HelloPharmacist Scorecard of Certified Organic Flax Oil by Flora

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 5 of its 5 active ingredients.
  • No proprietary blends here — you can verify the dose of every single component.

Flora's flax oil is a liquid supplement with 5 active ingredients: polyunsaturated fat, monounsaturated fat, linoleic acid, oleic acid, and alpha-linolenic acid. These are fatty acids and fats naturally present in flax seed.

The product also contains organic flax seed oil as an inactive ingredient.

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

This product doesn't appear to be marketed for a specific use, so we graded Oleic Acid's overall clinical evidence instead.

Moderate

Some clinical evidence supports Oleic Acid for:

Why this rating?
  • We looked at the product name, claims, and label statements and couldn't find a stated purpose to grade.
  • Since the label doesn't commit to one use, we graded the ingredient's overall clinical evidence instead.
  • On file: Coronary heart disease (CHD) — rated "Possibly Effective" (Natural Medicines).
  • On file: Hypercholesterolemia — rated "Possibly Effective" (Natural Medicines).

Oleic acid—one of the active components—is rated possibly effective for lowering cholesterol (hypercholesterolemia) and possibly effective for supporting heart health (coronary heart disease). We don't have effectiveness data in our files for the other active ingredients in this product.

The evidence, ingredient by ingredient Oleic Acid

How safe is it?

Some data gaps
Safety Information · database check
Some gaps

Safety data exists for these ingredients, but with some important gaps.

Why this rating?
  • We hold adverse-effect (side-effect) data for 0 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.

Oleic acid is generally recognized as safe when eaten in normal food amounts, like those in olive oil. However, concentrated supplement doses haven't been well studied in pregnancy or while breastfeeding.

The food amounts you'd get from a normal diet are considered safe, but supplement-level doses lack good safety data. If you're pregnant or nursing, talk with your doctor or pharmacist before starting this product.

Side effects, ingredient by ingredient Oleic Acid

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 — Oleic Acid.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: diabetes medications.
  • For scale: 86 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.

If you take antidiabetes drugs (medications that lower blood sugar), double-check with your doctor or pharmacist before starting this product—oleic acid may increase how well these medications work. We couldn't check the other fatty acid ingredients against medication databases, so mention all your prescriptions when you ask.

The bottom line

Scorecard at a glanceFully disclosed formula with some supporting evidence behind its ingredients' uses. Moderate medication interactions have been identified, and some safety-information gaps remain.

This flax oil may be worth considering if you're interested in heart health and cholesterol support, since oleic acid shows some promise for both. If you take blood sugar medications, you'll want to check with your doctor or pharmacist first—the oleic acid in this product could boost their effect.

Same goes if you're pregnant or breastfeeding; discuss it with your own healthcare provider before you start.

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.

Certified Organic Flax Oil by Flora: Common Questions

Does Certified Organic Flax Oil by Flora interact with any medications?
Yes. Based on its ingredients, Certified Organic Flax Oil has a known interaction with 86 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Certified Organic Flax Oil contains 3 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 flax oil lower my cholesterol?
The oleic acid in flax oil is rated possibly effective for lowering cholesterol and supporting heart health. That means there's some research backing it, but it's not a proven remedy—talk with your doctor about how it might fit into your overall plan.
Can I take this if I'm pregnant or breastfeeding?
We don't have enough safety data for supplement-level doses during pregnancy or while nursing. Food amounts are considered safe, but this concentrated form hasn't been well studied. Check with your doctor or pharmacist for personalized advice before starting.
What exactly is in this flax oil?
It contains five active fatty acids and fats—polyunsaturated fat, monounsaturated fat, linoleic acid, oleic acid, and alpha-linolenic acid—all naturally found in flax seed. The inactive ingredient is organic flax seed oil itself.
Are there any side effects I should know about?
We don't have adverse effects listed in our data for this product. That doesn't mean none exist—it just means we don't hold that information on file.
Is this safe to use with my blood sugar medications?
Oleic acid in this product may boost the effect of antidiabetes drugs (medications that lower blood sugar), which could lower your blood sugar more than intended. Talk with your doctor or pharmacist before adding this to your routine if you take any diabetes medications.
