Life Extension Creatine Capsules
Creatine is naturally produced in the human body from amino acids L-arginine, glycine, and L-methionine primarily in the kidney and liver and transported in the blood to help supply energy to all cells in the body. Creatine is metabolized into phosphocreatine, an important storage form used by the brain, heart, and skeletal muscles. In normal healthy individuals, muscle creatine is replenished at a rate of approximately two grams a day.
