin D3 alone (85467).
Gastrointestinal ...Orally, vitamin K can cause mild to moderate gastrointestinal side effects (91450,91451). The most common effects include nausea, abdominal pain, and diarrhea (91450,91451).
Hepatic ...Orally, vitamin K3 (menadione) has been linked to hepatotoxicity. Vitamin K3 is no longer used therapeutically in North America because it has been linked to hepatic toxicity and jaundice in animal research (7135).
Other ...Intravenously, vitamin K can cause reactions that resemble hypersensitivity or anaphylaxis (85389). These reactions are rare. It is unclear whether the adverse effect is caused by the drug or a component of the solution. There have been very rare cases of hyperbilirubinemia, particularly in premature neonates, following large doses of vitamin K (15). One clinical study in premature infants shows that intramuscular administration of vitamin K 1.0 mg increases bilirubin levels and the duration of phototherapy when compared with vitamin K 0.3 mg and 0.5 mg. However, the clinical relevance of these findings is unclear, as no differences in bilirubin-induced neurologic dysfunction were reported (112100).
General ...Orally, dietary and supplemental zeaxanthin are generally well tolerated. No adverse effects have been reported in clinical research.
