HelloPharmacist Scorecard of Olive Oil 1,000 mg by Swanson EFAs

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

Generated from HelloPharmacist’s pharmacist-curated databases and editorial rules · Last generated Aug 27, 2026

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 3 active ingredients.
  • “organic extra Virgin Olive Oil” is listed as a grouped ingredient — the label gives one combined amount (1 Gram(s)) without saying how much of each component you get.
  • “Fatty Acid Profile” is listed as a grouped ingredient — the label doesn't break down how much of each component you get.

This product contains 3 active ingredients from olive oil: Linoleic Acid, Oleic Acid, and Palmitic Acid — a blend of fatty acids that make up the fatty acid profile of extra virgin olive oil. The inactive ingredients are gelatin (the capsule shell), glycerin, and purified water.

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, lipid management.
  • 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.

Oleic acid, the main checked ingredient, is possibly effective for lowering cholesterol (hypercholesterolemia) and supporting heart health (coronary heart disease). The evidence is preliminary, not conclusive.

We have no effectiveness data on file for Linoleic Acid or Palmitic Acid in isolation.

The evidence, ingredient by ingredient Olive

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 in food amounts — like eating olive oil regularly — is generally recognized as safe. However, concentrated supplement doses of olive oil haven't been well studied in pregnancy or while breastfeeding.

If you're pregnant, nursing, or planning to become pregnant, talk with your doctor or pharmacist about whether this supplement is right for you. No adverse effects were documented in the data we hold.

Side effects, ingredient by ingredient Olive

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 (medications that lower blood sugar), check your exact medication with your doctor or pharmacist before starting this product — oleic acid may increase how well your drug works.

The bottom line

Scorecard at a glanceFormula with limited ingredient disclosure with some supporting evidence for its stated purpose. Moderate medication interactions have been identified, and some safety-information gaps remain.

This supplement may help with cholesterol and heart health, but the evidence is preliminary. The main thing to watch is if you take diabetes medications — oleic acid may boost their effect.

Talk with your doctor or pharmacist before starting, especially if you have diabetes or are pregnant or breastfeeding.

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.
