What is Glycine?
Glycine is a non-essential amino acid, meaning the body can produce it on its own. Despite this, it is important to obtain additional glycine from dietary sources to support its various functions in the body. Glycine plays a critical role in the synthesis of proteins, the production of important compounds like creatine and glutathione, and the functioning of the central nervous system.
Benefits of Glycine
Protein Synthesis: Essential for the production and maintenance of proteins in the body.
Antioxidant Production: Involved in the synthesis of glutathione, a powerful antioxidant.
Detoxification: Helps in detoxifying harmful substances in the liver.
Sleep Quality: Supports healthy sleep patterns by calming the nervous system.
Joint and Skin Health: Plays a role in the production of collagen, which is important for skin, joints, and connective tissues.
