Beta-Alanine
An amino acid studied for buffering fatigue during short, high-intensity exercise.
Evidence category: Systematic review. This describes the source category, not approval or certainty.
Regulatory statement in source: Not separately recorded; do not infer approval from the evidence category.
Beta-alanine is a non-essential amino acid that serves as the rate-limiting substrate for synthesis of carnosine, a muscle dipeptide that buffers hydrogen ions during high-intensity exercise. It is one of the more extensively studied sports supplements, with a substantial meta-analytic literature on muscle carnosine loading and exercise performance.
Benefits reported in the imported source
- Consistent ergogenic effect for high-intensity exercise lasting one to four minutes
- Well-characterized mechanism through increased muscle carnosine concentration
- One of the more extensively replicated effects among sports supplements
Risks and limits
- Little to no benefit shown for exercise shorter than sixty seconds
- Paresthesia (skin tingling) is a common transient side effect at higher single doses
- Effect size is more modest in elite athletes than in recreational populations
Source bottom line: Meta-analytic evidence for a modest but real performance benefit in high-intensity exercise lasting one to four minutes is among the strongest in the sports-supplement category.
Uncertainty: Reference information only. Not medical advice.
Study protocols — reports, not instructions
360 trained and untrained participants across twenty-three exercise tests pooled from fifteen published studies
- Reported regimen
- Eighteen different beta-alanine supplementation regimens, totaling a median of 179 g of beta-alanine across the supplementation period
- Duration
- Supplementation periods varied across the eighteen regimens pooled
- Reported outcome
- Greater improvement in exercise measures than placebo, with the largest benefit for exercise capacity lasting 60 to 240 seconds; a median 2.85 percent improvement in exercise outcome overall

Community and practice descriptions
Accounts of a practice are not evidence of safety or effectiveness. Words such as “standard”, “safe” or “recommended” describe the source account, not verified consensus or this wiki’s advice. Commercial and self-published citations are retained for traceability, not vendor endorsement or independent clinical corroboration.
