HelloPharmacist Scorecard of CLA by OL Olympian Labs Performance Sports Nutrition

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

Low disclosure
Ingredient Transparency · database check
Low

Most active ingredients don't disclose an individual amount — you can't tell how much of each you're getting.

Why this rating?
  • The label discloses an exact amount for 0 of its 5 active ingredients.
  • “Safflower/Sunflower Oil concentrate” is listed as a grouped ingredient — the label gives one combined amount (3 Gram(s)) without saying how much of each component you get.

This product contains five active ingredients: Stearic Acid, Conjugated Linoleic Acid, Oleic Acid, Alpha-Linolenic Acid, and Palmitic Acid — a blend of fatty acids. The inactive ingredients are gelatin, glycerin, water, caramel, and carob; they're the capsule and flavoring, not the active part.

Does it work?

Not established
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
Not established

The graded evidence we hold for these ingredients covers different conditions than the ones this product is marketed for, so there's no established rating for its stated use — see Oleic Acid's own graded uses on its monograph.

Why this rating?
  • The label markets this product for: reduce body fat and increase lean muscle mass.
  • We looked for evidence on: Obesity, weight management, body composition.
  • The closest evidence on file: Oleic Acid is rated "Insufficient Reliable Evidence To Rate" for Obesity (Natural Medicines).

Oleic Acid is rated possibly effective for high cholesterol (hypercholesterolemia) and coronary heart disease based on the data we hold. We don't have effectiveness ratings for the other four active ingredients in this product, so the evidence for their clinical benefit isn't established in our records.

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 in normal food amounts — it's a main component of olive oil. The safety data we hold cautions, though, that concentrated supplement doses haven't been well studied in pregnancy or breastfeeding, so there isn't enough information to know either way.

The ingredient was otherwise well tolerated; no adverse effects are documented in our data.

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 (blood sugar–lowering medications), double-check with your pharmacist before starting this product. The oleic acid in it may increase their effect on blood sugar.

We hold no interaction data for the other four active ingredients, so that's the only interaction we can flag from our records.

Check your own medication Run your meds through the checker above

The bottom line

Scorecard at a glanceFormula with limited ingredient disclosure with no established evidence rating for its marketed use. Moderate medication interactions have been identified, and some safety-information gaps remain.

This product may be worth considering if you're interested in a source of fatty acids for cholesterol or heart health, though the evidence is preliminary. If you take antidiabetes medication, talk it over with your doctor or pharmacist first — the oleic acid in this blend might affect how those drugs work.

For pregnancy or breastfeeding, there isn't enough safety data to know if this concentrated form is right for you; check with your own healthcare provider.

General Statements

CLA (Conjugated Linoleic Acid) is a targeted, stimulant free solution to help maximize your fitness efforts, reduce body fat and increase lean muscle mass. Studies suggest CLA works by increasing your metabolic rate to help burn calories and pushing glucose (blood sugar) into muscle cells instead of letting it turn into body fat.

Olympian Labs, Inc. products are made with the highest quality ingredients and manufactured according to Good Manufacturing Practices (cGMP).

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.

CLA by OL Olympian Labs Performance Sports Nutrition: Common Questions

Does CLA by OL Olympian Labs Performance Sports Nutrition interact with any medications?
Yes. Based on its ingredients, CLA 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?
CLA contains 5 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 product lower my blood sugar?
We don't have clinical evidence showing this CLA product lowers blood sugar itself. Oleic Acid may theoretically increase the effects of antidiabetes drugs you're already taking, which could shift your blood sugar — but that's different from the product doing it on its own. Talk with your doctor or pharmacist about what to expect.
Is it safe to take while I'm pregnant or breastfeeding?
The safety data we hold on Oleic Acid doesn't give us a clear answer — food amounts are fine, but concentrated supplement doses haven't been well studied in pregnancy or breastfeeding. There isn't enough information to know either way, so you'll want to ask your doctor or pharmacist for personalized advice.
What's Conjugated Linoleic Acid and why is it in here?
Conjugated Linoleic Acid is a type of fatty acid — it's the 'CLA' in the product name. We don't hold interaction or effectiveness data for it, so I can't tell you what it's meant to do in this blend or how it interacts with medications.
Does this product have any fillers?
Yes — the inactive ingredients are gelatin, glycerin, water, caramel, and carob. Those are the capsule material and flavoring, not the active ingredients.
Are there any side effects I should know about?
No adverse effects are documented in our data for the ingredients we checked. That doesn't guarantee none will happen, but based on what we hold, you shouldn't expect side effects from these particular components.
