Glycine is the smallest and simplest amino acid, making it versatile for a wide range of functions. Glycine is necessary for the production of glutathione, DNA, creatine, bile, hemoglobin and most proteins. It also helps stimulate glycogen storage, thereby making glucose readily available for energy production. Glycine also functions as a calming neurotransmitter in the brain, where it facilitates nerve impulses and is important for maintaining healthy sleep.
