What is the Glycine？

Glycine is an amino acid, a building block for protein. It is not considered an "essential amino acid" because the body can make it from other chemicals. A typical diet contains about 2 grams of glycine daily. The primary sources are protein-rich foods including meat, fish, dairy, and legumes.

Glycine is used for treating schizophrenia, stroke, sleep problems, benign prostatic hyperplasia (BPH), metabolic syndrome, and some rare inherited metabolic disorders. It is also used to protect kidneys from the harmful side effects of certain drugs used after organ transplantation as well as the liver from harmful effects of alcohol. Glycine may also be used to reduce the risk of psychosis. Other uses include cancer prevention and memory enhancement.

Some people apply glycine directly to the skin to treat leg ulcers and heal other wounds.
