YES!! Creatine monohydrate is one of the most highly supported performance enhancing supplements. It works at the cellular level to increase ATP, which is the energy currency of the body that gives your cells fuel to fire. Creatine has been shown to be effective for increasing muscle mass, to enhance performance during high intensity activity, and to improve recovery. Contrary to some old thoughts, creatine has been shown to be very safe to use. Studies show that it is most effective at a dose of 5g and when used before training or competition with some simple sugars to enhance absorption (e.g. mixed in water with some maple syrup or honey or with some fruit juice). Do not use creatine while cutting weight for competition because it has an affinity for water and will cause you to hold onto water while you are trying to shed water. Other than that, the effectiveness and safety of creatine make it a no-brainer to include in your routine to boost performance!
