HelloPharmacist Scorecard of E Mixed Tocopherols by Priority One Nutritional Supplements
Our pharmacy team’s full take, with four database checks built into the cards below — a summary of what is known, not a grade of the product itself.
What’s inside
Full disclosure
This product contains 4 active ingredients, all forms of vitamin E: D-gamma-tocopherol, D-delta-tocopherol, D-beta-tocopherol, and vitamin E itself. These are natural mixed tocopherols—different chemical forms of the same nutrient, each contributing to your body's antioxidant defenses.
The softgel is filled with gelatin, glycerin, and purified water as inactive ingredients to hold and deliver the vitamin E.
Does it work?
Strong evidence
Vitamin E in this form is effective for preventing and treating vitamin E deficiency and ataxia with vitamin E deficiency (AVED), a rare genetic condition. It's possibly effective for Alzheimer disease, beta-thalassemia, glucose-6-phosphate dehydrogenase (G6PD) deficiency, and intracranial hemorrhage, though the evidence is less established in those uses.
How safe is it?
Well-documented data
Vitamin E from food and standard doses is generally well tolerated. However, high-dose long-term supplements raise the risk of bleeding and other harms.
Rare serious side effects include bleeding, hemorrhagic stroke, and cardiovascular complications. There's particular concern about hemorrhagic stroke in male smokers taking synthetic vitamin E over several years, though other studies haven't shown the same risk.
High doses especially increase bleeding risk if you have a vitamin K deficiency or take blood thinners. During pregnancy, stick to the amounts in food and prenatal vitamins, and avoid high-dose supplements unless your doctor directs otherwise.
While breastfeeding, normal dietary amounts are fine, but check with your doctor before taking high-dose supplements.
Meds to double-check
Moderate interaction found
Before taking this product, check with your pharmacist or doctor if you're on blood thinners or blood-clotting medications (anticoagulants or antiplatelets, including warfarin), chemotherapy drugs (especially alkylating agents and antitumor antibiotics), medications processed by your liver's CYP3A4 enzyme, niacin, cyclosporine, or selumetinib (Koselugo). The bleeding risk is the most serious concern—worst Moderate severity.
The bottom line
Scorecard at a glanceFully disclosed formula with clinical evidence supporting its stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.
This supplement makes sense if you have or are at risk for vitamin E deficiency. If you take any blood thinners, are on chemotherapy, or take niacin or cyclosporine, have your pharmacist check this product against your exact medications before you start.
Talk to your doctor about the right dose for you—less is often better when it comes to vitamin E.

E Mixed Tocopherols by Priority One Nutritional Supplements Drug Interactions
HelloPharmacist Interaction Report
E Mixed Tocopherols by Priority One Nutritional Supplements contains vitamin E in several forms, and vitamin E does interact with a number of medications.
The most serious concern is with blood thinners and blood-clotting drugs (anticoagulants and antiplatelets)—vitamin E can increase your bleeding risk by interfering with how your blood clots and reducing platelet function. This effect is dose-dependent and shows up especially at higher doses.
Read the full breakdown — every affected drug type, severity by severity
Vitamin E in this product may also slow how your liver breaks down certain medications processed through a liver enzyme called CYP3A4, potentially changing their levels in your bloodstream. Additionally, it may reduce how well some chemotherapy drugs work—both alkylating agents like cyclophosphamide and antitumor antibiotics like doxorubicin rely on generating free radicals, and vitamin E's antioxidant action could theoretically blunt that effect.
Taking it with niacin (a cholesterol medication) may also weaken niacin's beneficial effects on HDL cholesterol.
There's also a specific concern if you're on cyclosporine (an immune-suppressant), since certain vitamin E formulations can increase how much cyclosporine your body absorbs. And if you're taking selumetinib (Koselugo), adding this supplement could push your total daily vitamin E dose into ranges linked to bleeding risk.
Altogether, these interactions span 754 individual medications. Use the medication checker on this page to look up your exact prescriptions before you start.

For each ingredient in E Mixed Tocopherols with known interactions, here are the types of medications it can affect. Open any type for the detail — or search your exact drug in the checker above.
Vitamin E
Alkylating Agents
Theoretically, antioxidant effects of vitamin E might reduce the effectiveness of alkylating agents.
There's concern that antioxidants could reduce the activity of chemotherapy drugs which generate free radicals, such as cyclophosphamide, chlorambucil, carmustine, busulfan, and thiotepa. 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. 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.
Anticoagulant/Antiplatelet Drugs
Concomitant use of vitamin E and anticoagulant or antiplatelet agents might increase the risk of bleeding.
Vitamin E seems to inhibit of platelet aggregation and antagonize the effects of vitamin K-dependent clotting factors. These effects appear to be dose-dependent, and are probably only likely to be clinically significant with doses of at least 800 units daily. Mixed tocopherols, such as those found in food, might have a greater antiplatelet effect than alpha-tocopherol. RRR alpha-tocopherol (natural vitamin E) 1000 IU daily antagonizes vitamin K-dependent clotting factors. Advise patients to avoid high doses of vitamin E, especially in people with low vitamin K intake or other risk factors for bleeding.
Antitumor Antibiotics
Theoretically, antioxidant effects of vitamin E might reduce the effectiveness of antitumor antibiotics.
There's concern that antioxidants could reduce the activity of antitumor antibiotic drugs such as doxorubicin, which generate free radicals. 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. 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.
Cyclosporine (Neoral, Sandimmune)
A specific form of vitamin E might increase absorption and levels of cyclosporine.
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. However, this interaction is unlikely to occur with the usual forms of vitamin E.
Cytochrome P450 3A4 (Cyp3A4) Substrates
Theoretically, vitamin E might induce metabolism of CYP3A4, possibly reducing the levels CYP3A4 substrates.
Vitamin E appears to bind with the nuclear receptor, pregnane X receptor (PXR), which results in increased expression of CYP3A4. 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.
Selumetinib (Koselugo)
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.
Selumetinib contains 48-54 IU vitamin E per capsule. The increased risk of bleeding with vitamin E appears to be dose-dependent. 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.
Warfarin (Coumadin)
Using vitamin E with warfarin might increase the risk of bleeding.
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,. At a dose of 1000 IU per day, vitamin E can antagonize vitamin K-dependent clotting factors even in people not taking warfarin. 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.
Niacin
Vitamin E might decrease the beneficial effects of niacin on high-density lipoprotein (HDL) cholesterol levels.
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%. Vitamin E alone combined with a statin does not seem to decrease HDL levels. 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.
