HelloPharmacist Scorecard of Complete Omega Lemon by Nordic Naturals

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.
  • “Omega-6 Fatty Acids” is listed as a grouped ingredient — the label gives one combined amount (500 mg) without saying how much of each component you get.
  • “Omega-9 Fatty Acids” is listed as a grouped ingredient — the label gives one combined amount (500 mg) without saying how much of each component you get.
  • “Total Omega-3 Fatty Acids” is listed as a grouped ingredient — the label gives one combined amount (1,270 mg) without saying how much of each component you get.

Complete Omega Lemon is a liquid supplement with 5 active ingredients: eicosapentaenoic acid and docosahexaenoic acid (two key omega-3 fatty acids), gamma-linolenic acid (an omega-6 fat), oleic acid (an omega-9 fat), and other omega-3 compounds. The formula also contains inactive ingredients — purified deep sea fish oil, borage seed oil, lemon flavoring, vitamin E (D-alpha-tocopherol), and rosemary extract — that support stability and taste.

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: Supports skin, mood, cognitive function, and joints.
  • We looked for evidence on: Age-related cognitive decline, Depression, Cardiovascular disease (CVD), Coronary heart disease (CHD), Hypercholesterolemia, Hyperlipidemia — and 4 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 Depression, Hypertension, Stroke.

The only ingredient in this product for which we have effectiveness data is oleic acid, which is possibly effective for high cholesterol (hypercholesterolemia) and for supporting heart health in coronary heart disease. For the other active ingredients — the various omega-3 and omega-6 fatty acids that make up the bulk of the supplement — we hold no effectiveness ratings in our data.

That doesn't mean they're ineffective; it means the evidence we have on file isn't established for those specific compounds in supplement form.

The evidence, ingredient by ingredient Omega-6 Fatty Acids 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, the one ingredient we have safety data for, is generally recognized as safe when you eat it in normal food amounts — like the amount in olive oil. However, concentrated supplement doses of oleic acid haven't been well studied.

The safety data we hold advises caution with supplement-level doses in pregnancy and while breastfeeding. We have no adverse effects on record for oleic acid itself, though you should watch for signs of low blood sugar if you take antidiabetes medications alongside this product.

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.

Check your antidiabetes medications (pills or insulin that lower blood sugar) before taking this product — oleic acid may increase their effect and raise the risk of low blood sugar. We could not verify interactions for most of the omega fatty acids in this supplement, so run your full medication list through the checker on this page 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 is an omega supplement that supplies several types of fatty acids. If you take diabetes medication, check with your doctor or pharmacist first — oleic acid in this product may strengthen those drugs' blood-sugar-lowering effect.

For pregnancy, breastfeeding, or any personal health question about whether this is right for you, talk it over with your own healthcare provider before you start.

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.

Complete Omega Lemon by Nordic Naturals: Common Questions

Does Complete Omega Lemon by Nordic Naturals interact with any medications?
Yes. Based on its ingredients, Complete Omega Lemon 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?
Complete Omega Lemon 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.
What are the omega fatty acids in this product?
This supplement contains eicosapentaenoic acid and docosahexaenoic acid (two forms of omega-3), gamma-linolenic acid (omega-6), oleic acid (omega-9), and other omega-3 compounds. The source is deep sea fish oil and borage seed oil.
Does oleic acid really lower cholesterol?
The research we have on file shows oleic acid is possibly effective for high cholesterol and for heart disease support. That's based on its known effects when eaten in foods like olive oil, though concentrated supplement doses haven't been as thoroughly studied.
Is it safe to take this if I'm pregnant or breastfeeding?
Oleic acid in normal food amounts is considered safe during pregnancy and breastfeeding, but concentrated supplement doses haven't been studied well enough to know for sure either way. Talk with your doctor or pharmacist about whether this product is right for you right now.
Can this lower my blood sugar too much if I take diabetes medication?
Yes — that's a real concern. Research suggests oleic acid may strengthen the blood-sugar-lowering effect of antidiabetes drugs, which could increase your risk of low blood sugar. Check with your doctor or pharmacist before starting this supplement so they can monitor you and adjust your medication if needed.
Are there any side effects listed for this product?
We have no adverse effects on record for the omega fatty acids in this supplement. That said, we weren't able to check interaction or safety data for most of its active ingredients, so if you have questions about how you personally might react, talk with your pharmacist.
