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 Jul 11, 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.

This product contains 2 active ingredients per softgel: black currant seed oil and gamma-linolenic acid (GLA). Black currant seed oil is a concentrated extract from black currant seeds, and GLA is a fatty acid naturally found in the oil.

The remaining ingredients — gelatin, glycerin, and purified water — are inactive ingredients that form the softgel capsule itself.

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 health conditions.
  • We looked for evidence on: Atopic dermatitis (eczema), Dry eye, Dysmenorrhea, Gout, Hyperlipidemia, Hypertension — and 4 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, Hyperlipidemia, Hypertension, Osteoarthritis, and more.

The evidence we hold on black currant seed oil is insufficient to rate it for the conditions it's marketed for, including Alzheimer disease, liver disease, upper respiratory tract infection, cough, and atopic dermatitis (eczema). That means the research backing isn't established enough yet for us to say whether it works for these uses.

Talk with your pharmacist about what the current evidence actually supports if you're considering it for a specific reason.

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 generally well tolerated, but concentrated supplements like this one are less well studied. The safety data available is limited, so it's worth checking with your doctor before starting.

In a trial of people taking black currant seed oil at twice the dose in this product for 6 weeks, a small number reported mild diarrhea a few days after starting — it was mild and appeared to resolve. No pregnancy or lactation safety data is on file for this product; talk with your pharmacist or doctor for personalized advice if you're pregnant or breastfeeding.

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.

Check before starting if you take any blood thinners or antiplatelet drugs (warfarin, aspirin, clopidogrel, and others) — black currant oil may increase bleeding risk. Also double-check if you're on phenothiazines (antipsychotic medications) — there's a theoretical concern about seizure risk.

Use the interaction checker on this page with your specific medications for certainty.

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 might appeal to you if you're interested in natural supplements, but the evidence for specific uses isn't strong enough to rate. If you take blood thinners, antiplatelet drugs, or antipsychotic medications, you need to check with your pharmacist first — interactions are documented.

Even without those medications, chat with your doctor before starting, since concentrated supplements haven't been studied as thoroughly as the berry itself.

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.
What are the actual active ingredients in this black currant oil supplement?
This product has two active ingredients: black currant seed oil itself and gamma-linolenic acid (GLA), which is a natural component of the oil. The rest — gelatin, glycerin, and water — are just the capsule material.
Does black currant oil really work for cough, Alzheimer disease, or eczema?
We don't have enough reliable evidence to say either way on those uses. The research isn't established enough in our data to rate it, so you'd want to talk with your doctor about what the current science actually shows before relying on it for any specific condition.
What side effects did people experience when taking this supplement?
In one trial, a small number of people taking a higher dose reported mild diarrhea a few days after starting. That's the main adverse effect we have data on. Most people didn't report problems, but concentrated supplements haven't been studied as widely as the berry itself.
Is it safe to take black currant oil if I'm pregnant or breastfeeding?
We don't have safety data on file for pregnancy or breastfeeding. Since food amounts of the berry are probably fine but concentrated supplements are less studied, talk with your pharmacist or doctor for personalized advice if you're pregnant, planning to be, or nursing.
Can I take this with my blood thinner?
That's something you need to check with your pharmacist before starting. Black currant oil may increase the risk of bleeding when combined with blood thinners or antiplatelet drugs. Use the interaction checker below with your specific medication to be sure.
