What food products contain creatine?
Food sources such as beef, salmon, pork, cod, herring etc. contain creatine in abundance. It is also made naturally from the amino acids L-arginine, L-glycine and L-methionine that are available in animal protein. Insulin is required to help creatine enter the muscle tissues. Thus, consumption of carbohydrates with creatine enhances its overall content in the muscle cells.
