What is Creatine and How Does It Work?
Creatine phosphate (CrP) is a compound made of three amino acids: arginine, glycine, and methionine. The body produces creatine naturally in the liver, kidneys, and pancreas, with about 95% of it found in skeletal muscle. “Through diet, creatine is found primarily in red meat and seafood, however, to get an extra creatine boost, a creatine powder or pill supplement can help,” says personal trainer and strength coach Will Duru.
Creatine supplies energy to muscles through the phosphocreatine system. “Creatine helps in the production of ATP (adenosine triphosphate)—the compound that provides energy to bodily processes such as muscle contraction,” nutritionist Rob Hobson says. “Creatine can help with the production of ATP during maximum-effort exercises, such as sprints or intense muscular effort lasting between five and 10 seconds. It can also help recovery between exercise bouts.”
