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.
  • “Omega-3 Fatty Acids” is listed as a grouped ingredient — the label gives one combined amount (565 mg) without saying how much of each component you get.
  • “Omega-6 Fatty Acids” is listed as a grouped ingredient — the label gives one combined amount (245 mg) without saying how much of each component you get.
  • “Omega-9 Fatty Acids” is listed as a grouped ingredient — the label gives one combined amount (244 mg) without saying how much of each component you get.

ProEFA-3-6-9 Lemon combines 5 active omega fatty acids — omega-3s (eicosapentaenoic acid and docosahexaenoic acid), omega-6s (gamma-linolenic acid), omega-9s (oleic acid), and other omega-3 fatty acids. The softgel capsule also contains inactive ingredients: purified deep sea fish oil, borage seed oil, natural lemon flavor, vitamin E (D-alpha-tocopherol), and rosemary extract.

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
Moderate

Some clinical evidence supports this product's ingredients for its stated purpose, but it isn't conclusive.

Why this rating?
  • The label markets this product for: heart, brain, and immune support.
  • We looked for evidence on: Cardiovascular disease (CVD), Coronary heart disease (CHD), Hypercholesterolemia, Hyperlipidemia, Hypertension, Age-related cognitive decline — and 4 related terms.
  • The strongest evidence on file: Oleic Acid is rated "Possibly Effective" for Coronary heart disease (CHD) (Natural Medicines).
  • Also on file: Oleic Acid is rated "Possibly Effective" for Hypercholesterolemia.
  • Also on file: Oleic Acid is rated "Insufficient Reliable Evidence To Rate" for Hypertension.

Oleic acid, one of the active ingredients, is rated possibly effective for high cholesterol (hypercholesterolemia) and coronary heart disease. We don't hold effectiveness ratings for the other omega fatty acids in this product, so we can't speak to what the evidence shows for those components.

The evidence, ingredient by ingredient Docosahexaenoic Acid (dha) Omega-6 Fatty Acids 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 consumed in normal amounts from food sources like olive oil. However, concentrated supplement doses haven't been well studied in pregnancy or while breastfeeding — food amounts are considered fine, but supplement-level doses lack good safety data.

Talk with your doctor or pharmacist before taking this product if you're pregnant, planning to become pregnant, or breastfeeding.

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 (blood sugar medication), check with your doctor or pharmacist before starting this product. Oleic acid in ProEFA-3-6-9 may increase the effect of your medication, which could lower your blood sugar more than intended.

Additionally, we could not check several of the omega fatty acids in this product for interactions, so mention all your medications to your healthcare provider.

The bottom line

Scorecard at a glanceFully disclosed formula with some supporting evidence for its stated purpose. Moderate medication interactions have been identified, and some safety-information gaps remain.

This is an omega fatty acid blend that may support cholesterol and heart health, though evidence is preliminary. If you take blood sugar medication, you'll want to check with your doctor or pharmacist first, since oleic acid might increase how those drugs work.

Pregnant or breastfeeding? Same conversation — the supplement dose hasn't been studied well enough in those situations.

Omega-3 Fatty Acids3 drug types · 375 drugs

Anticoagulant/Antiplatelet Drugs

Theoretically, DHA may increase the risk of bleeding if used with anticoagulant or antiplatelet drugs.
Although some clinical evidence suggests that DHA might reduce collagen-stimulated platelet aggregation and thromboxane release, most clinical evidence suggests that DHA alone does not affect blood clotting. However, theoretically, when given in combination with EPA as fish oil, concomitant use with anticoagulant or antiplatelet drugs (including aspirin) might increase risk of bleeding.

Likelihood Unlikely Evidence B
Antidiabetes Drugs

Theoretically, taking DHA with antidiabetes drugs might reduce the effects of these medications.
In people with type 2 diabetes, including those taking oral hypoglycemic medications, DHA seems to increase fasting blood glucose levels.

Likelihood Possible Evidence B
Antihypertensive Drugs

Theoretically, taking DHA with antihypertensive drugs might increase the risk of hypotension.
Fish oils containing DHA can lower blood pressure and might have additive effects in patients treated with antihypertensives; use with caution.

Likelihood Probable Evidence B
Omega-3 Fatty Acids full monograph & interactions

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.

Yes. Based on its ingredients, ProEFA-3-6-9 Lemon has a known interaction with 375 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
ProEFA-3-6-9 Lemon 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 help my cholesterol or heart health?
Oleic acid, one of the active ingredients here, is rated possibly effective for high cholesterol and coronary heart disease based on the evidence we have. That means the research is promising but not yet definitive.
I take diabetes medication. Can I take this?
Don't start this without checking with your doctor or pharmacist first. Oleic acid in this product may increase the effect of your blood sugar medication, which could lower your blood glucose more than expected.
Is it safe to take if I'm pregnant or breastfeeding?
The safety data for concentrated supplement doses in pregnancy and breastfeeding isn't solid yet. Food amounts are considered fine, but this product is a concentrated supplement. Talk with your doctor or pharmacist about whether it's right for you during pregnancy or while breastfeeding.
What are eicosapentaenoic acid and docosahexaenoic acid?
They're omega-3 fatty acids — types of fat your body needs but can't always make on its own. Eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) are the active omega-3s in this product.
Does this product have fillers?
It has inactive ingredients like fish oil, borage seed oil, and rosemary extract in the capsule, which support the delivery of the active omega fatty acids.
