Glycine is defined as a non-essential amino acid. Glycine can help remove toxic substances like lactic acid from the body, and it may also increase the use and availability of growth hormone.
It has been proven to promote the release of growth hormone and to support cell volumizing as well as slowing down the breakdown of muscle tissue. It is also helpful in healing damaged muscles or in simply rebuilding muscle tissue in athletes who participate in strenuous workouts.
The body uses glycine to make proteins. Glycine is also involved in the transmission of chemical signals in the brain, so there is interest in trying it for schizophrenia and improving memory.
