HelloPharmacist Scorecard of Cotrienol DG by Bronson

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 1 of its 1 active ingredient.
  • No proprietary blends here — you can verify the dose of every single component.

Cotrienol DG contains one active ingredient: DeltaGold tocotrienol, a form of vitamin E. The product also includes inactive ingredients (soy lecithin, rice bran oil, gelatin, purified water, and glycerin) that help deliver and stabilize the capsule.

Does it work?

Not established
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
Not established

The graded evidence we hold for these ingredients covers different conditions than the ones this product is marketed for, so there's no established rating for its stated use — see Tocotrienols's own graded uses on its monograph.

Why this rating?
  • The label markets this product for: promotes overall heart health and maintains healthy cholesterol levels.
  • We looked for evidence on: Hypercholesterolemia, Metabolic syndrome, Cardiovascular disease, Dyslipidemia.
  • The closest evidence on file: Tocotrienols is rated "Possibly Ineffective" for Hypercholesterolemia (Natural Medicines).
  • Also on file: Tocotrienols is rated "Insufficient Reliable Evidence To Rate" for Metabolic syndrome.

The evidence for tocotrienols is mixed. For diabetes, the data rates it as possibly effective — meaning there's some promising research, but it's not conclusive.

For high cholesterol, the evidence rates it as possibly ineffective. For alopecia areata (patchy hair loss) and breast cancer, there isn't enough reliable evidence to say whether it works.

The evidence, ingredient by ingredient Tocotrienols

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.

Tocotrienols are generally well tolerated when taken by mouth, and no adverse effects have been reported in clinical trials. However, long-term safety at supplement doses isn't firmly established.

During pregnancy, there isn't enough safety information, so it's best to avoid it. While breastfeeding, little is known about safety — talk with your doctor or pharmacist before using it.

Side effects, ingredient by ingredient Tocotrienols

Meds to double-check

Minor interactions only
Known Interaction Concern · database check
Minor only

Only Minor-severity interactions are documented for these ingredients.

Why this rating?
  • 1 of the 1 matched ingredient can interact with medications — Tocotrienols.
  • The most serious interaction on file is rated Minor.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs.
  • For scale: 122 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.

Check any anticoagulant or antiplatelet drugs you take — blood thinners like warfarin, aspirin, clopidogrel, and similar medications. The interaction is rated Minor and hasn't been reported in people, but because tocotrienols can inhibit platelet clumping in lab studies, it's worth confirming your specific medications.

The bottom line

Scorecard at a glanceFully disclosed formula with no established evidence rating for its marketed use. Only minor medication interactions are documented, and safety information is well characterized.

Cotrienol DG may be worth considering if you're interested in its possible effect on diabetes or are simply exploring vitamin E supplementation. If you take blood thinners or antiplatelet medications, check your exact drugs with our tool first.

Pregnant people should avoid it; anyone breastfeeding should ask their doctor. Chat with your pharmacist about whether this fits your situation.

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.

Yes. Based on its ingredients, Cotrienol DG has a known interaction with 122 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Cotrienol DG contains a single active ingredient, and that one ingredient can interact with many different medications on its own. We check it against each medication and show the mechanism 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.
Does tocotrienol work for high cholesterol?
The evidence rates it as possibly ineffective for lowering cholesterol, so it's not a reliable choice for that goal.
Can I take this if I'm pregnant?
No — there isn't enough safety information during pregnancy, so it's best to avoid supplemental doses. Talk with your doctor if you have questions.
What about while breastfeeding?

Are there any side effects?
When taken by mouth, tocotrienols appear well tolerated, and no adverse effects have been reported in clinical trials.
Is this really just one ingredient?
Yes — the active ingredient is tocotrienol (DeltaGold). The softgel also contains inactive ingredients like soy lecithin, rice bran oil, and gelatin to make the capsule work, but those aren't the active part.
