The results also found a significant beneficial effect of the active intervention for several secondary cognitive outcomes such as Digit Symbol Substitution Test score, and the mean difference between groups in the ITT analysis was 2.72 (95% CI: 0.20, 5.23).
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-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.
Taurine has a higher evidence score (7.5/10 vs 7/10) and wins in 3 of 3 categories.
