HelloPharmacist Scorecard of Tonalin CLA by Olympian Labs Incorporated

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

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 8 of its 8 active ingredients.
  • “Conjugated Linoleic Acid” is listed as a grouped ingredient — the label gives one combined amount (84 %) without saying how much of each component you get.
  • “Safflower Oil” is listed as a grouped ingredient — the label gives one combined amount (3 g) without saying how much of each component you get.

Tonalin CLA is a softgel supplement built around conjugated linoleic acid (CLA) — a fat found naturally in beef and dairy. This product contains 8 ingredients total, including oleic acid (a monounsaturated fat from sources like olive oil), along with other fatty acids and fat-derived compounds like stearic acid, palmitic acid, alpha-linolenic acid, polyunsaturated fat, monounsaturated fat, and safflower oil.

The inactive ingredients are gelatin, glycerin, water, and caramel color.

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

This product doesn't appear to be marketed for a specific use, so we graded Oleic Acid's overall clinical evidence instead.

Moderate

Some clinical evidence supports Oleic Acid for:

Why this rating?
  • We looked at the product name, claims, and label statements and couldn't find a stated purpose to grade.
  • Since the label doesn't commit to one use, we graded the ingredient's overall clinical evidence instead.
  • On file: Coronary heart disease (CHD) — rated "Possibly Effective" (Natural Medicines).
  • On file: Hypercholesterolemia — rated "Possibly Effective" (Natural Medicines).

Oleic acid, one of the active ingredients here, is possibly effective for high cholesterol and coronary heart disease based on the evidence we hold. The effectiveness of conjugated linoleic acid itself and the other fatty acid components in this product is not established in our data.

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 is generally recognized as safe when consumed in normal food amounts, such as from olive oil. However, concentrated supplement doses of oleic acid are not well studied, and there isn't enough data to know whether supplement-level amounts are safe during pregnancy or breastfeeding — talk with your doctor or pharmacist for personalized advice if you're pregnant, planning to become pregnant, or breastfeeding.

No adverse effects from Tonalin CLA are documented in our data.

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.

The main concern is antidiabetes drugs (medications for type 2 diabetes or blood sugar control) — oleic acid in this product may increase their effects, which could lower your blood sugar more than intended. Check your exact medications with the search tool on this page before you start.

The bottom line

Scorecard at a glanceFully disclosed formula with some supporting evidence behind its ingredients' uses. Moderate medication interactions have been identified, and some safety-information gaps remain.

Tonalin CLA is a conjugated linoleic acid supplement built on oleic acid and other dietary fats. If you take diabetes medication, double-check this product with your pharmacist or doctor first, since oleic acid may increase how those drugs work.

Even if you don't take diabetes drugs, confirm your other medications with the checker below.

Ingredients driving the most interactions

Each ingredient & the kinds of drugs it affects

For each ingredient in Tonalin 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 Oil3 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.

How can one product interact with so many drugs?

Does Tonalin CLA work for weight loss or body composition?
Our data covers the effectiveness of oleic acid in this product for high cholesterol and heart disease — not for weight loss or muscle. Whether conjugated linoleic acid or the other fatty acids in Tonalin CLA affect body composition isn't established in the information we hold.
Is it safe to take while pregnant or breastfeeding?
Oleic acid in normal food amounts is fine during pregnancy and breastfeeding, but concentrated supplement doses aren't well studied. There isn't enough data to know either way for supplement-level amounts, so talk with your doctor or pharmacist for personalized advice.
Will this increase or decrease my blood sugar?
Oleic acid may theoretically increase the effects of diabetes medications, which could lower your blood sugar more. If you take any diabetes drugs, check with your pharmacist or doctor before starting — they can help you monitor your levels or adjust your medication if needed.
What exactly is conjugated linoleic acid (CLA)?
Conjugated linoleic acid is a type of fat naturally found in beef and dairy products. It's the main active ingredient in this supplement.
