HelloPharmacist Scorecard of Flaxseed Oil 1000 mg by Thompson
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
This product contains 4 ingredients, three of which are fatty acids: linoleic acid, oleic acid, and alpha-linolenic acid (a plant-based omega-3). The fourth is organic flaxseed oil, the primary active component.
These work together as a source of beneficial fats. The softgel also contains gelatin, natural flavor, and ascorbic acid (vitamin C) as inactive ingredients — these are excipients that help make and preserve the capsule.
Does it work?
Moderate evidence
The oleic acid in this product is possibly effective for high cholesterol and heart disease based on the data we hold, though the evidence is not yet conclusive. Flaxseed oil itself, however, shows mostly negative or insufficient evidence — it's rated possibly ineffective for obesity, arthritis, bipolar disorder, and high cholesterol.
The research doesn't support its use for those conditions at this time.
How safe is it?
Well-documented data
Orally, flaxseed oil is generally well tolerated for most adults. A small number of users — about 3% — have reported changes in bowel habits, dry mouth, or indigestion at typical doses.
Rare but serious allergic reactions like anaphylaxis are possible. At very high doses (30 grams daily or more), loose stools and diarrhea have been reported.
Oleic acid at food amounts is recognized as safe, but concentrated supplements in pregnancy and breastfeeding lack good safety data. Flaxseed oil itself is rated possibly safe in pregnancy, but limited safety information exists for breastfeeding — talk with your doctor or pharmacist before use if you're pregnant or nursing.
Meds to double-check
Moderate interaction found
Before taking this product, double-check with your doctor or pharmacist if you're on blood thinners or antiplatelet drugs (Moderate risk of increased bleeding), blood pressure medications (Moderate risk of added blood-pressure-lowering), diabetes drugs (Moderate risk of added blood-sugar-lowering), or ezetimibe/Zetia (Moderate risk of reduced flaxseed absorption). Altogether, these interactions span 379 individual medications.
The bottom line
Scorecard at a glanceFully disclosed formula with some supporting evidence behind its ingredients' uses. Moderate medication interactions have been identified, and safety information is well characterized.
This product may be worth considering if you're interested in omega-3 and monounsaturated fats, though evidence for specific health claims is weak. If you take blood thinners, blood pressure drugs, diabetes medication, or ezetimibe (Zetia), you'll need to check with your doctor or pharmacist before starting — interactions are documented and could affect how your medications work.
Speak with your own healthcare provider about whether it fits your situation.

Flaxseed Oil 1000 mg by Thompson Drug Interactions
HelloPharmacist Interaction Report
Thompson's Flaxseed Oil 1000 mg can interact with blood pressure drugs and blood thinners through its flaxseed oil content, and with diabetes medications through oleic acid.
The most serious concern is a Moderate interaction with blood thinners (anticoagulants and antiplatelet drugs) — flaxseed oil may increase bleeding risk by thinning the blood further, though the effect is modest based on available studies.
Read the full breakdown — every affected drug type, severity by severity
Flaxseed oil also has a Moderate interaction with blood pressure medications (antihypertensive drugs); taking it alongside these drugs could add up and lower your pressure more than intended. Similarly, oleic acid in this product may increase the effects of diabetes drugs (oral hypoglycemic agents), potentially lowering blood sugar more than expected.
One more thing to watch: the cholesterol medication ezetimibe (Zetia) blocks how your body absorbs alpha-linolenic acid from flaxseed, reducing the supplement's intended effect.
We were not able to check linoleic acid and alpha-linolenic acid as standalone ingredients — we hold no data for those. Before you start this product, run your exact medications through the checker on this page.

For each ingredient in Flaxseed Oil 1000 mg with known interactions, here are the types of medications they can affect. Open any type for the detail — or search your exact drug in the checker above.
organic Flax seed 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.
Oleic Acid
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.
