Why This Supplement Works

Glycine is one of the most important inhibitory neurotransmitters in the central nervous system, particularly in the brainstem and spinal cord. By calming an over-stimulated nervous system, glycine promotes deeper sleep and supports a relaxed mood. It also plays a critical role in phase II liver detoxification by increasing the production of glutathione, the body's master antioxidant. As one of three amino acids that form creatine, glycine further supports muscle function, recovery and energy production in muscle and nerve cells.
