What is creatine?
Creatine is a naturally occurring substance in muscle cells. It can help your muscles generate energy during weight lifting or high-intensity exercise

Taking creatine as a supplement is very popular among athletes and bodybuilders to increase muscle, strength and performance

Chemically, it has many similarities with amino acids. Your body can produce it from the amino acids glycine and arginine

There are several factors that affect your body's creatine reserve, including meat intake, exercise, muscle mass, and hormone levels such as testosterone and IGF-1

About 95% of body creatine is stored in muscle in the form of creatine phosphate. The other 5% is in your brain, kidney and liver

When you replenish, you will increase the storage of creatine phosphate. This is a form of energy storage in cells, because it can help your body produce more high-energy molecules called ATP

ATP is often referred to as the energy currency of the body. When you have more ATP, your body will perform better when exercising

Creatine also alters several cellular processes that lead to increased muscle mass, strength, and recovery
