L-leucine is a branched-chain amino acid that works along with the other branched-chain amino acids isoleucine and valine to repair and protect muscle.* Leucine also helps promote growth hormone production and may promote the healing of bones, skin, and muscle tissue.* It also may help to regulate blood sugar.* A 2011 study in the Journal of Nutrition found that a higher dietary branched chain amino acid (isoleucine, leucine, and valine) intake is associated with lower prevalence of overweight status/obesity among healthy middle-aged adults from east Asian and western countries.60
