Creatine is available in many forms inluding Creatine Monohydrate, Creatine Ethyl Ester, Creatine Gluconate, Kre-Alkalyn, Tricreatine Orotate and Creatine Nitrate. Creatine powder is the most popular allowing users the ability to add to their protein shake. There are numerous studies backed by anecdotal evidence that support the efficacy of creatine supplementation. For the majority of the population, from the untrained individual to the elite athlete, creatine supplementation increases lean muscle tissue and improves anaerobic and aerobic performance. Creatine is a natural constituent of meat, mainly found in red meat. Supplementation with creatine increases creatine stored within the muscle, allowing further capacity to regenerate ATP. In other words, the creatine enhances the ability of the muscle to maintain power output during brief periods of high-intensity exercise.
