Creatine monohydrate is the most common type of creatine, in supplements, as well as the most researched. Lots of scientific evidence suggest that creatine monohydrate is a substance that works and many people that use it for the past 40 years, confirm those claims with the results they have seen in their bodies.
Creatine is essentially an amine (literally a nitrogenous amino acid) that is naturally produced in our bodies by the amino acids: glycine, methionine and arginine (95% of our body’s creatine is stored in muscle cells). Moreover, creatine is also present in foods such as meat & seafood.
What creatine as a nutrient actually does, is to give your muscles more energy, during exercise, which increases the amount of work muscle cells can do. That means that your muscles are able to perform better and gradually are becoming stronger. This is a key factor in long-term muscle growth.
