Creatine, a food supplement frequently used by professional and amateur athletes, may prevent brain damage following traumatic brain injury, a new study suggests. Scientists at the University of Kentucky, U.S and the College of Medicine Department of Anatomy and Neurobiology in the U.K. demonstrated that brain damage in mice was reduced 21 percent and 36 percent when creatine was administered three and five days before traumatic brain injuries (TBI) respectively. The data also show that in rats fed a diet supplemented with creatine for four weeks before TBI, brain damage was reduced 50 percent when compared to rats fed a regular diet. Creatine is produced naturally in the body in the liver, kidney and pancreas and is used as a way to store energy. The full study was published in the November issue of Annals of Neurology.
