Leucine

Leucine is an essential amino acid and one of the branched-chain amino acids (the others are isoleucine and valine). These work together to protect muscle and act as fuel. They promote the healing of bones, skin, and muscle tissue, and are recommended for those recovering from surgery. Leucine also lowers elevated blood sugar levels, and aids in increasing growth hormone production.

Supplemental L-leucine must be taken in balance with L-isoleucine and L-valine, and it should be taken in moderation, or symptoms of hypoglycemia may result. An excessively high intake of leucine may also contribute to pellagra, and may increase the amount of ammonia present in the body.

Where is it found ?

Natural sources of leucine include brown rice, beans, meat, nuts, soy flour, and whole wheat.

How much to take

Always take in a combination supplement with the following ratio: 1 part L-isoleucine, 2 parts L-leucine and 2 parts L-valine.

Caution

Moderately excessive amounts may result in symptoms of hypoglycemia. Very high levels may result in more ammonia being present in the body and may induce pellagra.
