HelloPharmacist Scorecard of Cold Pressed Flax Seed Oil 1000 mg by Trader Joe'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

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: organic cold pressed flax seed oil at 1000 mg per softgel capsule. Flaxseed oil is a plant-based oil rich in alpha-linolenic acid, a type of omega-3 fatty acid.

The softgel capsule itself is an inactive ingredient that holds the oil.

Does it work?

Couldn't assess
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 assessable

This is a single-ingredient Flaxseed Oil product and its label doesn't state a use — see Flaxseed Oil's own graded uses on its monograph.

Why this rating?
  • We looked at the product name, claims, and label statements and couldn't find a stated purpose to grade.

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

That means existing studies haven't shown it works well for these conditions, but more research may change that picture.

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. A small number of people report mild side effects—changes in bowel habits, dry mouth, or upset stomach—usually at higher doses around 5 grams daily.

Severe allergic reactions are rare. Very high doses (30 grams or more daily) have been linked to loose stools and diarrhea.

There isn't enough reliable safety data to make a clear call on whether it's safe during pregnancy, so check with your doctor first. Limited information exists for breastfeeding as well—talk with your doctor or pharmacist before using it while nursing.

Quality and dose vary between brands, so that matters too.

Side effects, ingredient by ingredient 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?
  • 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.

Check with your pharmacist if you take blood thinners or antiplatelet drugs (like warfarin or clopidogrel)—moderate interaction risk. Also flag blood pressure medications, and ezetimibe (Zetia).

The bottom line

Scorecard at a glanceFully disclosed formula with no assessable stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

Flaxseed oil is generally easy to tolerate, but if you take blood thinners, blood pressure medications, or ezetimibe, you need to check with your pharmacist first. The evidence doesn't support it for the common uses people reach for it—obesity, arthritis, mood, and cholesterol.

Talk to us before you start, especially if you're on any medications.

organic cold pressed Flax Seed 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.
