creatine — increases body mass
LikelyGrade B, Likely. Human evidence with one recorded weakness, or capped at B by its design or by unread numbers.Finding“The two-way ANOVA for body mass revealed a main effect of pre–post supplementation (p = 0.035, η2 = 0.28) and a pre–post x group interaction (p = 0.006, η2 = 0.42) with only the Cr group increasing body mass after supplementation by 0.99 ± 0.83 kg (+1.36%, p = 0.007).”

creatine — decreases repeated-sprint performance decrement
LikelyGrade B, Likely. Human evidence with one recorded weakness, or capped at B by its design or by unread numbers.Finding“However, differences between the two groups (group x pre–post interaction, p < 0.017, η2 = 0.34) were found for fatigue index for speed, with the post hoc test revealing a decrease in the average fatigue index of all sprints by 16.2% (from 12.7 ± 3.9% before supplementation to 10.6 ± 3.6% after Cr supplementation, p = 0.003).”

creatine — no detected effect on maximal oxygen uptake
LikelyGrade B, Likely. Human evidence with one recorded weakness, or capped at B by its design or by unread numbers.FindingNull result“No significant effect on VO2max was observed following supplementation (placebo: 60.7 ± 7.8 to 61.9 ± 8.0 mL·kg−1·min−1; Cr: 61.0 ± 4.1 to 60.4 ± 3.8 mL·kg−1·min−1).”
