Creatine is a component of skeletal muscle. There is about 95% of the human body's total creatine located in skeletal muscle. It is also present in brain and heart. Creatine is a nitrogenous organic acid naturally produced in the human body (actually in all vertebrate) from amino acids L-arginine, glycine, and L-methionine, major in the kidney and liver. The produced creatine is then transported in the blood for use by muscles and other tissue. In humans and animals, there is about half of stored creatine originated from food, mainly from meat. Vegetarians show lower levels of muscle creatine, since vegetables do not contain creatine, but can get same level after taking creatine. The health benefits of creatine are derived from the mechanism of its role in the ATP (adenosine triphosphate) and ADP (adenosine diphosphate) cycle. ATP is the immediate energy source of muscle works. When muscle works, ATP decomposes to release energy for muscle works, and obtain ADP and one phosphate. Creatine combines with phosphate to get phosphocreatine. In intense muscle works, the fast way to get ATP is the bio reaction between phosphocreatine and ADP. One phosphate is transferred from phosphocreatine to ADP to obtain immediate energy form ATP, and release out creatine. Sufficiently stored creatine is helpful for the energy cycle. 1 full teaspoon of the L-arginine powder is about 5g. You can adjust the serving size for your own purpose, with water or juice.
