HelloPharmacist Scorecard of Flaxseed Oil 1000 mg by Jarrow Formulas

Four independent checks of what is known — a summary of the available information, not a grade of the product itself.

Evidence for Intended Use
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

None of the active ingredients could be matched to our evidence database, so intended use can't be graded.

Why this rating?
  • None of the active ingredients could be matched to a HelloPharmacist monograph, so intended use can't be graded against our evidence data.
Ingredient Transparency
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.
  • “organic Flaxseed Oil” is listed as a grouped ingredient — the label gives one combined amount (1,000 mg) without saying how much of each component you get.
Known Interaction Concern
Not assessable

None of the active ingredients could be matched to our interaction database.

Why this rating?
  • We couldn't match any ingredient to a HelloPharmacist monograph, so there was nothing to check interactions against.
Safety Information
Unable to assess

None of the active ingredients could be matched to our safety data.

Why this rating?
  • We couldn't match any ingredient to a HelloPharmacist monograph, so there was no safety data to measure.

HelloPharmacist summaryFully disclosed formula with no assessable stated purpose. Medication interactions could not be assessed, and safety information could not be assessed.

Assessment coverage: 0 of 1 active ingredient matched to our full ingredient reviews (monographs). Based on the product label dated Feb 25, 2021.

This Scorecard evaluates available label information, ingredient evidence, and known medication-safety considerations. It does not independently verify product identity, purity, potency, contamination, or manufacturing quality. How these ratings are computed

Formula

Jarrow Formulas Flaxseed Oil softgels provide the finest source of organic cold-pressed flaxseed oil. These softgels provide a rich source of the omega-3 fatty acid, alpha linolenic acid (18:3n-3). The flaxseed oil is extracted from organically-grown flaxseeds by an expeller-press, cold-extraction method that safeguards the special long chain fatty acids from excessive heat. Throughout the entire process, care is taken to avoid contact with air (via nitrogen flushing), light, and high temperatures. Jarrow Formulas Flaxseed Oil is made with organic, unrefined flaxseed oil and contains all the natural constituents found in fresh flaxseed oil.

organic 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.
