Glycine plays many roles in the body including acting as a neurotransmitter in the brain, where it supports healthy nerve impulses. It is also important for supporting healthy sleep patterns. Oxidative Stress Glycine is one of the amino acids essential to the body’s synthesis of the antioxidant glutathione. The glutathione system processes toxic substances produced in our diet such as alcohol, air pollution and other toxic chemicals that we ingest. Cells produce glutathione in order to fight free radicals that can cause oxidative stress and damage cells, proteins, and DNA. As we age, the body's natural ability to synthesize glutathione declines, however this can be supported through supplementation with glycine.
