Beta-alanine might improve athletic performance in cyclists. Beta-alanine is an amino acid supplement and precursor to carnosine -- a compound found in muscles that reduces lactic acid accumulation in the muscles. Research suggests that beta-alanine
beta-alaninemay help improve performance and reduce neuromuscular fatigue, although the research on cyclists is limited .
