Creatine is an organic compound obtained through diet mostly from meat and fish. In the human body, creatine combines with inorganic phosphate and forms Creatine Phosphate which is a high-energy compound. Creatine supplementation is popular in body builders, or people who are wanting to increase their muscle mass as well as to increase their overall performance as an athlete. The most popular form of creatine supplements is Creatine Monohydrate because it can result in a 20% increase in the amount of creatine stored in muscles. Increased creatine storage is presumed to enable individuals to train more intensely, causing him/her to build more muscle mass and enhances their performance in a shorter amount of time. There are two phases within creatine supplementation: the loading phase and the maintenance phase. According to current data, there have been no side effects other then stomach cramping which have only been in rare cases. Supplementation is most beneficial during exercise training (anaerobic) and does not benefit athletes competing in aerobic endurance events.
