HelloPharmacist Scorecard of Omega-3 1,000 mg Plus Vitamin E by NatureWise

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.

From our pharmacy team — supplement deep dive

What’s inside

Full disclosure
Ingredient Transparency · database check
Full

Every active ingredient lists its own amount on the label.

Why this rating?
  • The label discloses an exact amount for 4 of its 4 active ingredients.
  • “Total Omega-3 Fatty Acids” is listed as a grouped ingredient — the label gives one combined amount (1,060 mg) without saying how much of each component you get.

This softgel contains 4 active ingredients. Vitamin E is the one we have detailed information on; it's an antioxidant that your body needs and one your system can't make on its own.

The other three are omega-3 fatty acids: total omega-3s, other fatty acids, and eicosapentaenoic acid. The product also contains inactive ingredients — gelatin, glycerin, purified water, and natural lemon flavor — that help form and flavor the capsule.

Does it work?

Moderate evidence
Evidence for Intended Use · database check
By FDA rules, dietary supplements can’t claim to treat, cure, or prevent disease — so labels speak in careful marketing language. We discern each product’s intended use from its name, label claims, and label statements, then grade the clinical evidence for that use. How these ratings are computed
Moderate

Some clinical evidence supports this product's ingredients for its stated purpose, but it isn't conclusive.

Why this rating?
  • The label markets this product for: Heart, immune, and bone support.
  • We looked for evidence on: Cardiovascular disease (CVD), Angina, Atherosclerosis, Congestive heart failure (CHF), Coronary artery bypass graft (CABG) surgery, Nitrate tolerance — and 4 related terms.
  • The strongest evidence on file: Vitamin E is rated "Possibly Effective" for Nitrate tolerance (Natural Medicines).
  • Also on file: Vitamin E is rated "Possibly Ineffective" for Angina, Atherosclerosis, Congestive heart failure (CHF).
  • Also on file: Vitamin E is rated "Likely Ineffective" for Cardiovascular disease (CVD).

We have effectiveness data for vitamin E only. It's rated effective for vitamin E deficiency itself and for a rare genetic condition called AVED (ataxia with vitamin E deficiency).

It's possibly effective for Alzheimer disease, beta-thalassemia, G6PD deficiency, and intracranial hemorrhage. For the omega-3 ingredients in this product, we don't hold effectiveness ratings in our data.

The evidence, ingredient by ingredient Vitamin E

How safe is it?

Well-documented data
Safety Information · database check
Well characterized

Adverse-effect, pregnancy, and general safety data are on file for most of these ingredients.

Why this rating?
  • We hold adverse-effect (side-effect) data for 1 of the 1 matched ingredient.
  • Pregnancy & breastfeeding safety ratings cover 1 of 1.
  • General safety write-ups exist for 1 of 1.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Vitamin E from food and normal dietary amounts is generally well-tolerated. However, the safety notes flag a concern with high-dose long-term supplements — they may raise your risk of bleeding and other harms.

In rare cases, high-dose vitamin E has been linked to serious bleeding, hemorrhagic stroke, and cardiovascular problems. The risk of bleeding appears to increase with dose, especially in people who are already taking blood thinners or have vitamin K deficiencies.

During pregnancy, amounts from food and prenatal vitamins are fine, but high-dose supplements should only be taken if your doctor directs it. While breastfeeding, normal dietary amounts are okay, but check with your doctor before taking high-dose supplements.

We don't have pregnancy or breastfeeding safety data on file for the omega-3 ingredients.

The most serious documented interaction for these ingredients is Moderate. Check your medications for a personalized result.

Why this rating?
  • 1 of the 1 matched ingredient can interact with medications — Vitamin E.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; immunosuppressants / transplant drugs; cancer treatments.
  • For scale: 765 individual medications appear in the full list. A big number alone doesn't make a product dangerous — what matters is whether YOUR medication is on it, so run yours through the interaction checker on this page.

Before you take this, check with your pharmacist or doctor if you're on blood thinners like warfarin, antiplatelet drugs (like aspirin or clopidogrel), chemotherapy drugs (especially alkylating agents or antitumor antibiotics), selumetinib, cyclosporine, certain liver-metabolized drugs, or niacin. Altogether, these interactions span 754 individual medications.

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're not on blood thinners or chemotherapy, this product is worth considering for vitamin E supplementation. If you do take anticoagulants, antiplatelet drugs, or certain cancer medications, talk to your pharmacist or doctor first — the vitamin E here could affect how those drugs work or raise your bleeding risk.

Always check your full medication list before starting.

Vitamin E8 drug types · 764 drugs

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.

Likelihood Possible Evidence D
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.

Likelihood Possible Evidence B
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.

Likelihood Possible Evidence D
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.

Likelihood Unlikely Evidence B
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.

Likelihood Possible Evidence D
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.

Likelihood Possible Evidence D
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.

Likelihood Possible Evidence B
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.

Omega-3 1,000 mg Plus Vitamin E by NatureWise: Common Questions

Does Omega-3 1,000 mg Plus Vitamin E by NatureWise interact with any medications?
Yes. Based on its ingredients, Omega-3 1,000 mg Plus Vitamin E has a known interaction with 764 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Omega-3 1,000 mg Plus Vitamin E contains 4 active ingredients, and an interaction can come from any of them. We check every ingredient, combine the results into one list per medication, and show which ingredient and mechanism is responsible.
Where does this information come from?
The product label data comes from the NIH Dietary Supplement Label Database (DSLD); the interaction data is built on the Natural Medicines database and reviewed by HelloPharmacist pharmacists.
Can I take this if I'm on warfarin?
The vitamin E in this product can increase your bleeding risk when combined with warfarin. This is a moderate interaction, so you need to talk to your pharmacist or doctor before starting — they may want to monitor you more closely or adjust your plan.
Is vitamin E safe at this dose?
Vitamin E from food is safe, and this supplement's dose isn't extreme. But the safety data does flag that high-dose long-term vitamin E supplements may raise bleeding risk and, in rare cases, other harms. It's safest to use this product as directed and tell your doctor if you're taking it.
What does vitamin E actually do?
Vitamin E is an antioxidant your body needs but can't make on its own. It's effective for treating actual vitamin E deficiency and a rare genetic condition called AVED, and possibly helpful for Alzheimer disease, beta-thalassemia, and a couple of other conditions.
Can I take this while pregnant?
Vitamin E from food and prenatal vitamins is fine during pregnancy. This supplement counts as a high-dose form, so you should only take it if your doctor says to. We don't have safety data on the omega-3 ingredients, so ask your doctor about the whole product.
Will this help my heart or cholesterol?
We don't have effectiveness data for the omega-3 ingredients in our records, so I can't say. What I can tell you is that if you're taking niacin for cholesterol, the vitamin E here might reduce its benefits — so let your pharmacist know about both.
What about side effects?
Vitamin E is generally well-tolerated at normal doses. Serious side effects are rare but can include bleeding, hemorrhagic stroke, and cardiovascular problems — mainly a concern at high doses, especially if you're already at risk. Take this product as directed and mention it to your doctor or pharmacist.
