Beta-alanine is considered as a non-essential amino acid as this also helps in the production of carnosine which is vital in muscle endurance in times of vigorous activity. According to some studies, this has the potential to increase concentration of carnosine in muscle which acts as an intracellular buffer of pH. Carnosine supplementation appears to be safe and well tolerated by healthy subjects at the recommended levels, with the exception of paresthesia as a common side effect. There is evidence that it can be effective in promoting performance in activities where duration ranges from 1 to over 4 minutes but not in activities where duration is less than 60 seconds duration.
