Beta-Alanine and Improved Time to Exhaustion

Research synthesisLow evidenceMixed effect size3 studies · 2 beneficial · 1 neutral · 0 harmful

Across 3 studies, 2 reported beneficial effects on time to exhaustion (one moderate effect size, one small) and 1 reported a neutral small effect. The evidence shows moderate evidence for a beneficial effect, but the effect size is mixed (small to moderate). No consistent dose range or study duration was reported; the most studied population includes adults and women.

Caveats: Evidence base is small (only 3 studies) — conclusions should be considered preliminary. One of the neutral studies examined co-supplementation with creatine, which may not reflect beta-alanine alone. The beneficial effects were observed in meta-analyses of beta-alanine supplementation, but the overall evidence is limited.
