Beta-alanine is an amino acid needed to maintain levels of carnosine in the muscles. Carnosine is a natural substance whose task is to buffer pH value and maintain acid/base balance for optimal muscle work. A supplement of beta-alanine optimizes levels of carnosine and reduces the build-up of lactic acid in the muscles during physical exertion, increasing maximum capacity and delaying the time to exhaustion. When taken on an empty stomach, some users may experience tingling in the skin (Paresthesia) as well as sometimes even reddening of the skin. This is harmless and transient, but if it is perceived as unpleasant, you should reduce the dose and choose to take it with any carbohydrate-containing drink or food.
