HelloPharmacist Scorecard of Vegan Flaxseed Oil by DEVA

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.

This product contains one active ingredient: flaxseed oil. Flaxseed oil is derived from flaxseeds and is a source of alpha-linolenic acid, an omega-3 fatty acid.

The capsules also contain inactive ingredients — cellulose, organic orange oil, silica, and mixed tocopherols — which serve as the capsule material and stabilizers.

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 Flaxseed Oil's own graded uses on its monograph.

Why this rating?
  • The label markets this product for: Omega-3 fatty acid source.
  • We looked for evidence on: Atherosclerosis, Cardiovascular disease (CVD), Hyperlipidemia, Hypertension, Dry skin, Rheumatoid arthritis (RA) — and 4 related terms.
  • The closest evidence on file: Flaxseed Oil is rated "Possibly Ineffective" for Hyperlipidemia (Natural Medicines).
  • Also on file: Flaxseed Oil is rated "Possibly Ineffective" for Rheumatoid arthritis (RA).
  • Also on file: Flaxseed Oil is rated "Insufficient Reliable Evidence To Rate" for Atherosclerosis, Cardiovascular disease (CVD), Dry skin, Hypertension, and more.

The evidence for flaxseed oil's effectiveness is limited. According to the data we hold, flaxseed oil is rated possibly ineffective for obesity, rheumatoid arthritis, bipolar disorder, and high cholesterol (hyperlipidemia).

This means the current clinical evidence does not support its use for these conditions, though research is ongoing.

The evidence, ingredient by ingredient Flaxseed Oil

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.

Flaxseed oil is generally well tolerated when taken by mouth. The most common side effects are mild and uncommon — only about 3% of people in studies reported changes in bowel habits, dry mouth, or indigestion at typical doses of around 5 grams daily.

At much higher doses (30 grams per day or more), loose stools and diarrhea have been reported. Severe allergic reactions like anaphylaxis are rare.

The product facts note that safety data is limited, so it's wise to check with your doctor before starting. There isn't enough safety information on file for use during breastfeeding — talk with your doctor or pharmacist before taking it if you're nursing.

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 — Flaxseed Oil.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs.
  • For scale: 293 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 DEVA Vegan Flaxseed Oil, check your medications with your pharmacist, especially blood thinners and antiplatelet drugs (which carry Moderate risk of increased bleeding), blood pressure medications (Moderate risk of low blood pressure), and ezetimibe/Zetia (Moderate risk of reduced drug absorption).

The bottom line

Scorecard at a glanceFully disclosed formula with no established evidence rating for its marketed use. Moderate medication interactions have been identified, and safety information is well characterized.

This product may be worth considering if you're curious about flaxseed oil's potential health effects, but the evidence for its effectiveness against the conditions it's marketed for is weak. If you take blood thinners, blood pressure medications, or ezetimibe, you need to check with us or your doctor first.

Quality and dose vary, so chat with your pharmacist before you start.

Flaxseed Oil3 drug types · 293 drugs

Anticoagulant/Antiplatelet Drugs

Theoretically, using flaxseed oil in combination with anticoagulant or antiplatelet drugs might have additive effects and increase the risk of bleeding.
Small clinical studies show that consuming flaxseed oil might decrease platelet aggregation and increase bleeding time.

Likelihood Possible Evidence D
Antihypertensive Drugs

Theoretically, combining flaxseed oil with other antihypertensive drugs might have additive effects and increase the risk of hypotension.
Some clinical evidence suggests that long-term consumption of flaxseed oil can modestly lower systolic and diastolic blood pressure, while other clinical research shows no effect.

Likelihood Possible Evidence D
Ezetimibe (Zetia)

Concomitant use of flaxseed oil and ezetimibe reduces the absorption of alpha-linolenic acid from flaxseed oil.
In one clinical study, concomitant consumption of ezetimibe 10 mg daily with flaxseed oil 2 grams providing 1 gram of alpha-linolenic acid daily blocked the absorption of alpha-linolenic acid, resulting in an overall reduction in alpha-linolenic plasma levels from baseline.

Vegan Flaxseed Oil by DEVA: Common Questions

Does Vegan Flaxseed Oil by DEVA interact with any medications?
Yes. Based on its ingredients, Vegan Flaxseed Oil has a known interaction with 293 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Vegan Flaxseed 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.
What does flaxseed oil actually do?
Flaxseed oil is a source of alpha-linolenic acid, an omega-3 fatty acid. It's been studied for conditions like high cholesterol, arthritis, and obesity, but the clinical evidence so far suggests it's possibly ineffective for those uses. It may modestly lower blood pressure in some people, though other studies show no effect.
Will this cause side effects?
Most people tolerate it well. Only about 3% of people reported mild side effects like changes in bowel habits, dry mouth, or indigestion at typical doses. At very high doses (30 grams daily or more), loose stools and diarrhea have been reported. Severe allergic reactions are rare but possible.
Is this safe to take if I'm pregnant or breastfeeding?
There isn't enough safety data on file for either pregnancy or breastfeeding. Talk with your doctor or pharmacist before taking it if you're pregnant or nursing — they can give you personalized advice based on your situation.
Why does this product interact with so many medications?
The interaction count (291 medications) reflects the total number of individual drugs affected across all the documented interaction types — blood thinners, blood pressure drugs, and ezetimibe — not that every medication causes a problem. Your specific medications may or may not be on that list. Use the checker to see yours.
Can I take this with my cholesterol medication?
It depends on which one. If you take ezetimibe (Zetia), flaxseed oil can reduce how much ezetimibe your body absorbs, making it less effective. Talk with your pharmacist about your specific medication before starting.
