HelloPharmacist Scorecard of Black Currant Oil 500 mg by The Vitamin Shoppe

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 Jul 16, 2026

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.
  • “Black Currant Oil” is listed as a grouped ingredient — the label gives one combined amount (500 mg) without saying how much of each component you get.

Black Currant Oil 500 mg delivers five active fatty acid components: gamma-linolenic acid, linoleic acid, oleic acid, alpha-linolenic acid, and stearidonic acid. These are omega fatty acids naturally present in black currant seed oil, and the product is formulated in a softgel capsule with gelatin, glycerin, and purified water as inactive ingredients.

Does it work?

Couldn't assess
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 assessable

We hold no graded evidence for this product's ingredients for its stated purpose.

Why this rating?
  • The label markets this product for: Women's health and healthy skin.
  • We looked for evidence on: Atopic dermatitis (eczema), Dysmenorrhea, Menopausal symptoms, Premenstrual syndrome (PMS), Joint inflammation, Dry skin — and 2 related terms.
  • Our graded evidence for these ingredients doesn't cover that particular purpose.

Oleic acid, one of the active ingredients here, is rated possibly effective for high cholesterol and coronary heart disease. Evidence for the other fatty acid components — gamma-linolenic acid, linoleic acid, alpha-linolenic acid, and stearidonic acid — isn't established in the data we hold.

The evidence, ingredient by ingredient Black Currant 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 eaten in normal food amounts, like from olive oil. Concentrated supplement doses haven't been well studied in pregnancy or breastfeeding, so the safety data advises caution if you're pregnant or nursing — talk with your doctor or pharmacist about whether this product is right for you.

No adverse effects are documented in our data for this product.

Side effects, ingredient by ingredient Black Currant 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 or blood sugar medications, check them against this product before starting — oleic acid may increase their effects, and your doctor may need to monitor your blood sugar more closely or adjust your dose.

Check your own medication Run your meds through the checker above

The bottom line

Scorecard at a glanceFully disclosed formula with no assessable stated purpose. Moderate medication interactions have been identified, and some safety-information gaps remain.

Black Currant Oil may appeal to you if you're interested in omega fatty acids and possibly effective support for cholesterol and heart health. If you take blood sugar medications, check with your doctor or pharmacist before starting — this product could affect how they work.

Three of the five active ingredients couldn't be checked against our interaction database, so a full review with your own healthcare provider is important.

Anticoagulant/Antiplatelet Drugs

Theoretically, black currant seed oil might increase the risk of bleeding if used in combination with anticoagulant or antiplatelet drugs.
Gamma-linolenic acid (GLA), a constituent of black currant seed oil, appears to have antiplatelet effects.

Likelihood Possible Evidence D
Phenothiazines

Theoretically, black currant seed oil might increase the risk of seizure in patients receiving phenothiazines.
Black currant seed oil contains gamma-linolenic acid (GLA). There is some concern that taking supplements containing GLA might cause seizures, or lower the seizure threshold, when taken with phenothiazines, although there is no evidence that black currant seed oil causes seizures. In one report, three patients with schizophrenia who had received phenothiazines developed EEG changes suggestive of temporal lobe epilepsy after starting treatment with GLA, although none experienced an actual seizure. In another report, two patients with schizophrenia who were stabilized on phenothiazines developed seizures when evening primrose 4 grams daily, which contains GLA, was added. One of these patients had a prior history of seizures.
