Why glycine is good for you

Glycine is a sweet-tasting, non-essential amino acid that can be produced from serine and threonine, so dietary intake is not essential.

Glycine is required to build protein in the body. It is required for the synthesis of nucleic acids, the construction of RNA as well as DNA and synthesis of bile acids and other amino acids in the body. Glycine is also found to be useful in assisting with the absorption of calcium in the body. It helps in retarding degeneration of muscles as it helps to supply extra creatine in the body. Glycine is important in the body's manufacture of hormones responsible for a strong immune system.
