Does Black Currant Exercise Performance Meta-Analysis work?

The current Migaku evidence database contains 2 reusable source documents for Black Currant Exercise Performance Meta-Analysis. This answer focuses on strength of evidence and what the studies can or cannot prove. - Polyphenol supplementation was associated with a small improvement in pain/soreness ( g = 0.252, 95% CI 0.049-0.454; p = 0.018). [Hu X (2026); evidence level 1] - Certainty of evidence was low for muscle damage and performance and very low for pain/soreness and perceptual outcomes. [Hu X (2026); evidence level 1] - Conclusion Polyphenol supplementation may modestly reduce post-exercise pain/soreness, but current evidence does not establish consistent improvements in objective recovery, an optimal recovery window, or superiority of any supplementation strategy. [Hu X (2026); evidence level 1] - Background Polyphenol-rich interventions are widely used to support recovery after exercise-induced muscle damage (EIMD), but their effects across outcome domains and recovery periods remain uncertain. [Hu X (2026); evidence level 1] - Methodological quality and risk of bias were assessed using the PEDro scale and Cochrane RoB 2 tool. [Eroglu MN (2026); evidence level 1] 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.
