Latest review conclusion

The results of the meta-analysis suggest that creatine supplementation did not significantly alter serum creatinine levels (standardized mean difference = 0.48, 95% confidence interval 0.24-0.73, P = .001, I2 = 22%), and did not alter plasma urea values (standardized mean difference = 1.10, 95% confidence interval 0.34-1.85, P = .004, I2 = 28%). The findings indicate that creatine supplementation does not induce renal damage in the studied amounts and durations.

Latest review conclusion

Foods rich in polyphenols and nitrate provide trivial benefits for endurance exercise performance, although these effects may be food dependent. Highly trained endurance athletes do not appear to benefit from consuming nitrate-rich foods but may benefit from polyphenol consumption. Further research into food sources, dosage and supplementation duration to optimise the ergogenic response to polyphenol consumption is warranted. Further studies should evaluate whether differential sex-based responses to nitrate and polyphenol consumption are attributable to physiological differences or sample siz
