HelloPharmacist Scorecard of Vitamin E 268 mg by Solaray
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 2 active ingredients: vitamin E and mixed tocopherols — all forms of the same essential nutrient. Vitamin E is a fat-soluble antioxidant that your body needs to protect cells and keep your immune system working.
The softgel also contains soybean oil, gelatin, and glycerin as inactive ingredients to deliver the vitamin.
Does it work?
Moderate evidence
Vitamin E is effective for treating vitamin E deficiency and a rare genetic condition called ataxia with vitamin E deficiency (AVED). The evidence is less solid for other uses — it's possibly effective for Alzheimer disease, beta-thalassemia, G6PD deficiency, and intracranial hemorrhage, but we don't have strong proof it works for these yet.
How safe is it?
Well-documented data
Vitamin E from food and normal dietary amounts is generally well tolerated. High-dose long-term supplements, though, may raise your bleeding risk and carry other harms.
In rare cases, high doses have been tied to serious bleeding and hemorrhagic stroke (a type of brain bleed). The safety data advises against high-dose supplements in pregnancy unless your doctor directs otherwise; amounts from food and prenatal vitamins are fine.
There isn't enough data to know either way for breastfeeding — talk with your doctor or pharmacist about whether high-dose supplements are right for you.
Meds to double-check
Moderate interaction found
Before taking this product, check with your pharmacist if you take blood thinners or antiplatelet drugs (Moderate risk of increased bleeding), chemotherapy drugs like cyclophosphamide or doxorubicin (Moderate risk of reduced drug effectiveness), medications processed through CYP3A4 (Moderate risk of reduced drug levels), cyclosporine (Moderate risk of increased levels), selumetinib (Moderate risk of increased bleeding), or niacin (Minor risk of reduced cholesterol benefit).
The bottom line
Scorecard at a glanceFully disclosed formula with some supporting evidence for its stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.
If you have a vitamin E deficiency or AVED, this product can help. If you take blood thinners, chemotherapy, or other narrow-margin drugs, check with your pharmacist first — vitamin E can change how they work.
Don't start high-dose supplements without talking to your doctor.

Vitamin E 268 mg by Solaray Drug Interactions
HelloPharmacist Interaction Report
Solaray Vitamin E 268 mg interacts with a number of medications, and you'll want to check yours before starting.
The most serious concern is with blood thinners (anticoagulants) and antiplatelet drugs — vitamin E can increase your bleeding risk by interfering with how your blood clots. This effect is dose-dependent, meaning higher doses carry more risk.
Read the full breakdown — every affected drug type, severity by severity
Vitamin E also may reduce how well certain chemotherapy drugs work. This includes alkylating agents like cyclophosphamide and antitumor antibiotics like doxorubicin, which rely on generating free radicals to kill cancer cells.
If you're on cancer treatment, talk to your oncologist before adding this supplement. Additionally, vitamin E may speed up how your liver processes CYP3A4 substrates (a large drug class), potentially lowering their levels and effectiveness — use caution here, especially if you take narrow-margin medications.
There's also a concern with cyclosporine (an immunosuppressant): certain forms of vitamin E may increase how much cyclosporine your body absorbs. And if you take niacin for cholesterol, vitamin E might blunt its benefit to your HDL levels.
Altogether, these interactions span 754 individual medications. Use the checker below to look up your exact drugs before you start.

For each ingredient in Vitamin E 268 mg 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.
