Quick Answer
Blackcurrant Extract Exercise Performance Randomized Trial has evidence relevant to safety, limits, and clinician-discussion contexts, but conclusions should stay close to the cited sources. One representative finding is: 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.
Key Takeaways
- 01Results 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)]
- 02Serum 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)]
- 03In contrast, caffeine-containing treatments were associated with improved sprint performance and lower perceived exertion. [Nanavati K (2026)]
- 04Background/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 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.
