1Fast400 BCAA's are combined in a precise 2:1:1 ratio of Leucine:Isoleucine:Valine. What are BCAA's BCAAs are Branched Chain Amino Acids consisting 3 essential amino acids leucine, isoleucine, and valine. They are considered essential amino acids because human beings cannot survive unless these amino acids are present in the diet. They are called BCAA's because they structurally branch off another chain of atoms instead of forming a line. Together they comprise approx. 13 of human muscle tissue. The BCAA's consist of 3 essential amino acids: leucine, isoleucine, and valine. Studies have shown that BCAA's help to stimulate protein synthesis and inhibit its breakdown, so BCAA's have powerful anabolic and anti-catabolic effects on the body. How Do BCAA'S Work During intense weight training the body is normally in a highly catabolic condition. At this time glycogen stores are being rapidly depleted and the liver in turn must synthesize glucose by a conversion of L-Alanine. Alanine makes up
