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 may help improve performance and reduce neuromuscular fatigue, although the research on cyclists is limited
[1].
To reap the benefits of beta-alanine, take 4-6g per day, split over 2 doses, for 2-4 weeks
[2,
