HelloPharmacist Scorecard of Blackcurrant Powder 5000 mg Veg Capsules by BulkSupplements.com

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 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: blackcurrant powder. The powder comes in a vegetable capsule, with hypromellose as an inactive ingredient (a plant-based capsule material).

Does it work?

Couldn't assess
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 assessable

This is a single-ingredient Black Currant product and its label doesn't state a use — see Black Currant's own graded uses on its monograph.

Why this rating?
  • We looked at the product name, claims, and label statements and couldn't find a stated purpose to grade.

The evidence for blackcurrant powder isn't established in our data. We have insufficient reliable evidence to rate its use for Alzheimer disease, liver disease, upper respiratory tract infections, cough, or atopic dermatitis (eczema).

If you're considering it for one of these purposes, talk with your doctor about whether the current evidence supports it for you.

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.

Blackcurrant berries are safe as food, but concentrated supplements like this one are less studied. The data advises caution with supplemental doses — check with your doctor before starting.

In a trial of 2,154 people taking blackcurrant seed oil at 1.8 grams twice daily for 6 weeks, a small number reported mild diarrhea 2–10 days after beginning treatment. Pregnancy and breastfeeding safety data isn't on file for this ingredient.

If you're pregnant or nursing, talk with your doctor or pharmacist before taking it.

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 product, double-check with your doctor or pharmacist if you take blood thinners or blood-clotting preventers (anticoagulants or antiplatelet drugs) — blackcurrant may increase bleeding risk. Also confirm it's safe if you take phenothiazines, an older class of antipsychotic medication.

The bottom line

Scorecard at a glanceFully disclosed formula with no assessable stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

Blackcurrant powder may be worth considering if you're interested in trying it for general wellness, but you'll want to rule out interactions with blood thinners and certain psychiatric medications first. The evidence for specific health conditions isn't established in our data.

Check with your own doctor or pharmacist before starting, especially if you take anticoagulants, antiplatelet drugs, or phenothiazines.

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.

Blackcurrant Powder 5000 mg Veg Capsules by BulkSupplements.com: Common Questions

Does Blackcurrant Powder 5000 mg Veg Capsules by BulkSupplements.com interact with any medications?
Yes. Based on its ingredients, Blackcurrant Powder 5000 mg Veg Capsules 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?
Blackcurrant Powder 5000 mg Veg Capsules 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.
Can I take blackcurrant powder if I'm on a blood thinner like warfarin?
Not without checking first. Blackcurrant contains gamma-linolenic acid, which may increase your bleeding risk when combined with blood thinners or blood-clotting preventers. Talk with your doctor or pharmacist before adding this supplement to your routine.
What are the side effects?
In a large trial, a small number of people reported mild diarrhea within 2–10 days of starting the supplement. Long-term safety data on concentrated blackcurrant supplements is limited, so use caution and mention it to your doctor.
Does blackcurrant powder actually work for anything?
The evidence we have isn't strong enough to rate its effectiveness for the conditions it's promoted for — including Alzheimer disease, liver disease, upper respiratory infections, cough, and eczema. Talk with your doctor about whether blackcurrant is right for what you're hoping to address.
Is it safe to take blackcurrant powder while pregnant or breastfeeding?
We don't have safety data for concentrated blackcurrant supplements during pregnancy or lactation. If you're pregnant or nursing, talk with your doctor or pharmacist before taking this product.
What's in the capsule besides blackcurrant powder?
The capsule itself is made from hypromellose, a plant-based material. There are no other active ingredients — just the blackcurrant powder and the capsule shell.
