Does Blackcurrant Extract Supplementation Exercise Performance Randomized Trial work?

The current Migaku evidence database contains 2 reusable source documents for Blackcurrant Extract Supplementation Exercise Performance Randomized Trial. This answer focuses on strength of evidence and what the studies can or cannot prove. - Results Caffeine intake increased average sprint speed ( p = 0.045, η 2 = 0.345) and reduced sprint time ( p = 0.030, η 2 = 0.463) during the m-LIST protocol. [Nanavati K (2026); evidence level 4] - Serum free fatty acids concentrations increased over time ( p 2 = 0.900), with a significant NZBP × time interaction ( p = 0.005, η 2 = 0.433). [Nanavati K (2026); evidence level 4] - In contrast, caffeine-containing treatments were associated with improved sprint performance and lower perceived exertion. [Nanavati K (2026); evidence level 4] - Background/objectives Consumption of New Zealand blackcurrant extract for 7 days has shown to reduce slowing of sprint speed in recreationally active males. [Nanavati K (2026); evidence level 4] - Previous research examining the ergogenic benefits of blackcurrant supplementation (BC) on exercise performance is contradictory. [Morton LC (2025); evidence level 4] Evidence levels are sorting aids, not final clinical grades. Level 1 usually indicates systematic-review style evidence, level 2 indicates randomized trials or public-health guidance, and lower levels need more cautious wording. This page is educational.
