What Is Creatine?
Creatine is an organic compound made from three amino acids: arginine, glycine, and methionine. While the body naturally produces creatine, people can also take in creatine through the diet (from meat) and through supplements in the form of creatine monohydrate.
Creatine plays a role in supplying energy to the cells, especially the muscle cells, during anaerobic activity. During an aerobic exercise such as resistance training, after ATP is quickly used up for energy, the body begins to break down creatine to make more ATP. This is why creatine is a favorite supplement ingredient among sports performance consumers, as they seek ways to increase their exercise capacity to make greater gains in muscle mass and strength.
Populations Who Might Benefit from Creatine
Sports Performance & Energy Consumers
Sports performance consumers are the most likely to use creatine supplements. Nearly 70% of creatine users exercise seven or more hours per week, and they’re much more likely to do bodybuilding or competitive weightlifting than the general population (28% vs. 14%).1 They’re also more likely to participate in team sports such as football, basketball, hockey, and soccer (36% vs. 21%) and combat sports like martial arts, boxing, and wrestling (25% vs. 15%).2 While improving performance is the main goal, some also use creatine for recovery benefits.
