HelloPharmacist Scorecard of Omega Complex by GNC Triple Strength

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

GNC Triple Strength Omega Complex contains 5 active ingredients: eicosapentaenoic acid and docosahexaenoic acid (both omega-3 fatty acids from fish oil), gamma-linolenic acid (an omega-6 fatty acid), oleic acid (a monounsaturated fat), and alpha-linolenic acid (another omega-3). These are fatty acids that play roles in heart and metabolic health.

The softgels also contain inactive ingredients including additional fish body oil, borage oil, flax seed oil, gelatin, glycerin, olive oil, caramel color, and natural lemon flavor.

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: heart health and cholesterol support.
  • We looked for evidence on: Coronary heart disease (CHD), Hypercholesterolemia, Hypertension, Stroke, cardiovascular health, triglycerides.
  • 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, Stroke.

For oleic acid, the evidence supports it as possibly effective for high cholesterol (hypercholesterolemia) and coronary heart disease. The other three active ingredients we could assess — eicosapentaenoic acid, docosahexaenoic acid, and gamma-linolenic acid — don't have effectiveness ratings in our data, so we can't tell you what the evidence shows for them.

Alpha-linolenic acid also lacks an effectiveness rating on file.

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 you eat normal amounts from foods like olive oil. However, concentrated supplement doses haven't been well studied in pregnancy or during breastfeeding — food amounts are considered okay, but the higher levels in supplements lack solid safety data.

We don't have pregnancy or breastfeeding information for the other ingredients on file. If you're pregnant, nursing, or planning to become pregnant, talk with your doctor or pharmacist before starting this product.

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 medications), double-check with your doctor or pharmacist before using this product — oleic acid may increase their effect, which could lower your blood sugar more than intended. We hold no data on whether the other ingredients interact with medications, so bring your full medication list to the conversation.

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 omega supplement may be worth considering if you're interested in heart and cholesterol health, but if you take antidiabetes medication, you'll want to check with your doctor or pharmacist first because oleic acid might boost how well those drugs work. We couldn't fully assess three of the five active ingredients, so review your complete medication list with your healthcare provider before starting.

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.

Omega Complex by GNC Triple Strength: Common Questions

Does Omega Complex by GNC Triple Strength interact with any medications?
Yes. Based on its ingredients, Omega Complex 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?
Omega Complex 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.
Does this product actually help with cholesterol or heart disease?
Oleic acid in this product is rated possibly effective for both high cholesterol and coronary heart disease. We don't have effectiveness ratings for the other omega ingredients, so the overall benefit depends on the whole formula, not just one component.
Is it safe to take while I'm pregnant or breastfeeding?
We don't have enough safety data for the supplement-level doses during pregnancy or breastfeeding. Food amounts of oleic acid are considered safe, but concentrated supplements haven't been well studied. Talk with your doctor or pharmacist about whether this product is right for you during this time.
What's the difference between the omega ingredients in here?
This product combines omega-3 fatty acids (eicosapentaenoic acid, docosahexaenoic acid, and alpha-linolenic acid), an omega-6 (gamma-linolenic acid), and oleic acid, a monounsaturated fat. They come from different sources — fish oil, borage, flax, and olive — and play different roles in heart and metabolic function.
Can I take this if I'm on diabetes medication?
That's something to check with your doctor or pharmacist first. Oleic acid in this product may make antidiabetes drugs work even better, which could lower your blood sugar more than expected, so your medication might need adjusting.
Are there any fillers or unnecessary ingredients in this?
The active ingredients are the five fatty acids, and the product also contains fish body oil, borage oil, flax seed oil, gelatin, glycerin, olive oil, caramel color, and natural lemon flavor as inactive ingredients — these support the softgel format and taste.
