Glycine is the simplest of the 20 different amino acids used as building blocks to make proteins for your body. It works in concert with glutamine, a substance that plays a major role in brain function. Glycine has shown some promise as an aid in the treatment of schizophrenia and may have other uses related to the brain as well, such as enhancing mental function.
Your body is able to make glycine using another amino acid, serine. Because you can manufacture glycine, you do not really have to consume any, so it is called a "nonessential amino acid." Most of us get about 2 g of glycine a day from the foods we regularly eat anyway. This dietary glycine comes mostly from high-protein foods like meat, fish, dairy products, and legumes. For treating certain disease conditions, however, much larger amounts than are normally consumed have been advocated; such high doses can only be obtained by taking supplements.
