- Essential for healthy function of muscle metabolism.
- Contains leucine, valine and isoleucine in appropriate proportions.
- Immune-stimulant effects.
The branched-chain amino acids (BCAA) leucine, isoleucine and valine are essential amino acids that cannot be produced by the body and must be ingested from the diet. They are the third most important source of energy after carbohydrates and fatty acids. They are essential for healthy muscle metabolism and represent 35% of muscle volume.
Moderate exercise increases the body's leucine needs by 240%. During prolonged exercise, the muscles convert a large proportion of BCAAs to alanine, which is used in hepatic neoglucogenesis. If BCAA concentration becomes too low, the muscle 'self-destructs' in order to provide the missing fuel.
BCAAs therefore play an important role in endurance training. One study showed that 90 days' supplementation with BCAAs and glutamine by a group of rugby players significantly improved post-exercise muscle recovery and also increased stamina:
