Sodium Bicarbonate Treatment and Clinical Outcomes in Chronic Kidney Disease with Metabolic Acidosis: A Meta-Analysis
Clinical journal of the American Society of Nephrology : CJASN (2024) · Meta analysis · n=2037
Fourteen RCTs comprising 2037 patients demonstrated that sodium bicarbonate supplementation significantly improved eGFR (standardized mean difference [SMD], 0.33; 95% confidence interval [CI], 0.03 to 0.63; P = 0.03).

However, no statistically significant effects were identified for the remaining supplements, whether administered individually or in combination.
Effects of Different Dietary Supplements on Swimming Performance: A Systematic Review and Network Meta-Analysis
Nutrients (2024) · Meta analysis
L-arginine (Arg) demonstrated superior performance to the placebo (SMD = -1.66, 95% CI [-2.92, -0.44]), emerging as the most effective intervention for reducing 100 swimming time (SUCRA = 89.5%).
Effects of Nutritional Supplements on Endurance Performance and Subjective Perception in Athletes Exercising in the Heat: A Systematic Review and Network Meta-Analysis
Nutrients (2025) · Meta analysis · n=552
Standardized mean differences (SMDs) and posterior probabilities (P-scores based on Bayesian ranking) were calculated using random-effects and Bayesian models.
Effect of a 12-mo intervention with whey protein powder on cognitive function in older adults with mild cognitive impairment: a randomized controlled trial
The American journal of clinical nutrition (2025) · Rct · n=107
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-analyses showing performance improvements in combat sports and cycling. GI distress is dose-limiting factor. Effects primarily observed in events lasting 1-7 minutes. Individual variation in tolerance is high.
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 7.5/10) and wins in 2 of 3 categories.
For improve endurance, Sodium Bicarbonate has a higher relevance score (90 vs 50).
