HelloPharmacist Scorecard of Lignan Flax Oil by Barlean's

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

Generated from HelloPharmacist’s pharmacist-curated databases and editorial rules · Last generated Jul 11, 2026

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 5 of its 6 active ingredients.

Barlean's Lignan Flax Oil is a 6-ingredient softgel with flaxseed oil and oleic acid as the active components, alongside linoleic acid, alpha-linolenic acid, polyunsaturated fat, and monounsaturated fat. The product also contains inactive ingredients — gelatin, glycerin, water, caramel color, and flaxseed particulate — that serve as the capsule and filler material.

Flaxseed oil is the star here, a concentrated source of omega-3 fatty acids. Oleic acid is a monounsaturated fat found naturally in foods like olive oil, and it's included for its potential effects on heart health and cholesterol.

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: omega-3 fatty acids and antioxidant lignans support.
  • We looked for evidence on: Atherosclerosis, Cardiovascular disease (CVD), Coronary heart disease (CHD), Hypercholesterolemia, Hyperlipidemia, Hypertension — and 4 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: Flaxseed Oil is rated "Possibly Ineffective" for Hyperlipidemia.

For oleic acid, there is possibly effective evidence it may help lower cholesterol levels (hypercholesterolemia) and support coronary heart disease. However, flaxseed oil has shown possibly ineffective evidence for obesity, rheumatoid arthritis, bipolar disorder, and high cholesterol (hyperlipidemia) — meaning the research doesn't support using it for these purposes.

The data we hold doesn't establish effectiveness for other conditions this product might be marketed for.

The evidence, ingredient by ingredient Oleic Acid 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 2 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 2 of 2.
  • General safety write-ups exist for 2 of 2.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Flaxseed oil is generally well tolerated by most adults. When taken at around 5 grams daily, a small number of patients report changes in bowel habits, dry mouth, or indigestion.

High doses (30 grams or more per day) may cause loose stools or diarrhea. Rare serious reactions like severe allergic reactions (anaphylaxis) have been reported.

Oleic acid in normal food amounts is considered safe, but concentrated supplement doses haven't been well studied. For pregnancy and breastfeeding, the safety data is limited.

Food amounts of oleic acid are fine, but supplement-level doses lack good safety research. Flaxseed oil has insufficient data during breastfeeding — check with your doctor or pharmacist before use if you're pregnant or nursing.

Side effects, ingredient by ingredient Oleic Acid Flaxseed Oil

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?
  • 2 of the 2 matched ingredients can interact with medications — Flaxseed Oil, Oleic Acid.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; diabetes medications.
  • For scale: 379 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 Barlean's Lignan Flax Oil, check with us if you take blood thinners or antiplatelet drugs (Moderate interaction with flaxseed oil), blood pressure medications (Moderate interaction with flaxseed oil), diabetes medications (Moderate interaction with oleic acid), or ezetimibe/Zetia (Moderate interaction with flaxseed oil). No interactions are documented in our data for the other ingredients we could check.

The bottom line

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

This product may appeal to you if you're interested in omega-3 fatty acids and heart health support, but the evidence for flaxseed oil's effectiveness is limited. If you take blood thinners, blood pressure medications, diabetes drugs, or ezetimibe (Zetia), talk to your pharmacist before starting — the interactions are worth a closer look.

Same goes if you're pregnant or breastfeeding.

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.

Likelihood Probable Evidence B
Flaxseed Oil full monograph & interactions

Oleic Acid1 drug type · 86 drugs

Antidiabetes Drugs

Theoretically, oleic acid might increase the effects of antidiabetes drugs. Preliminary clinical research in patients with type 2 diabetes taking oral hypoglycemic drugs shows that eating a diet rich in oleic acid from olive oil decreases fasting blood glucose levels when compared to eating a diet rich in linoleic acid from sunflower oil. It is unknown if taking oleic acid supplements would have this effect or if this change is clinically significant. Until more is known, use caution. Dose adjustment may be necessary. Some antidiabetes drugs include glimepiride (Amaryl), glyburide (DiaBeta, Glynase PresTab, Micronase), insulin, metformin (Glucophage), pioglitazone (Actos), rosiglitazone (Avandia), and others.

Lignan Flax Oil by Barlean's: Common Questions

Does Lignan Flax Oil by Barlean's interact with any medications?
Yes. Based on its ingredients, Lignan Flax Oil has a known interaction with 379 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Lignan Flax Oil 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.
Will this help my cholesterol?
Oleic acid in this product has possibly effective evidence for lowering cholesterol. However, flaxseed oil itself shows possibly ineffective evidence for high cholesterol. The overall benefit depends on your diet and other factors — talk to your doctor about whether this fits your cholesterol plan.
Can I take this while pregnant or breastfeeding?
There isn't enough safety data on concentrated flaxseed oil and oleic acid supplements during pregnancy and breastfeeding. Food amounts are fine, but supplement doses haven't been well studied. Talk with your doctor or pharmacist before taking this if you're pregnant or nursing — they can give you personalized advice.
What are the main side effects?
Most people tolerate it well. At typical doses, a small number report changes in bowel habits, dry mouth, or indigestion. High doses (30 grams or more daily) may cause loose stools or diarrhea. Severe allergic reactions are rare.
Is this the same as eating flaxseed or olive oil?
This is a concentrated supplement, so the dose is much higher than you'd normally get from food. That's why the safety data differs — food amounts are well studied and considered safe, but concentrated supplement doses haven't been researched as thoroughly.
What is the flaxseed particulate in the capsule?
That's an inactive ingredient — a filler that's part of the capsule itself. It doesn't contribute to the supplement's active effects.
Will this help with rheumatoid arthritis or bipolar disorder?
The evidence we hold shows possibly ineffective for both conditions. This supplement is not supported for treating these — if you have either condition, work with your doctor on a treatment plan rather than relying on this product.
