Estella Dotson Answers to Important Questions Concerning Creatine Monohydrate .
Creatine is a metabolite that is produced naturally by the human body.
It is found mainly in the red muscle tissue, but it is also present in the heart and brain. Normally, creatine is acquired through regular dietary intake of products such as meat and fish, which are high in protein. However, when dietary intake is low creatine can be produced from natural amino acids such as glycine, arginine, and methionine in the liver, kidneys, and pancreas. Creatine functions to increase the availability of cellular ATP, adenosine triphosphate. This is followed by the maintenance phase, which sustains the desired high levels of creatine in the body.
