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.
The effect of a high-polyphenol Mediterranean diet (Green-MED) combined with physical activity on age-related brain atrophy: the Dietary Intervention Randomized Controlled Trial Polyphenols Unprocessed Study (DIRECT PLUS)
The American journal of clinical nutrition (2022) · Rct · n=284
Among 284 participants (88% men; mean age: 51 y; BMI: 31.2 kg/m2; APOE-ε4 genotype = 15.7%), 224 (79%) completed the trial with eligible whole-brain MRIs.

Effect of the mitophagy inducer urolithin A on age-related immune decline: a randomized, placebo-controlled trial
Nature aging (2025) · Rct · n=50
Exploratory single-cell RNA sequencing demonstrated UA-driven transcriptional shifts across immune populations, modulating pathways linked to inflammation and metabolism.
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.
Based on 3 RCTs (n=88, n=66, n=20) showing improvements in muscle endurance and strength. Effects observed primarily in middle-aged and older adults over 8-16 weeks. Studies used synthetic urolithin A forms with high bioavailability.
AI-estimated from published studies. Interpret as directional guidance.
Taurine has a higher evidence score (7.5/10 vs 6/10) and wins in 1 of 3 categories.
For healthy aging, Urolithin A has a higher relevance score (85 vs 80).
No known interactions between Taurine and Urolithin A have been documented in our database. However, always consult a healthcare provider before combining supplements.
