Nature?sField Creatine Monohydrate powder is a dietary supplement made up of one creatine molecule (a type of amino acid which is the building block of protein) combined with one molecule of water. The human body already produces creatine on its own which helps with a steady supply of energy. If you work out a lot, you can often find your energy levels depleted. Therefore supplementing with creatine monohydrate boosts the amount of creatine in your body primarily used for muscle function and fast recovery during exercise.
