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.

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%).

Standardized mean differences (SMDs) and posterior probabilities (P-scores based on Bayesian ranking) were calculated using random-effects and Bayesian models.

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.
The ISSN position stand (PMID 34503527) reviews single-dose trials at 0.2 to 0.5 g/kg: 0.2 g/kg appears to be the minimum dose that improves performance, 0.3 g/kg the optimum, and 0.4 or 0.5 g/kg add no benefit over 0.3 g/kg while causing more frequent and more severe side effects such as bloating, nausea, vomiting and abdominal pain, so the curve is flat above 0.3 g/kg while side effects rise. The benefit is mainly for high-intensity efforts of 30 seconds to 12 minutes. At 0.3 g/kg, a crossover trial in 14 trained cyclists improved 40 km time trial performance (PMID 39068627), and a meta-analysis found effects on anaerobic but not aerobic metabolism (PMID 33546730).
Rests on two meta-analyses that state the dose range they cover. One (PMID 29546641, 10 studies, single doses or up to 2 weeks of 1 to 6 g a day) found endurance improved (Hedges' g 0.40) and that the dose did not change the size of the effect. The other (PMID 40852891, 23 randomised trials of a single dose, 308 participants) found a small-to-moderate overall gain (g 0.25, I² 61%), no significant dose-response within 1 to 6 g, and rated the certainty low to very low. So the curve is flat from 1 g to 6 g. No minimum, optimal or ceiling dose is set, because neither abstract reports an effect or safety at a single dose within the range.
