"Leucine is the only dietary amino acid that has the capacity to stimulate muscle protein synthesis. As a
Leucine potently activates the mammalian target of rapamycin kinase that regulates cell growth. Infusion of leucine into the rat brain has been shown to decrease food intake and body weight via activation of the mTOR pathway.
Leucine toxicity, as seen in decompensated Maple Syrup Urine Disease (MSUD), causes delirium and neurologic compromise, and can be life-threatening."
Leucine is found in most BCAA(Branch Chain Amino Acid) supplements. As animals we must ingest Leucine and do not make it on our own. My favorite BCAA is from Optimum Nutrition and it can be found at http://www.optimumnutrition.com/
Leucine promotes protein synthesis and cell growth, both of which are important to bodybuilders and powerlifters alike. Activation of the mTOR pathway is essential for gains in strength(muscle hypertrophy), and Leucine is vital in in this process.
