L-Leucine is an essential amino acid, which means the body does not manufacture L-Leucine, and it must be acquired through diet or supplementation. The male adult’s daily requirement is 14 mg per kg of body weight. It is one of the branched chain amino acids, along with L-Isoleucine and L-Valine. Supplementation should be combined with the other two branched chains. Food sources for L-Leucine are meat, almonds, cashews, eggs, fish, chicken, lentils and liver.

L-Leucine possesses two traits not shared by other amino acids. L-Leucine can stimulate insulin release in the absence of glucose and can more than double insulin release in combination with carbohydrates. Higher levels of insulin post-training means faster recovery and accelerated growth.

For those looking for that anabolic edge, scientist recently discovered that L-Leucine targets an anabolic pathway, by acting on the mammalian target of rapamycin (mTOR). The mTOR is one of the most potent positive regulators of growth ever discovered. Leucine acts independently to speed protein synthesis by activating the mTOR pathway.
