HelloPharmacist Scorecard of Black Currant Oil 1000 mg by NutriONN

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 Oct 1, 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 2 of its 2 active ingredients.
  • No proprietary blends here — you can verify the dose of every single component.

Black Currant Oil 1000 mg contains 2 active ingredients: black currant seed oil and gamma-linolenic acid (GLA). Black currant seed oil is the oil pressed from the seeds of the black currant plant; GLA is a fatty acid that occurs naturally in that oil.

The capsule itself is made from gelatin, glycerin, and purified water.

Does it work?

Not established
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 established

The graded evidence we hold for these ingredients covers different conditions than the ones this product is marketed for, so there's no established rating for its stated use — see Black Currant's own graded uses on its monograph.

Why this rating?
  • The label markets this product for: anti-inflammatory support for various conditions.
  • We looked for evidence on: Atopic dermatitis (eczema), Dry eye, Osteoarthritis, Rheumatoid arthritis (RA), joint inflammation, skin inflammation — and 1 related terms.
  • The closest evidence on file: Black Currant is rated "Insufficient Reliable Evidence To Rate" for Atopic dermatitis (eczema) (Natural Medicines).
  • Also on file: Black Currant is rated "Insufficient Reliable Evidence To Rate" for Dry eye, Osteoarthritis, Rheumatoid arthritis (RA).

The evidence isn't established for any of the conditions this product is marketed for. We have insufficient data on black currant oil for Alzheimer disease, liver disease, upper respiratory tract infection, cough, and atopic dermatitis (eczema).

That doesn't mean it doesn't work — it means the research we have on file isn't strong enough to say either way.

The evidence, ingredient by ingredient 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 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.

Black currant as a food is safe, but concentrated supplements like this one are less studied and should be used carefully. Talk with your doctor before starting a black currant supplement.

In one trial of over 2,000 people taking black currant seed oil 1.8 grams twice daily for 6 weeks, a small number experienced mild diarrhea a few days after starting — the most common side effect reported. We have no pregnancy or lactation safety data on file for this product.

Side effects, ingredient by ingredient Black Currant

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 — Black Currant.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs.
  • For scale: 140 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.

Double-check this product before you start if you take blood thinners (anticoagulants) or antiplatelet drugs like warfarin or clopidogrel — black currant may increase your bleeding risk (Moderate severity). Also check if you take phenothiazines, an older class of antipsychotic medications — there's theoretical concern about seizure risk (Moderate severity).

Altogether, these interactions span 140 individual medications.

The bottom line

Scorecard at a glanceFully disclosed formula with no established evidence rating for its marketed use. Moderate medication interactions have been identified, and safety information is well characterized.

Black currant oil is generally well tolerated, but the concentrated supplement form lacks long-term safety data. If you take blood thinners or seizure medications, check with your doctor or pharmacist before using this product — the interaction risk is real, even if it's theoretical.

For everyone else, it's worth a conversation with your own healthcare provider about whether it fits your needs.

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.

Black Currant Oil 1000 mg by NutriONN: Common Questions

Does Black Currant Oil 1000 mg by NutriONN interact with any medications?
Yes. Based on its ingredients, Black Currant Oil 1000 mg has a known interaction with 140 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Black Currant Oil 1000 mg contains 2 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.
Can I take this if I'm on blood thinners like warfarin?
Not without checking first. Black currant seed oil may increase bleeding risk when combined with blood thinners or antiplatelet drugs. Talk to your doctor or pharmacist before you start — they can tell you whether it's safe for you specifically or if you need to adjust your dosing.
What's gamma-linolenic acid and why is it in here?
Gamma-linolenic acid (GLA) is a fatty acid that occurs naturally in black currant seed oil. It's the oil's active component — the part that's thought to do the work. We don't have separate interaction data for it on file, so if you're concerned about your specific medications, use the checker on this page.
Is this really just black currant, or does it have fillers?
The active ingredients are black currant seed oil and gamma-linolenic acid. The capsule itself contains gelatin, glycerin, and purified water — those are standard capsule materials to hold the oil.
What if I get diarrhea after I start taking it?
Mild diarrhea was the most common side effect in the safety trials we have on file — a small number of people experienced it a few days after starting. If it happens to you, it's usually mild and may go away, but let your pharmacist or doctor know if it's bothersome.
Is it safe in pregnancy?
We don't have pregnancy or lactation safety data on file for this product. If you're pregnant or breastfeeding, talk with your doctor or pharmacist before taking it — they can give you personalized advice based on your situation.
Does black currant oil actually work for the conditions listed?
The evidence isn't strong enough to say. Our data shows insufficient evidence for Alzheimer disease, liver disease, respiratory infections, cough, and eczema. That doesn't mean it won't help you — it means research we hold doesn't support those claims yet.
