HelloPharmacist Scorecard of CLA Conjugated Linoleic Acid by Millecor

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 5 of its 5 active ingredients.
  • “Conjugated Linoleic Acid” is listed as a grouped ingredient — the label gives one combined amount (1,000 mg) without saying how much of each component you get.

This softgel contains five active ingredients, all fatty acids: Stearic Acid, Conjugated Linoleic Acid (CLA), Linoleic Acid, Oleic Acid, and Palmitic Acid. These are all naturally occurring fats found in foods and animal products.

The product also contains inactive ingredients — gelatin (the softgel shell), glycerin, and purified water — which help deliver and stabilize the active ingredients.

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: reduce fat deposits, aid weight loss, support immune and heart health.
  • We looked for evidence on: Obesity, Coronary heart disease (CHD), Hypercholesterolemia, Hypertension, 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 active ingredients here, is rated Possibly Effective for high cholesterol (hypercholesterolemia) and coronary heart disease. We don't have established effectiveness ratings for the other four fatty acids in this product.

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 in the amounts you'd get from everyday foods like olive oil. However, concentrated supplements at higher doses haven't been well studied.

If you're pregnant or 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 nursing.

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 an antidiabetes drug (a Moderate interaction with Oleic Acid), check your specific medication in the tool below. We could not check the other four active ingredients — Stearic Acid, Conjugated Linoleic Acid, Linoleic Acid, and Palmitic Acid — against our database, so if you're on any other prescription drugs, use the checker to be sure.

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 is a blend of fatty acids; one of them (Oleic Acid) may modestly boost the effects of diabetes medications. If you take a drug to lower blood sugar, check it against our medication database before starting.

For other medications, we couldn't evaluate most of the ingredients, so run them through the checker as well. Talk with your pharmacist if you're pregnant or nursing.

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.
