This amino acid is also important in the manufacture of hormones responsible for a strong immune system.

Glycine is also an inhibitory neurotransmitter in the central nervous system (especially in the spinal cord, brainstem, and retina of an eye), which makes it important to help prevent epileptic seizures.

Glycine helps in slowing down the degeneration of muscles since it helps to supply extra creatine in the body. It is also found in fairly large amounts in the prostate fluid and may for this reason be important in prostate health.
