Creatine Ethyl Ester, commonly abbreviated to CEE, is a nutritional supplement that is deemed to aid athletes, body builders in particular, with development of muscle tissues and in improving the overall athletic performance. It is a form of creatine that is immediately formed back to regular creatine in the human body. The ethyl ester variant has proven to have a faster absorption rate as well as a longer durability within the human body, the so called half life, when compared with the regular creatine monohydrate. Due to recent disputes in the efficacy of CEE, other forms of creatine supplements have been preferred, such as Di-Creatine Malate and Tri-Creatine Malate. Creatine is in every case the compound supplemented, which is proven to boost the lean muscle mass and improve muscle strength as well as the athletic performance.
