The Claim
Beta-alanine supplementation produces a greater ergogenic effect on Yo-Yo level 2 performance compared to caffeine or sodium bicarbonate supplementation in human athletes.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Beta-alanine improves Yo-Yo level 2 performance more than caffeine or sodium bicarbonate in athletes.
See the scientific wording
The ergogenic effect of beta-alanine on Yo-Yo level 2 performance is larger than that of caffeine or sodium bicarbonate, suggesting it may be among the most effective supplements for high-intensity intermittent sports.
Taking beta-alanine lets muscles make more carnosine, which soaks up acid that builds up during hard, stop-and-go exercise. This keeps the muscle environment less acidic, so the muscles can keep working hard longer without getting tired.
What the research says
1 studyStudy: Effects of beta-alanine supplementation on Yo-Yo test performance: A meta-analysis.
This study shows that taking beta-alanine for 6–12 weeks helps athletes do better in intense, stop-and-go sports like soccer or basketball. It doesn’t compare it to caffeine or baking soda, but the improvement it found is big and real.
