HelloPharmacist Scorecard of Black Currant Seed Oil 600 mg by Solaray

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 1 of its 1 active ingredient.
  • No proprietary blends here — you can verify the dose of every single component.

This product contains one active ingredient: black currant seed oil at 600 mg per softgel. Black currant seed oil is rich in gamma-linolenic acid (GLA), an omega-6 fatty acid.

The softgel is filled with gelatin, glycerin, and water as inactive ingredients to hold and deliver the oil.

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: joint health and skin health.
  • 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 we hold on black currant seed oil isn't strong enough to rate. Studies don't give us reliable data to say whether it works for Alzheimer disease, liver disease, upper respiratory tract infection, cough, or atopic dermatitis (eczema).

If you're considering it for one of these reasons, talk with your pharmacist or doctor about what the research actually shows.

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 seed oil is derived from a berry that's safe to eat as food, but concentrated supplements are less studied and should be used with caution. In one trial of over 2,100 people taking 1.8 grams twice daily for 6 weeks, a small number reported mild diarrhea 2–10 days after starting.

Concentrated supplements lack the safety data we have for the whole berry, so check with your doctor before using 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.

Check your medications if you take anticoagulants or antiplatelet drugs (blood thinners) — this supplement may increase bleeding risk. Also check if you're on phenothiazines (antipsychotics or anti-nausea medications), as there's a theoretical concern about seizure risk.

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 seed oil might be worth considering if you're looking into omega-6 support, but the evidence for specific health conditions isn't established in our data. If you take blood thinners or psychiatric medications like phenothiazines, you'll need to check with your pharmacist first.

The supplement is generally well tolerated, though diarrhea can happen early on.

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 Seed Oil 600 mg by Solaray: Common Questions

Does Black Currant Seed Oil 600 mg by Solaray interact with any medications?
Yes. Based on its ingredients, Black Currant Seed Oil 600 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 Seed Oil 600 mg contains a single active ingredient, and that one ingredient can interact with many different medications on its own. We check it against each medication and show the mechanism 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 is black currant seed oil actually used for?
Black currant seed oil is being studied for several conditions—including Alzheimer disease, liver disease, upper respiratory infections, cough, and eczema—but we don't yet have reliable evidence that it works for any of these. Talk with your pharmacist about whether it fits your goals.
Could this cause diarrhea?
Yes, a small number of people in a large trial reported mild diarrhea, usually starting 2–10 days after they began taking the supplement. It resolved on its own, but it's something to watch for when you first start.
Is it safe to take during pregnancy or while breastfeeding?
We don't have safety data on file for black currant seed oil during pregnancy or lactation. Since concentrated supplements are less studied than the food form, talk with your doctor or pharmacist for personalized advice.
Why is the safety different for the berry versus the supplement?
Eating the berry in normal food amounts is likely fine because that's how people have eaten it for a long time. The concentrated supplement form, though, is studied much less, so we know less about how safe it is on its own.
Does it have fillers or other ingredients I should know about?
The softgel contains gelatin, glycerin, and water to hold and deliver the oil. There are no other active ingredients—just the black currant seed oil itself.
