Leucine

Leucine is an essential amino acid, which cannot be manufactured in the body and is part of the three branched-chain-amino-acids. Supplements and protein powders that contain leucine are used extensively by bodybuilders and other athletes to promote muscle recovery, although it has not produced significant changes in body composition.

Leucine has many beneficial effects on sports performance. It helps preserve lean muscle tissue1, it supplies the body with energy when under stress (i.e. when engaging in athletic activity)2, it preserves muscle glycogen (glucose stored in muscle tissue used to power muscular contraction), it maintains nitrogen balance, and it enhances thinking abilities that can decline as physical activity becomes more intense.3 It also works to heal bone, skin and muscle tissue. Why I mention this is Leucine is also part of a weightloss plan that helps to get your metabolism going and to maintain muscle. You will also have more energy too.
