Mixed
Creatine supplementation significantly improves sprint speed in athletes, while beta-alanine and vitamin D do not.
If your sport relies on short sprints, creatine supplementation combined with training is likely to improve your speed. Beta-alanine and vitamin D did not show significant benefits for sprint speed in this analysis.
GoodSupportsMEDIUM confidence
Creatine also reduced sprint time (SMD = −0.42, 95% CI − 0.68 to −0.16; SUCRA = 94.57%; moderate-certainty evidence)... By contrast, β-alanine... and vitamin D... did not significantly affect sprint performance.
Why this rating
Evidence is rated 'moderate' certainty for creatine.
