Glutamate and the Human Body

Glutamate is produced in the human body and plays an essential role in metabolism. Almost two kilograms (about four pounds) of naturally occurring glutamate are found in muscles, in the brain, in kidneys, in the liver and in other organs and tissues. In addition, glutamate is found in abundance in mothers’ milk, at levels about ten times that found in cows’ milk.
