HelloPharmacist Scorecard of OmegaTru Hemp Seed Oil by Swanson EFAs

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

Partial disclosure
Ingredient Transparency · database check
Partial

Most active ingredients list an amount, but at least one is hidden in a blend or missing.

Why this rating?
  • The label discloses an exact amount for 4 of its 5 active ingredients.
  • “certified organic Hemp Seed Oil” is listed as a grouped ingredient — the label gives one combined amount (1 Gram(s)) without saying how much of each component you get.

OmegaTru Hemp Seed Oil is a softgel with five active ingredients. The product contains certified organic hemp seed oil as its base, plus oleic acid, linoleic acid, alpha-linolenic acid, polyunsaturated fat, and monounsaturated fat — all fatty acids naturally found in seeds and oils.

The inactive ingredients are gelatin, glycerin, and purified water.

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: essential fatty acids and heart health support.
  • We looked for evidence on: Coronary heart disease (CHD), Familial hypercholesterolemia, Hypercholesterolemia, Hypertension, Stroke, dyslipidemia — and 1 related terms.
  • The strongest evidence on file: Oleic Acid is rated "Possibly Effective" for Coronary heart disease (CHD) (Natural Medicines).
  • Also on file: Oleic Acid is rated "Possibly Effective" for Hypercholesterolemia.
  • Also on file: Oleic Acid is rated "Insufficient Reliable Evidence To Rate" for Hypertension, Stroke.

The evidence we hold applies only to oleic acid, one component in this product. Oleic acid is rated possibly effective for high cholesterol (hypercholesterolemia) and possibly effective for coronary heart disease.

We don't have effectiveness data on file for the other ingredients in this formula — whether hemp seed oil as a whole, or the other individual fatty acids, have established benefits isn't covered in the facts we hold.

How safe is it?

Some data gaps
Safety Information · database check
Some gaps

Safety data exists for these ingredients, but with some important gaps.

Why this rating?
  • We hold adverse-effect (side-effect) data for 0 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.

Oleic acid from food sources like olive oil is generally recognized as safe at normal eating amounts. However, concentrated supplement doses of oleic acid are not well studied in pregnancy or while breastfeeding — the safety data we hold advises caution with supplement-level amounts during these times.

Talk with your doctor or pharmacist about whether this product is right for you if you're pregnant, breastfeeding, or planning to become pregnant. We don't have safety data on file for the other fatty acid ingredients in this formula.

Side effects, ingredient by ingredient Hemp Oleic Acid

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 — Oleic Acid.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: diabetes medications.
  • For scale: 86 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.

If you take antidiabetes drugs (blood sugar-lowering medications), flag this product with your doctor or pharmacist before you use it — oleic acid in this formula may boost how well those medications work. We couldn't check the interaction data for the other fatty acid ingredients, so run your exact medication list through the search tool on this page.

The bottom line

Scorecard at a glancePartially disclosed formula with some supporting evidence for its stated purpose. Moderate medication interactions have been identified, and some safety-information gaps remain.

This product is a fatty acid blend centered on hemp seed oil, with oleic acid as a tracked component. If you take blood sugar-lowering medication, you'll want to confirm with your doctor or pharmacist before starting, since oleic acid may strengthen those drugs' effects.

Pregnant or breastfeeding people should also talk it over with their own healthcare provider first, as concentrated supplement doses haven't been well studied in those situations.

Estrogens

Theoretically, hemp might interfere with hormone therapy due to its estrogenic effects.
In an ovariectomized animal model, a diet containing hemp seed 1%, 2%, or 10% resulted in normalized plasma levels of 17-beta-estradiol. The mechanism of action for this effect is unclear.

Likelihood Possible Evidence D
Ace Inhibitors (Aceis)

Theoretically, consuming hemp seed protein isolate with ACE inhibitors might have additive effects and increase the risk of hypotension.
Hemp seed protein hydrolysate has shown ACE inhibitor-like effects in a hypertensive animal model. However, hempseed oil consumption does not seem to reduce blood pressure in humans. Until more is known, monitor blood pressure and potassium levels.

Likelihood Unlikely Evidence D
Anticoagulant/Antiplatelet Drugs

Theoretically, hemp seed might increase the risk of bleeding when used concomitantly with anticoagulant/antiplatelet drugs.
In animal research, hemp seed at 5% of the diet inhibits platelet aggregation in vitro. However, in human research, taking hemp seed oil 2 grams daily for 12 weeks does not inhibit the aggregation of platelets in vitro.

Likelihood Possible Evidence D
Antihypertensive Drugs

Theoretically, hemp seed protein may have additive effects with antihypertensive drugs.
In a hypertensive animal model, hemp seed protein hydrolysate reduced systolic blood pressure by a mechanism possibly involving the inhibition of renin and angiotensin converting enzyme (ACE) activities. However, there was no effect of hemp seed protein on blood pressure in normotensive animals. Furthermore, hempseed oil consumption does not seem to reduce blood pressure in humans.

Likelihood Unlikely Evidence D
Cytochrome P450 1A2 (Cyp1A2) Substrates

Theoretically, hemp might decrease the levels and clinical effects of CYP1A2 substrates.
In vitro research shows that hemp induces CYP1A2 enzymes.

Likelihood Possible Evidence D
Cytochrome P450 3A4 (Cyp3A4) Substrates

Theoretically, hemp might decrease the levels and clinical effects of CYP3A4 substrates.
In vitro research shows that hemp induces CYP3A4 enzymes.

OmegaTru Hemp Seed Oil by Swanson EFAs: Common Questions

Does OmegaTru Hemp Seed Oil by Swanson EFAs interact with any medications?
Yes. Based on its ingredients, OmegaTru Hemp Seed Oil has a known interaction with 1,018 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
OmegaTru Hemp Seed Oil 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.
Is this safe to take while pregnant or breastfeeding?
The safety data on file doesn't give us a clear answer for either pregnancy or breastfeeding — concentrated doses of oleic acid haven't been well studied in those situations, though food amounts are considered fine. Talk with your doctor or pharmacist for personalized advice based on your circumstances.
What is oleic acid, and why is it in this product?
Oleic acid is a fatty acid naturally found in seeds and oils, including hemp seed oil. It's possibly effective for high cholesterol and heart disease, which is likely why it's included in this formula.
Does this product work for high cholesterol?
Oleic acid, one of the active ingredients here, is rated possibly effective for high cholesterol. The product also contains other fatty acids and hemp seed oil, but we don't have effectiveness data on those in our system.
Will this interfere with my blood sugar medication?
Yes — oleic acid in this product may increase the effects of antidiabetes drugs (blood sugar-lowering medications), which means your blood sugar might drop more than usual. Check with your doctor or pharmacist before starting to see if a dose adjustment or closer monitoring is needed.
What are the inactive ingredients?
The capsule is made of gelatin, glycerin, and purified water — these are fillers and binding agents to hold the softgel together, not active ingredients.
Why couldn't you check some of the ingredients for interactions?
We don't hold complete interaction data for polyunsaturated fat, monounsaturated fat, linoleic acid, or alpha-linolenic acid. That doesn't mean they're risk-free — it just means we don't have the monographs on file to check them. Your pharmacist can help you assess any concerns.
