Glycine is an amino acid, which means the body can make it on its own. It is also consumed in the diet, primarily through meat and fish. Glycine is a building block for making proteins in the body, and it also plays a role in transmitting chemical signals that control important functions like memory and learning.
Glycine is the most important amino acid in collagen production, making it an essential component of bones, cartilage, tendons, skin and hair. It is also needed for the production of glutathione – one of the body’s most powerful antioxidants. Glycine promotes relaxation and sound sleep when taken before bed, but doesn’t cause daytime drowsiness. It may also have positive impacts on mood, cognition and mental health.
Glycine is also used as an additive for seasoning and preservation. Widely used in food manufacturers to increase the level of flavor in their products.
