Nutrakey Leucine – Helps Preserve Lean Tissue, Stimulates Muscle Protein Synthesis, Stacks Great With Protein!The Building Block For Muscle Protein!Leucine is an essential BCAA. Leucine is an essential amino acid, which simply means our bodies cannot produce it and we must get it from dietary sources. Leucine is the most abundant of the three branched chain amino acids (BCAAs) in muscles (the other two are isoleucine and valine).ANABOLIC AMINO ACIDOne of the primary functions of Leucine is to help preserve lean tissue. This is vital to successful weight loss. Leucine works directly to prevent muscle loss during weight loss. When following a high protein diet high in Leucine, therefore, the majority of weight you lose is fat, not muscle.L-Leucine also stacks well with whey protein or other protein powders, other muscle building products or other fat loss products and just about anything! 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, that cannot be made by the body, and must be acquired through food and dietary supplements. Leucine can be found in foods like nuts, wheat pasta/bread, and brown rice and whey protein powder. Leucine is classified as a branched-chain amino acid (BCAA). It comprises about 8% of the total amino acids in your body’s protein structures and is the fourth most concentrated amino acid in skeletal muscle tissue.STIMULATES MUSCLE PROTEIN SYNTHESISL-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.*BETTER TOGETHERIn 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. Note: Manufacturers continually change product specifications.
