Creatine
Creatine is a molecule that’s produced in the body from amino acids. It’s primarily made in the liver and to a lesser extent in the kidneys and pancreas.
It stores high-energy phosphate groups in the form of phosphocreatine which are donated to ADP, regenerating it to ATP, the primary energy carrier in the body. This role in energy production is particularly relevant under conditions of high energy demand such as short, intense physical activity.
Creatine is most prevalent in meat and fish, which is why vegans and vegetarians may have even less of it unless they take supplements.
Creatine is a safe and effective supplement.
