Creatine is involved in the production of energy in the body (as ATP). ATP is used as an energy sources for muscles during high-intensity, low-duration activities such as sprinting and weight lifting. Although it’s naturally found in red meat and fish, most of it is destroyed in cooking, so many look to creatine supplements. There has been a lot of research into the athletic performance of creatine, and results suggest that creatine supplements improve performance in high-intensity, low-duration activities and also decrease muscle fatigue and reduce lactic acid.
