Message: | Creatine is a naturally occurring amino acid (protein building block) found mainly in muscles. Fifty percent of creatine in our bodies is ingested through the foods we eat while the other 50% is made in the liver, kidney, and pancreas. Roughly one-third is in its free form as creatine, while the remainder is bound to phosphate and called creatine phosphate or phosphocreatine. During high-intensity, short-duration exercise, such as lifting weights or sprinting, phosphocreatine is broken down into creatine and phosphate. The energy released in this process is used to regenerate ATP, a major source of energy within the human body that drives a number of biological processes including muscle contraction and protein production.
Creatine supplements have gained much popularity in recent years, particularly among body builders and competitive athletes. The attraction of creatine, again, is that it may enhance athletic performance, particularly during high-intensity, short-duration sports (like high jumping and weight lifting).
