HelloPharmacist Scorecard of Tri Omega DHA by KeyView Labs

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
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 8 of its 8 active ingredients.
  • “OmegaChoice Omega-3 Essential Fatty Acids:” is listed as a grouped ingredient — the label doesn't break down how much of each component you get.
  • “TocoSource Tocotrienol Complex” is a proprietary blend — the label gives one combined amount (70 mg) without saying how much of each component you get.

Tri Omega DHA contains 8 active ingredients: omega-3 fatty acids (eicosapentaenoic acid and docosahexaenoic acid), vitamin E compounds (D-alpha-tocopherol and four tocotrienols: D-gamma, D-alpha, D-delta, and D-beta), and essential fatty acids. The omega-3s and vitamin E work together as antioxidants and may support heart and brain health.

The product is delivered in a softgel capsule with fish oil concentrate, gelatin, and the capsule shell as inactive ingredients.

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: improve brain function and heart health.
  • We looked for evidence on: Age-related cognitive decline, Alzheimer disease, Cardiovascular disease (CVD), Coronary artery bypass graft (CABG) surgery, Dementia, Hypercholesterolemia — and 4 related terms.
  • The strongest evidence on file: Vitamin E is rated "Possibly Effective" for Alzheimer disease (Natural Medicines).
  • Also on file: Vitamin E is rated "Possibly Ineffective" for Age-related macular degeneration (AMD), Angina, Atherosclerosis, Congestive heart failure (CHF).
  • Also on file: Vitamin E is rated "Likely Ineffective" for Cardiovascular disease (CVD).

The effectiveness data we hold covers only the vitamin E portion of this product. Vitamin E is effective for treating vitamin E deficiency and a rare genetic condition called ataxia with vitamin E deficiency (AVED).

It's possibly effective for Alzheimer disease, beta-thalassemia, glucose-6-phosphate dehydrogenase (G6PD) deficiency, and intracranial hemorrhage. We don't have effectiveness ratings in our data for the omega-3 fatty acids or essential fatty acids in this formula, so we can't comment on whether those ingredients work for their intended purposes.

The evidence, ingredient by ingredient Tocotrienols 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 safe, but the safety data cautions against high-dose long-term supplements — they may raise the risk of bleeding and other harms. Vitamin E is generally well tolerated orally, though serious side effects are rare and include bleeding, hemorrhagic stroke, and cardiovascular complications.

There's particular concern about increased risk of hemorrhagic stroke in male smokers taking synthetic vitamin E for several years, though other studies have shown mixed results. High doses raise bleeding risk, especially in people with vitamin K deficiency or those taking blood thinners or antiplatelet drugs.

During pregnancy, amounts from food and prenatal vitamins are appropriate, but avoid high-dose supplements unless your doctor directs otherwise. During lactation, normal dietary amounts are fine, but check with your doctor before taking high-dose supplements.

Meds to double-check

Moderate interaction found
Known Interaction Concern · database check
Moderate identified

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 taking Tri Omega DHA, check with your doctor or pharmacist if you take blood thinners or antiplatelet drugs (like aspirin or clopidogrel), warfarin, chemotherapy drugs (especially alkylating agents or antitumor antibiotics), selumetinib, cyclosporine, medications broken down by the liver's CYP3A4 pathway, or niacin. These interactions are all moderate or minor severity, but the vitamin E dose in this product matters for safety.

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.

Tri Omega DHA is worth considering if you want omega-3s and vitamin E, but be especially cautious if you take blood thinners, antiplatelet drugs, warfarin, chemotherapy, niacin, or cyclosporine. The vitamin E interactions are moderate and dose-dependent, so the dose in this product matters.

Talk with your doctor or pharmacist before starting — they can check your specific medications and confirm this is right for you.

Anticoagulant/Antiplatelet Drugs

Concomitant use of tocotrienols with anticoagulant or antiplatelet agents might increase the risk of bleeding. However, this has not been reported in humans.
Taking tocotrienols orally inhibits experimentally-induced platelet aggregation in humans. 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.

Tri Omega DHA by KeyView Labs: Common Questions

Does Tri Omega DHA by KeyView Labs interact with any medications?
Yes. Based on its ingredients, Tri Omega DHA 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?
Tri Omega DHA 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?
Not without checking first with your doctor. The vitamin E in this product can increase your bleeding risk if combined with warfarin, especially at higher doses. Your doctor needs to know you're considering it so they can monitor your INR and bleeding signs.
What do the omega-3s in this supplement do?
Eicosapentaenoic acid and docosahexaenoic acid are omega-3 fatty acids. We don't have effectiveness data on file for them in this product, so I can't tell you what the evidence shows for what they're meant to do. Your doctor or pharmacist can discuss their potential roles.
Is vitamin E safe to take long-term?
Usual dietary amounts are safe, but high-dose supplements taken long-term may raise your risk of bleeding and other problems. This product contains multiple vitamin E forms, so ask your doctor or pharmacist whether the dose here is appropriate for you to take regularly.
Is this safe during pregnancy?
Amounts from food and prenatal vitamins are fine, but avoid high-dose vitamin E supplements during pregnancy unless your doctor directs otherwise. Talk with your doctor before starting this product to make sure the dose is safe for you.
Can I take this while breastfeeding?
Normal dietary amounts of vitamin E are likely safe while breastfeeding, but check with your doctor before taking high-dose supplements. Since this product has multiple vitamin E compounds, your doctor should review the total dose for you.
What side effects might I notice?
Vitamin E is generally well tolerated, and most people don't have problems. Serious side effects like bleeding or stroke are rare. High doses raise your bleeding risk, especially if you take blood thinners or have a vitamin K deficiency — this is why it's important to check with your doctor first.
