What is German Creatine? Weightlifters around the world have used Creatine for decades to support demanding workouts. Creatine (creatine monohydrate) is a substance naturally occurring in the body and also found in animal foods like meat, fish and poultry. However, an additional source is often needed to supplement a more demanding weightlifting regimen. Bodybuilders, fighters and athletes from all over have chosen Fitness Lab's German Creatine because it is greater than your average supplement.
