Leucine helps with the regulation of blood-sugar levels, the growth and repair of muscle tissue (such as bones, skin and muscles), growth hormone production, wound healing as well as energy regulation.
Leucine can assist to prevent the breakdown of muscle proteins that sometimes occur after trauma or severe stress. It may also be beneficial for individuals with phenylketonuria – a condition in which the body cannot metabolize the amino acid phenylalanine.
What it is
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.
What it does
Leucine works with Isoleucine and Valine to promote the healing of muscle tissue, skin, and bones. It is recommended for those recovering from surgery. It lowers blood sugar levels. It aids in increasing growth hormone production.

Young adults need about 31 mg of this amino acid per day per kilogram (14 mg per lb) of body weight. Therapeutic use of leucine occurs at doses between 500 and 1,000 mg per day.
