What is it?
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 and regenerates 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 intense physical or mental activity.
What does it do?
Creatine can help with exercise performance by rapidly producing energy during intense activity. The primary benefit of creatine is an improvement in strength and power output during resistance exercise. When used in conjunction with resistance exercise, creatine may modestly increase lean mass.
