Creatine supplements have been used by body-builders and serious athletes to boost performance and muscle growth for many years. Creatine is a natural substance used by skeletal muscles as energy for contracting. Since the early 1900’s it has been recognized that supplementing your diet with creatine supplements raises the amount of creatine found in the muscles. Creatine supplements dramatically increase the level of creatine in the muscles, leading to better muscle growth, decreased muscle deterioration, and increased power and performance for anaerobic activity due to higher and faster energy creation in the skeletal muscle. There are many forms of creatine available as supplements. Begining with creatine monohydrate the oldest form of kreatine. Through creatine ethylester, kre-allkalyn, tricreatine malate, and many others. Finishing with creatine stacks which are mixtures of many forms of creatine. All are offered in drink mix form or capsule form. Studies have shown that creatine, particularly in short-term use, can be safely and effectively used as a body-building supplement. Other studies have shown added benefits to vegetarians, such as heightened memory and cognitive function.
