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 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 5 active ingredients, all of them fatty acids or fatty acid concentrates. The main active is Conjugated Linoleic Acid (CLA), a fatty acid found naturally in meat and dairy; the formula also includes Oleic Acid (the heart-healthy fat in olive oil), Linoleic Acid, Palmitic Acid, and Safflower Oil Concentrate as a delivery source.

The softgel capsule itself is made from gelatin, glycerin, water, caramel, and carob — these are inactive fillers and binders.

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, Metabolic syndrome, Weight management, Body composition.
  • The closest evidence on file: Oleic Acid is rated "Insufficient Reliable Evidence To Rate" for Obesity (Natural Medicines).

Oleic acid, one of the active ingredients here, is rated Possibly Effective for lowering cholesterol and for heart disease risk. The evidence base we hold doesn't establish ratings for the other active ingredients in this formula, including Conjugated Linoleic Acid itself, so we can't tell you from our data whether CLA lives up to its workout or body-composition claims.

Talk with your pharmacist about what the current research says for your specific goal.

The evidence, ingredient by ingredient Safflower 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 in normal amounts. When it comes to concentrated supplement doses during pregnancy or while breastfeeding, the safety data we hold isn't robust enough to say either way.

If you're pregnant, nursing, or planning to become pregnant, chat with your doctor or pharmacist about whether this product is right for you. No adverse effects are documented in our data for the ingredients we reviewed.

Side effects, ingredient by ingredient Safflower 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 — oral medications that lower blood sugar — double-check them in our interaction checker before using CLA. The oleic acid in this product may increase their effect, which could lower your blood sugar more than intended.

No other medication interactions are documented for the ingredients we could check.

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.

CLA may interest athletes and fitness enthusiasts looking to support body composition. If you take diabetes medications, check your specific drugs with our tool before you start — oleic acid can strengthen their blood-sugar-lowering effect.

Pregnant or nursing? Talk with your pharmacist first, since concentrated doses of these fatty acids haven't been well studied in those settings.

For personalized guidance, your pharmacist is the best resource.

Formula

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. CLA, when used in conjunction with a regimented diet and exercise plan, helps you get the muscle tone you want. CLA can also be stacked with additional weight management products.

Ingredients driving the most interactions

Each ingredient & the kinds of drugs it affects

For each ingredient in CLA with known interactions, here are the types of medications it can affect. Open any type for the detail — or search your exact drug in the checker above.

Safflower Oil Concentrate3 drug types · 208 drugs

Anticoagulant/Antiplatelet Drugs

High doses of safflower oil might increase the risk of bleeding when taken with anticoagulant or antiplatelet drugs.
Small clinical studies show that taking safflower oil, approximately 55 grams daily for 2-3 weeks, decreases platelet aggregation. However, taking lower doses of safflower oil, such as 5 grams daily for 4 weeks, does not seem to affect platelet function. In one case report, a 74-year-old male stabilized on warfarin developed urinary tract bleeding and an elevated INR after taking a safflower extract 20 grams daily for 14 days.

Likelihood Possible Evidence B
Antidiabetes Drugs

Theoretically, safflower oil might alter the effects of antidiabetes drugs.
Some clinical research shows that taking safflower oil 10 grams daily for 3 weeks can increase fasting blood glucose in patients with type 2 diabetes. However, clinical research in patients with metabolic syndrome with or without impaired glucose tolerance shows that taking safflower oil 8 grams daily for 12 weeks reduces fasting glucose levels by around 8 mg/dL. Some clinical research also shows that taking safflower oil 8 grams daily for 16 weeks does not affect fasting glucose levels in patients with type 2 diabetes.

Likelihood Possible Evidence B
Warfarin

Theoretically, safflower oil might increase the risk of bleeding when taken with warfarin.
In one case report, a 74-year-old male stabilized on warfarin developed urinary tract bleeding and an elevated INR after taking a safflower extract 20 grams daily for 14 days.

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 208 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
CLA contains a single active ingredient, and that one ingredient can interact with many different medications on its own. We check it against each medication and show the mechanism 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.
Does CLA really help with body composition or fat loss?
Our data doesn't establish whether Conjugated Linoleic Acid itself works for those claims. Oleic acid, which is in this formula, is rated Possibly Effective for cholesterol and heart health — but that's different from body composition. Talk with your pharmacist or check the latest fitness research for what CLA actually does.
Is this safe if I'm pregnant or breastfeeding?
The safety data for concentrated supplement doses of oleic acid during pregnancy and breastfeeding isn't strong enough for us to say it's fine. Food amounts are considered safe, but this is a supplement dose. Chat with your doctor or pharmacist to make an individual call for your situation.
What's in this capsule besides the active ingredients?
The softgel is made with gelatin, glycerin, water, caramel, and carob — these are inactive ingredients that hold everything together and give it color. They're not the active fatty acids doing the work.
I take metformin for type 2 diabetes. Can I use this?
Metformin is one of the antidiabetes drugs that may be affected by oleic acid in this product. Check metformin specifically in our interaction tool on this page, and talk with your pharmacist or doctor before starting — they can decide if you need blood sugar monitoring.
Are there any side effects from this product?
No adverse effects are documented in our data for the ingredients we reviewed. That doesn't guarantee you won't have a reaction, but the safety information we hold doesn't flag any common ones.
