Creatine is produced naturally by the body and helps to supply energy to muscle cells and thus to improve muscles’ performance during exercise. It should allow you to train at higher levels for certain sports and gain muscle. Besides, Creatine plays an essential role in the nervous system, where it provides the energy that keeps us thinking as well as to overcome brain damage because of trauma or disease. Unlike drugs or steroids, Creatine is 100% natural and occurs naturally in many foods.
