  • Applications

    Creatine (57-00-1) is widely used as a dietary supplement in sports nutrition to support energy metabolism and high-intensity performance; in cosmetics and personal care it is explored as a cosmetic ingredient with potential moisturizing/conditioning and antioxidant-related benefits in certain formulations; in pharmaceutical and biochemical research it serves as a precursor or reference compound for the synthesis and study of guanidino compounds and energy pathways; in animal nutrition it is evaluated as a feed additive to provide energy and support muscle development in some species; in industrial manufacturing it can function as a building block or intermediate for the synthesis of related guanidino compounds and derivatives. Subject to local regulations and formulation limits.
