Beta-Alanine

Also known as: beta alanine, CarnoSyn

Grade A — Strong Evidenceamino acidperformance
3–6 gSplit doses throughout day (to minimize tingling). Full effects after 4-10 weeks of loading.

Beta-alanine is a non-essential amino acid that increases intramuscular carnosine concentrations, buffering hydrogen ions during high-intensity exercise. Meta-analyses consistently show improved exercise capacity for efforts lasting 1-4 minutes, making it particularly valuable for activities like rowing, swimming, and high-rep resistance training. The characteristic tingling sensation (paresthesia) is harmless and can be mitigated by using sustained-release formulations.

TL;DR: Increases muscle carnosine levels, buffering acid during high-intensity exercise. Well-supported for 1-4 min high-intensity efforts.
