MRI® Performance Creatine Monohydrate is 100% pure, flavorless, micronized creatine monohydrate with no fillers or additives. Creatine is a naturally occuring molecule in the body that plays a key role in explosive energy metabolism. It helps drive periods of shortburst power output; the first few reps in a set or the explosive drive from the starting blocks. During exercise, intramuscular stores of creatine reload ATP molecules, the "energy machines of muscle," for fast between - set recovery. Unfortunately, the creatine produced by the body is available only in limited supply. Supplementing with MRI® Performance Creatine Monohydrate helps supersaturate muscles with rapid-fueling creatine, driving improved muscle power output, explosive strength, and rapid intra - workout recovery.
