Creatine supplements have been used by bodybuilders and serious athletes to improve performance and muscle growth for many years. Creatine is a natural substance used by skeletal muscles as energy to contract. Since the early 20th century, it has been recognized that supplementing the diet with creatine supplements increases the amount of creatine in the muscles. These supplements dramatically increase creatinine content in the muscles, leading to better muscle growth, reduced muscle breakdown, and increased strength and performance during anaerobic activity due to higher and faster skeletal muscle energy production. There are many forms of creatine as dietary supplements. We start with creatine monohydrate, which is the oldest form of creatine. Through creatine ethyl ester, crealkaline, tricreatine malate and many others. Finishing off with creatine stacks, which are blends of several forms of creatine. All are offered in mixed drink or capsule form. Studies have shown that these supplements, especially for short-term use, can be used safely and effectively as a bodybuilding supplement. Other studies have shown additional benefits for vegetarians, e.g. improved memory and cognitive function.
