This non-essential amino acid itself was first isolated in watermelons by Koga and Odake in 1914. It was later identified by Wada in 1930. Through the urea cycle, our bodies change L-citrulline into another amino acid called L-arginine and the chemical nitric oxide. Our bodies also utilize L-citrulline in the production of proteins and in the regulation of blood pressure. L-Citrulline seems to be highly effective in utilizing amino acids, especially branched chain amino acids. Branched chain amino acids are purported to promote healthy muscle mass, decrease fatigue and improve muscle soreness especially following  intense workouts. 

The other non-essential amino acid found in this supplement is Leucine. As a branched chain amino acid, Leucine is necessary for protein synthesis which, in turn, builds lean muscle mass. It also plays an important role in preserving and protecting muscle mass from breakdown, making this an attractive component to any exercise routine. The combination of these two amino acids gives this supplement the extra boost you may be seeking in your individual exercise and dietary program.
