This is 100% pure white crystalline creatine. A scientifically proven athletic supplement that clearly improves exercise capacity. Studies have shown that it can enhance the quality of training, resulting in a 5 to 15 percent gain in strength and performance(1). So, what is creatine? Our bodies naturally make the compound, which is used to supply energy to our muscles. It is produced in the liver, pancreas, and kidneys, and is transported to the body's muscles through the bloodstream. Once it reaches the muscles, it is converted into phosphocreatine (creatine phosphate). This high-powered metabolite is used to regenerate the muscles' ultimate energy source, ATP (adenosine triphosphate).
