Beta-alanine

General description of the supplement
Beta-alanine is a non-essential amino acid. It can be synthesized in the body by breaking down pyrimidine nucleotides or we can get it from our diets via carnosine, enserine or balenine. Beta-alanine can enter a muscle cell and increase carnosine levels, which leads to enhanced intracellular buffering and reduced acid accumulation during exercise. The results of beta-alanine supplementation may be improvement in performance, greater training adaptation and faster healing, muscle recovery and muscle contraction.

Claims being made
Beta alanine is an amino acid that is claimed to raise muscle carnosine and increase the amount of work you can perform at high intensities. Many advertisements are selling the beta-alanine supplement as a newcomer that reduces symptoms of fatigue. They suggest the supplement is very beneficial during high intensity weight lifting or sprinting.
Many websites selling the beta-alanine products have listed researches that support the claims but most of the researches do not have the studies cited. That is a example of earmark of quackery where the sellers in order to sell the product make up a research and create the results that attract costumers and convince them to believe that supplement is effective.
Knowing from human physiology, intramuscular acidosis has been one of the main reasons of fatigue during the high intensity exercises. Carnosine, which is synthesized from in skeletal muscles from l-histidine and beta-alanine, on the other hand has been shown to be the main regulator of muscle pH. Availability of beta-alanine is the rate-limiting factor of carnosine synthesis and therefore the beta-alanine supplementation has been shown to increase the amount of muscle carnosine and thus the total muscle buffer capacity. The results are shown to have a potential for improvements in
