Creatine is among the most well-researched and effective supplements. It can help with exercise performance by rapidly producing energy during intense activity.
Creatine may also provide cognitive benefits but more research is needed in that area.
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
is 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 intense physical or mental activity.
The primary benefit of creatine is an improvement in strength and power output during resistance exercise.
