Does Bicarbonate Exercise Performance Meta-Analysis work?

The current Migaku evidence database contains 2 reusable source documents for Bicarbonate Exercise Performance Meta-Analysis. This answer focuses on strength of evidence and what the studies can or cannot prove. - The Effects of Combined Caffeine and Sodium Bicarbonate Supplementation on Exercise Performance, Physiological Responses, and Gastrointestinal Tolerability: A Systematic Review and Meta-Analysis [Chen X (2026); evidence level 1] - However, comparisons among active conditions provided no clear evidence that co-ingestion was superior to either supplement alone. [Liu S (2026); evidence level 1] - SB increased blood pH (g = 0.95) and blood lactate (g = 1.13), whereas caffeine reduced blood bicarbonate (g = -0.89). [Liu S (2026); evidence level 1] - Background : Caffeine and sodium bicarbonate (SB) are widely used ergogenic supplements that influence exercise performance through distinct physiological mechanisms and may differentially modulate exercise-related metabolic responses. [Liu S (2026); evidence level 1] - Whether their co-ingestion provides benefits beyond either supplement alone remains uncertain. [Liu S (2026); evidence level 1] Evidence levels are sorting aids, not final clinical grades. Level 1 usually indicates systematic-review style evidence, level 2 indicates randomized trials or public-health guidance, and lower levels need more cautious wording. This page is educational.
