Caffeine and taurine: a systematic review and network meta-analysis of their individual and combined effects on physical capacity, cognitive function, and physiological markers
Journal of the International Society of Sports Nutrition (2025) · Meta analysis
Posterior estimates indicated that CAF+TAU was associated with a credible positive effect on anaerobic capacity (g = 0.46, 95% CrI [0.19, 0.71]) and reaction time (g = 0.75, 95% CrI [0.29, 1.18]) compared to CAF or TAU alone.
Based on meta-analyses showing 7-12 minute reduction in sleep onset. Higher doses showed diminishing returns and increased morning grogginess. Sublingual forms may be more effective at lower doses.
Based on meta-analysis showing small-to-moderate effects (g=0.25). Conservative estimates due to high heterogeneity (I²=61%) and mixed study quality. Effects primarily seen in anaerobic capacity and reaction time when combined with caffeine.
AI-estimated from published studies. Interpret as directional guidance.
