Black currant (blackcurrant)

Q: Does blackcurrant improve exercise performance?

Results are inconsistent. A 2026 review of 21 crossover trials found a small-to-moderate benefit overall (low certainty), largest in repeated-sprint sports. One 7-day trial in 14 cyclists found a 2.4% faster time trial, but a 2025 trial in 16 cyclists found no effect. Fat burning during exercise rose more consistently.

Q: Does blackcurrant lower blood pressure?

Not clearly. A 2023 meta-analysis of 4 blackcurrant trials (97 people) found no significant drop, although two 7-day trials in 14 older adults each found lower central or resting pressure versus placebo.

Q: Does it affect blood sugar?

Possibly, in small trials. A drink with 600 mg anthocyanins before a high-carbohydrate meal reduced the early glucose and insulin rise, and 8 days of 600 mg/day extract improved insulin sensitivity by 22% in adults with overweight. Single lower doses did not work.

Q: Is blackcurrant studied for glaucoma?

A 24-month trial in 38 patients found less visual field loss when 50 mg/day of blackcurrant anthocyanins was added to eye drops. It is a single small trial.

Q: Is blackcurrant extract safe?

No safety problems were reported in the trial abstracts cited here, but most trials lasted 7 days and few described side effects in detail. A 24-month glaucoma trial of purified anthocyanins found no significant systemic changes, and LactMed describes black currant seed oil as generally well tolerated.

Q: Is black currant seed oil the same as blackcurrant extract?

No. Seed oil is a fatty oil containing gamma-linolenic and alpha-linolenic acids, while the trials on this page used berry extracts, powder or purified anthocyanins. LactMed describes the seed oil as generally well tolerated.

Q: What is New Zealand blackcurrant extract?

A concentrated extract of Ribes nigrum berries; the version used in most trials (CurraNZ) provided 105 mg anthocyanins per 300 mg capsule.

Also called blackcurrant, cassis, Ribes nigrum, New Zealand blackcurrant extract, NZBC, CurraNZ (brand).

The short answer

From 15 sources

Black currant is an anthocyanin-rich berry sold mainly as New Zealand blackcurrant extract. A 2026 meta-analysis of 15 small trials found more fat burned during exercise, but performance results are inconsistent and pooled trials showed no significant blood pressure drop. Small trials report better insulin sensitivity and muscle recovery. Most exercise studies used one commercial extract.

Key facts

Sports performance: A 2026 review of 21 crossover trials found a small-to-moderate benefit (d = 0.44, low certainty), largest in repeated-sprint sports; a 2025 trial in 16 trained cyclists found none^14,13,1
Fat burning in exercise: Fat oxidation rose 0.042 g/min across 15 trials (226 active adults)⁹
Recovery: Faster strength recovery and less soreness after arm exercise at 3 g/day in 27 adults, but no effect after a half-marathon in 20 runners^11,2
Blood pressure: Pooled blackcurrant trials (97 people) showed no significant drop; two 7-day crossover trials in 14 older adults each found lower central or resting pressure^10,3,4
Trial size: Single trials cited here enrolled 13 to 40 people; the largest pooled analysis covered 226 people^12,7,9
One product: Most exercise and older-adult trials used the same commercial extract (CurraNZ)^1,2,4

What it is

Black currant (Ribes nigrum) is a dark berry rich in anthocyanins, sold as juice, powder and concentrated extracts such as New Zealand blackcurrant extract.

How it works

Proposed

Blackcurrants are rich in anthocyanins. Trial authors propose that anthocyanin-induced widening of blood vessels raises peripheral blood flow, which could affect exercise and blood pressure, and that a high-dose extract blunts the post-meal glucose and incretin (GIP) response. These mechanisms are not confirmed.^1,5

What the numbers add up to

Each point is worked out from the data and the sources numbered on this page, with the arithmetic shown under it. It adds no new data and is not medical advice.

Small effects in small trials

The performance and blood-pressure findings come from crossover trials of 14 people each over 7 days, and a half-marathon recovery trial found no benefit.^1,2,3,4

Dose matters for blood sugar

Only the highest of three anthocyanin doses changed post-meal glucose, so lower-dose products may not reproduce the effect.⁵

Studied doses

Doses used in research, shown against the official limits. They describe the studies, not a recommendation for you.

Studied doses in research, not advice. These are amounts used in research, not personal advice. Your clinician or pharmacist can say what fits you.

Doses studied in human trials

Doses studied in human trials ranged from 300 mg/day of New Zealand blackcurrant extract (105 mg anthocyanins) for 7 days to 3 g/day of extract for 12 days in a muscle-damage trial; 784 mg/day of blackcurrant powder was given for 6 months. A glaucoma trial used 50 mg/day of purified blackcurrant anthocyanins for 24 months. These are research doses, not recommendations.^1,11,7,6

Who should be careful

4 groups

People on blood pressure medicines: Seven days of extract lowered resting and central blood pressure in older adults; combined effects with blood pressure drugs were not studied.^3,4
People on glucose-lowering medicines: A drink with 600 mg anthocyanins lowered early post-meal glucose and insulin, and 8 days of 600 mg/day extract improved insulin sensitivity; use alongside diabetes drugs was not tested.^5,12
People with glaucoma: The 24-month anthocyanin trial added blackcurrant to standard glaucoma eye drops; it does not replace them.⁶
Pregnancy and breastfeeding: No trial of blackcurrant berry extract cited here enrolled pregnant or breastfeeding women. LactMed covers black currant seed oil, a different product rich in gamma-linolenic acid: it is generally well tolerated, and in one trial 3 g/day from early pregnancy through breastfeeding changed immune markers in breast milk. LactMed has no data on berry extracts.^8,1,7

Extract vs anthocyanin dose

Labels may list extract weight or anthocyanin content. The cycling trial used 300 mg of extract providing 105 mg anthocyanins; the glucose effect appeared only at 600 mg anthocyanins.^1,5

Whole berry products

Trials used concentrated extracts, purified anthocyanins or powder, so results may not apply to juice or jam.^1,6,7
