HelloPharmacist Scorecard of Flaxseed Oil 1 gram by Swanson
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
Low disclosure
This softgel contains 1 gram of flaxseed oil, which delivers three omega fatty acids: omega-3 (as DHA, a fish oil component), omega-6, and omega-9. The three active ingredients work together as a source of essential fatty acids.
Gelatin, glycerin, and purified water are the inactive ingredients — the capsule and its fill.
Does it work?
Moderate evidence
The omega-3 (DHA) in this product is possibly effective for high cholesterol (hyperlipidemia) and preterm labor prevention. For cognitive function and ADHD, the evidence rates as possibly ineffective — meaning the studies we hold don't show a clear benefit.
We have no effectiveness data on file for omega-9 or omega-6 on their own.
How safe is it?
Well-documented data
DHA is generally well tolerated at typical supplement doses. The most common side effects are belching, fishy aftertaste, loose stools, and nausea — usually mild.
Rare serious concerns include increased bleeding risk at high doses and isolated reports of rash, acne, or hair loss, though causation isn't clear. In pregnancy, DHA is rated likely safe, often recommended in prenatal care — but use only under your doctor's guidance and choose a purified, low-mercury source.
DHA passes into breast milk and is generally considered acceptable, but check with your doctor on the dose and source for your situation. We have no safety data on file for omega-9 and omega-6.
Meds to double-check
Moderate interaction found
Check with your pharmacist if you take blood thinners or antiplatelet drugs (like warfarin or aspirin), blood pressure medications (antihypertensives), or diabetes medications (like metformin or insulin). DHA in this product may increase bleeding risk with the first group, lower blood pressure dangerously with the second, and reduce the effectiveness of the third.
The bottom line
Scorecard at a glanceFormula with limited ingredient disclosure with some supporting evidence for its stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.
This is a solid choice if you're looking for omega-3 support and don't take blood thinners, blood pressure, or diabetes medications. If you do take any of those, talk to your pharmacist first — the interactions are real and worth planning around.
Your doctor or pharmacist can help you time it right or pick an alternative.

Flaxseed Oil 1 gram by Swanson Drug Interactions
HelloPharmacist Interaction Report
Swanson Flaxseed Oil 1 gram contains omega-3 (from fish oil/DHA), omega-9, and omega-6.
The omega-3 ingredient carries documented interactions with three major medication types. The most serious concern is with blood thinners (anticoagulants) and antiplatelet drugs — DHA may theoretically increase bleeding risk when combined with these medications, though most evidence suggests DHA alone does not significantly affect clotting.
Use with caution if you're on a blood thinner or aspirin-type medication.
Read the full breakdown — every affected drug type, severity by severity
The other two moderate-severity interactions are with blood pressure medications (antihypertensives) — DHA can lower blood pressure and might add to the effect of your medication, risking low blood pressure — and diabetes medications (antidiabetes drugs), where DHA may reduce their effectiveness and increase fasting blood sugar levels. We could not check omega-9 and omega-6 for interactions; interaction data for those is not on file.
Altogether, these interactions span 372 individual medications. Run your exact medications through the checker on this page before you start.

For each ingredient in Flaxseed Oil 1 gram with known interactions, here are the types of medications it can affect. Open any type for the detail — or search your exact drug in the checker above.
Flaxseed Oil
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.
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.
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.
