Glycine is a non-essential amino acid, and its principal function is as a precursor to proteins.
Glycine converts glucose to energy, helps to regulate blood sugar levels, assists the digestive process, and is an inhibitory neurotransmitter in the central nervous system.
Glycine helps the body to repair damage tissues, protects the skin from becoming slack from UV rays and from oxidation and free radical damage. Glycine has a calming effect and is sometimes used to treat manic depressive and aggressive individuals. Glycine produces Glucagon, which mobilizes Glycogen. It also inhibits sugar cravings.
Some studies carried out have shown that Glycine may help in the treatment of schizophrenia, and have also shown that it may provide protection from some types of cancer.
