BCAAs

What are Branched Chain Amino Acids (BCAAs)?
Branched Chain Amino Acids, so named because of their unique branching structure, are essential amino acids, which means that the body alone cannot produce them. Therefore sufficient quantities must be obtained from dietary sources. The three BCAAs (Valine, Leucine, and Isoleucine) make up approximately 70 percent of amino acids in the body proteins.

Benefits of BCAAs
BCAAs are unique in that they are metabolized directly by muscle tissue. During prolonged workouts, BCAAs are burned as fuel to provide as much as 15% of your total energy requirement. Since your body only has a limited store of these essential amino acids, it is forced to break down lean muscle tissue when dietary sources aren't meeting your needs. Consuming sufficient BCAAs before and after training helps to prevent training-induced muscle breakdown thereby improving recovery times. BCAAs may also play a key role in delaying fatigue so you can push yourself harder, faster, and longer through the most intense training bouts and competitive events.
