Performance evidence brief
Blackcurrant extract is rich in anthocyanins and often promoted for endurance, blood flow, and recovery. Most sport claims are tied to specific New Zealand blackcurrant extracts.
New Zealand blackcurrant extract has a plausible endurance and recovery signal, but trial results vary by sport, dose, and baseline performance.
NZ blackcurrant meta-analysis: performance effect 0.45 (95% CI 0.09-0.81; p=0.01), small but significant.
Studies commonly use anthocyanin-rich extract for about 7 days, but acute, multi-week, and recovery protocols differ.
Product anthocyanin content and the target use case need to match the research closely.

The score reflects evidence that the supplement does its stated job. Some jobs are direct, such as strength, endurance, or recovery; others are indirect, such as sleep, mood, appetite, or health support. A real effect can still receive a cautious practical rating when dose, safety, product quality, or audience fit remain uncertain.
