HelloPharmacist Scorecard of Black Currant Extract by Herbadiet

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

This product is pure black currant fruit extract powder — just one active ingredient. The extract contains gamma-linolenic acid (GLA) and other compounds from the black currant berry, concentrated into powder form.

There are no other inactive ingredients listed.

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: Vision support and natural antioxidant.
  • We looked for evidence on: Dry eye, Eye strain, Visual fatigue, Age-related macular degeneration.
  • The closest evidence on file: Black Currant is rated "Insufficient Reliable Evidence To Rate" for Dry eye (Natural Medicines).

The evidence for black currant extract is thin across the board. We hold data on its use for Alzheimer disease, liver disease, upper respiratory tract infection, cough, and atopic dermatitis (eczema), but in each case the evidence is insufficient to rate whether it actually works.

That doesn't mean it's ineffective — it means the research isn't solid enough yet to say.

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.

Food amounts of black currant berry are considered safe, but concentrated supplements like this powder are much less studied. The facts advise caution and recommend checking with your doctor first before using a supplement form.

In a trial of over 2,000 patients taking black currant seed oil, a small number reported mild diarrhea, which appeared 2 to 10 days after starting. Pregnancy and lactation data isn't on file for this ingredient, so you'll want to talk with your doctor or pharmacist about whether it's right for you 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.

Before taking this supplement, check with your doctor or pharmacist if you're on blood thinners or antiplatelet drugs (warfarin, aspirin, clopidogrel, and others) — black currant may increase bleeding risk. Also confirm the dose if you take antipsychotic medications (phenothiazines), as there's a theoretical concern about seizure threshold.

These are the main medication types to double-check.

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 extract may appeal to you if you're interested in supplements from whole-fruit sources, but the evidence for what it actually does isn't established yet. If you take blood thinners, antiplatelet drugs, or antipsychotics, this one needs a careful check with your own doctor or pharmacist before you start.

The concentrated form is less studied than the berry itself, so clarify the safety profile with your healthcare provider.

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 Extract by Herbadiet: Common Questions

Does Black Currant Extract by Herbadiet interact with any medications?
Yes. Based on its ingredients, Black Currant Extract 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 Extract 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.
Will black currant extract thin my blood?
Black currant contains gamma-linolenic acid (GLA), which has antiplatelet properties — meaning it may have a blood-thinning effect. If you already take a blood thinner or antiplatelet drug, combining them could raise your bleeding risk. Talk to your doctor or pharmacist before adding this supplement.
What side effects has been reported?
In a large trial, a small number of patients reported mild diarrhea when taking black currant seed oil — it showed up 2 to 10 days after starting. Overall, the supplement hasn't been extensively studied for side effects, so concentrated forms should be used cautiously.
Is black currant safe to take if I'm pregnant or breastfeeding?
We don't have safety data on file for black currant during pregnancy or lactation. Talk with your doctor or pharmacist before using this supplement if you're pregnant, planning to become pregnant, or breastfeeding — they can help you decide if it's right for you.
Does black currant actually work for anything?
The evidence we hold doesn't yet support claims about black currant for Alzheimer disease, liver disease, respiratory infection, cough, or eczema — the studies just aren't solid enough to say whether it works. That doesn't mean it's useless, just that more research is needed.
Is the powder form safe?
Food amounts of black currant berry are considered safe, but concentrated supplements like powder are much less studied. The facts advise using caution and checking with your doctor first before taking a supplement form.
