Beta-Alanine is a naturally occurring, non-essential amino acid that is gaining popularity as a weight training and bodybuilding supplement.
Studies show that beta-alanine raises muscle carnosine composition. During exercise, beta-alanine produced carnosine assists the body in buffering acid in muscle tissue, delaying fatigue and improving performance.
Beta-alanine is found in protein foods rich in the dipeptides anserine, carnosine and balenine. These foods include fish, chicken, beef and pork. The body can also produce beta-alanine in the liver. Pyrimidine nucleotides are broken down into uracil and thymine, and then converted into beta-alanine.
Current studies indicate that beta-alanine increases muscle mass and strength. It has also been shown that beta-alanine increases aerobic and anaerobic endurance. Simply put, beta-alanine allows you to train longer with more weight.
Beta-alanine appears to be most effective after 10 weeks of continuous supplementation.
