Beta-alanine is a non-essential amino acid (can be made by the body so it is not necessary to get it from food).
Beta-alanine is used by the body to synthesize Carnosine, a protein building block thought to aid the buffering of acid in muscles. Carnosine, a dipeptide (two amino acids bonded together) helps to neutralize lactic acid and at the same time, increase ATP stores. It is an antioxidant, purported to support cellular rejuvenation and may play a role in healthy aging. It may also improve heart health and wound healing.
Research has shown that Beta-alanine is involved in improving physical performance in that it can enhance muscular endurance during strength training. It also help to increase moderate, to high intensity cardiovascular exercise performance, by reducing fatigue and improving time to exhaustion.
Supplementation with Beta-alanine may help with healing, muscle recovery and muscle contraction.
Some studies have demonstrated that Beta-alanine may delay muscle fatigue in older adults, can aid in fat loss as well as increase lean mass.
How it works:
Beta-alanine's effects are primarily due to boosting the production of Carnosine, an intramuscular dipeptide. It has been seen that when Beta-alanine is ingested, it changes into Carnosine, which in turn, acts as an acid buffer in the muscles. Carnosine is stored in cells and released when body pH drops, helping to keep muscular pH optimum.
