Glycine (as in dietary supplement)

Glycine is an amino acid, a building block of proteins found naturally in the body. When taken as a dietary supplement, glycine may support muscle health, improve sleep quality, and promote joint and skin health. It acts as a neurotransmitter in the brain, helping to calm the nervous system and aid relaxation. Glycine is generally considered safe and is found in protein-rich foods like meat, fish, and legumes. Supplementing with glycine is often used for its potential benefits in enhancing overall well-being, particularly for those seeking support for sleep and mental clarity.
