HelloPharmacist Scorecard of Flaxseed Oil by Herbal Secrets

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

Generated from HelloPharmacist’s pharmacist-curated databases and editorial rules · Last generated Jul 11, 2026

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.

Herbal Secrets Flaxseed Oil is a liquid supplement with five ingredients. The active components are oleic acid, alpha-linolenic acid, linolenic acid, polyunsaturated fat, and monounsaturated fat — the fatty acids that give flaxseed oil its nutritional profile.

The product also contains flaxseed oil itself as an inactive ingredient (the base of the supplement).

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 key fatty acids in this product, is rated possibly effective for high cholesterol (hypercholesterolemia) and coronary heart disease. We don't have effectiveness data in our records for the other ingredients in this particular 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 you eat it in normal food amounts — think olive oil in cooking or salad dressing. At concentrated supplement doses, though, there isn't good safety data, especially during pregnancy and breastfeeding.

The amounts in food are fine, but we don't know enough about supplement-level doses to say they're safe during pregnancy or nursing. Talk with your doctor or pharmacist if you're pregnant, breastfeeding, or planning either.

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 (insulin, metformin, sulfonylureas, or similar), let your pharmacist know before you start this product — oleic acid may increase their blood-sugar-lowering effects. We couldn't check the other ingredients in this product for interactions, so run your exact medications through the search tool on this page.

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.

If you're looking to support heart health with a flaxseed supplement, this product contains ingredients that have some evidence behind them. But if you take diabetes medications or blood sugar management drugs, ask your pharmacist to check your specific prescriptions first — oleic acid might lower your blood sugar further.

Pregnant or breastfeeding? Check with your doctor before starting.

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.

Flaxseed Oil by Herbal Secrets: Common Questions

Does Flaxseed Oil by Herbal Secrets interact with any medications?
Yes. Based on its ingredients, Flaxseed 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?
Flaxseed 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.
What's flaxseed oil actually used for?
The oleic acid in flaxseed oil has some preliminary evidence for supporting heart health — specifically for high cholesterol and coronary heart disease. That said, we only have effectiveness data for that one component, not the product as a whole.
Is it okay to take this while pregnant or breastfeeding?
Food amounts of oleic acid are considered safe, but supplement-level doses haven't been well studied in pregnancy or breastfeeding. There isn't enough data to say either way, so talk with your doctor or pharmacist for personalized advice before you start.
Can this lower my blood sugar if I'm diabetic?
Possibly. Oleic acid may increase the effects of antidiabetes drugs like insulin or oral hypoglycemic medications. If you manage diabetes, ask your pharmacist to check whether this product could affect your current treatment plan.
Does this product have any fillers or other junk in it?
The product is made of flaxseed oil as its inactive ingredient — which is the base of a liquid supplement. We don't have a complete list of other additives or preservatives that might be in it, so check the label or ask the manufacturer for the full ingredient list.
What are polyunsaturated and monounsaturated fats?
They're both types of healthy fats found in flaxseed oil. We don't have interaction data for them in our system, so we can't say whether they interact with any medications, but they're considered beneficial fatty acids from a nutrition standpoint.
