Of all the amino acids that you take in on a daily basis, L-Leucine may just be the most beneficial. It is an essential branched chain amino acid, which means your body cannot make it and you have to get Leucine from your daily diet. Leucine can be found in foods like nuts, wheat pasta/bread, and brown rice and whey protein powder.
L-Leucine is important for both general health as well as athletic performance. If you are trying to transform your body by burning fat and building strong, lean muscle it will make a great addition to your supplement stack. Leucine stimulates muscle protein synthesis and may be the major fuel involved in anabolic (tissue building) reactions. This makes it especially important for body builders and other athletes in sports that demand explosive strength.
In order to see the best intended benefits from L-Leucine, you want to take L-Leucine with other amino acids. Getting a full amino acid profile is going to be key for building lean muscle mass and getting toned. L-Leucine stacks well with L-Valine and L-Isoleucine, the other BCAAs – branched chain amino acids. A good ratio to go for is 2:2:1 – Leucine, Valine, Isoleucine. Many products already blend the BCAAs in this ratio.
