HelloPharmacist Scorecard of Black Currant Oil by Health From The Sun

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 6 of its 6 active ingredients.
  • No proprietary blends here — you can verify the dose of every single component.

Black Currant Oil contains six active ingredients: gamma-linolenic acid, linoleic acid, oleic acid, alpha-linolenic acid, stearidonic acid, and black currant seed oil itself. These are fatty acids naturally found in black currant seeds.

The product also contains inactive ingredients — gelatin (the capsule), glycerin, and 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: black currant oil omega fatty acids support.
  • We looked for evidence on: Atopic dermatitis (eczema), Coronary heart disease (CHD), Dry eye, Hypercholesterolemia, Hyperlipidemia, Hypertension — 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: Black Currant is rated "Insufficient Reliable Evidence To Rate" for Atopic dermatitis (eczema), Dry eye, Hyperlipidemia, Hypertension, and more.

Oleic acid in this product is rated possibly effective for high cholesterol and coronary heart disease. Black currant seed oil, however, has insufficient evidence to rate for the conditions we've checked — including Alzheimer disease, liver disease, upper respiratory infection, cough, and eczema.

The evidence just isn't established in our data for these uses.

The evidence, ingredient by ingredient Oleic Acid Black Currant

How safe is it?

Well-documented data
Safety Information · database check
Well characterized

Adverse-effect, pregnancy, and general safety data are on file for most of these ingredients.

Why this rating?
  • We hold adverse-effect (side-effect) data for 1 of the 2 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 2 of 2.
  • General safety write-ups exist for 2 of 2.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Black currant seed oil is safe as a food, but concentrated supplements are less studied — the safety notes advise caution with supplement-level doses. In a trial of over 2,000 patients taking black currant seed oil at 1.8 grams twice daily for 6 weeks, a small number reported mild diarrhea within 2–10 days of starting.

Oleic acid from food sources is generally well tolerated, but concentrated supplements lack good safety data. There isn't enough information on file about either ingredient's use in pregnancy or breastfeeding — talk with your doctor or pharmacist about whether this product is right for you if you're pregnant or nursing.

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?
  • 2 of the 2 matched ingredients can interact with medications — Black Currant, Oleic Acid.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; diabetes medications.
  • For scale: 226 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 with your doctor or pharmacist before using this product if you take blood thinners or antiplatelet drugs (like warfarin or aspirin) — black currant seed oil may increase bleeding risk. Also clear it first if you take phenothiazines (antipsychotic medications), as there's a theoretical concern about lowered seizure threshold.

The bottom line

Scorecard at a glanceFully disclosed formula with some supporting evidence for its stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

This product may help with cholesterol and heart health based on its oleic acid content, though the black currant seed oil itself hasn't been well studied for specific conditions. If you take blood thinners, antiplatelet drugs, or antipsychotics, you'll need to check with your doctor or pharmacist before starting — the interactions could affect how your medications work.

For anyone else, a conversation with your own healthcare provider is worthwhile before adding it to your routine.

Black Currant seed Oil2 drug types · 140 drugs

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.

Likelihood Possible Evidence D

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.
