Effects of different dietary supplements on athletic performance in soccer players: a systematic review and network meta-analysis
Journal of the International Society of Sports Nutrition (2025) · Meta analysis
Kaempferia parviflora (SMD: 0.46, small) was associated with a significant effect on enhancing muscular strength.
Based on RCTs showing cognitive improvements in healthy adults and dementia patients. Effect sizes were modest and some studies used combination therapy. Higher doses associated with increased headache risk.
Meta-analysis of 1461 subjects showed 2.85% median improvement. Effect size 0.39 overall, with optimal effects at 5.6-6.4g/day. Most effective for 1-4 minute high-intensity efforts. Side effect risk primarily reflects paresthesia (tingling), which is common but harmless.
AI-estimated from published studies. Interpret as directional guidance.
Beta-Alanine has a higher evidence score (7.5/10 vs 7/10) and wins in 3 of 3 categories.
For athletic performance, Beta-Alanine has a higher relevance score (95 vs 60).
No known interactions between Alpha-GPC and Beta-Alanine have been documented in our database. However, always consult a healthcare provider before combining supplements.
