Beta-Alanine is an amino acid and occurs naturally as beta amino acid. The dietary source for beta alanine is obtainable by ingesting sources containing dipeptides and this is obtainable in protein rich foods namely pork, chicken, fish and beef. By ingesting such dipeptide only beta alanine is received in plenty. However, besides the dietary source, bodies can as well synthesize the beta alanine in the liver. Beta alanine increases the muscle mass, muscular strength as well as the anaerobic endurance. Alpha alanine is commonly found in meat, plants, eggs, chicken and dairy products, but the beta alanine is not available so conveniently. Beta alanine is also called sometimes as three aminopropionic acid. Beta alanine helps in promoting the high concentrations of intramuscular carnosine and does not support the protein synthesis as well as enzyme production. Beta alanine sustains optimum output in muscle power and in promoting the body weight. It also promotes high energy levels.

L-Histidine- Histidine is one of the twenty amino acids that are considered to be the building blocks of proteins. This proteinogenic amino acid is believed to be non-essential to adult humans, because at some point, after reaching a certain age, they begin to synthesize it. On the other hand, histidine is an essential amino acid to infants, and needs to be part of their regular diet. The amino acid L-Histidine is identified as a precursor for carnosine and histamine biosynthesis. In research studies it has been proven that histidine supplementation can cause an elevated excretion of zinc in rats, up to six times the normal amount. Humans sometimes use histidine supplementation to artificially raise histamine levels. L-Histidine is identified as playing a role with several trace elements, such as iron, molybdenum, manganese, zinc and copper.
