Creatine is a naturally-occurring compound found in the brain and muscle, which plays an important role in the short-term energy system. While we make creatine in the body and also consume through meat and fish, additional intake is required to saturate the creatine stores in the body. That’s where Micronised Creatine Powder from Optimum Nutrition comes in, whether pushing that final rep or sprint, to help take your performance to the next level.
