HelloPharmacist Scorecard of Premium CLA 3-6-9 by GNC Total Lean

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.

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 6 of its 6 active ingredients.
  • No proprietary blends here — you can verify the dose of every single component.

GNC Total Lean Premium CLA 3-6-9 contains 6 active ingredients: conjugated linoleic acid, eicosapentaenoic acid (a type of omega-3 fatty acid), docosahexaenoic acid (another omega-3), gamma-linolenic acid, MCT (medium-chain triglycerides), and oleic acid. These are all fatty acids intended to support body composition and cardiovascular health.

The softgel also contains inactive ingredients: gelatin (the capsule), glycerin, rosemary extract, and mixed tocopherols (a form of vitamin E used as a preservative).

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: body composition, lean muscle, energy, cardiovascular and joint health.
  • We looked for evidence on: Obesity, Coronary heart disease (CHD), Hypertension, Hypercholesterolemia, Stroke, Weight management — and 2 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, Obesity, Stroke.

Oleic acid, one of the six active ingredients here, is rated possibly effective for high cholesterol and coronary heart disease based on preliminary research. The effectiveness of the other five ingredients—conjugated linoleic acid, eicosapentaenoic acid, docosahexaenoic acid, gamma-linolenic acid, and MCT—is not established in the data we hold.

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 from food sources like olive oil is generally recognized as safe. At supplement-level doses, though, safety data is limited, especially in pregnancy and lactation; the amounts studied in pregnancy are not well characterized.

If you're pregnant, nursing, or planning to become pregnant, talk with your doctor or pharmacist before starting this product—we don't have enough data to know if it's appropriate for you. No adverse effects from this product were reported in the data we reviewed.

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 them here before you start—oleic acid in this product may increase their effects and lower your blood sugar more than intended. We have no documented interaction data for the five other active ingredients in this product.

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 product may appeal to you if you're looking to support heart health and body composition with a mix of fatty acids. If you take antidiabetes medication, check your specific drugs with the tool on this page before starting, since oleic acid might boost their effect.

Because we can't verify five of the six ingredients against our drug database, run the full product by your own doctor or pharmacist first.

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.

Premium CLA 3-6-9 by GNC Total Lean: Common Questions

Does Premium CLA 3-6-9 by GNC Total Lean interact with any medications?
Yes. Based on its ingredients, Premium CLA 3-6-9 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?
Premium CLA 3-6-9 contains 6 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 me lose weight or build muscle?
The effectiveness of most of these ingredients—including conjugated linoleic acid and the specific omega-3s in this product—isn't established in the data we hold. Oleic acid is rated possibly effective for cholesterol and heart disease, not weight loss or muscle gain. Talk with your doctor or a registered dietitian about whether this product fits your goals.
Is this safe if I'm pregnant or breastfeeding?
We don't have enough safety data to know whether supplement-level doses of oleic acid are right for pregnancy or lactation. Food amounts are considered safe, but this product is more concentrated. Check with your doctor or pharmacist for personalized advice.
I take medication for type 2 diabetes. Can I use this?
Not without checking first—oleic acid in this product may increase how well your diabetes medication works, which could lower your blood sugar more than expected. Run your specific medication through the checker on this page, then talk with your own doctor or pharmacist before starting.
What's MCT in this product?
MCT stands for medium-chain triglycerides—a type of fat that's absorbed differently than most dietary fats. We don't have interaction or effectiveness data on file for MCT in this product, so we can't tell you what it does here.
Are there any fillers in this?
The active ingredients are the six fatty acids. The inactive ingredients are gelatin (the capsule shell), glycerin, rosemary extract, and mixed tocopherols—these are typical capsule materials and preservatives, not active ingredients.
