Glycine is an amino acid found in many protein food sources that helps support normal detoxification by serving as a precursor to Glutathione, a powerful intracellular antioxidant which is involved in both Phase I and II of liver detoxification.* Glycine also helps maintain a healthy nervous system and is used to alleviate mild memory changes associated with aging.* It activates many receptors in the brain which promote neural development, learning, and cognition.* Glycine is a major inhibitory neurotransmitter which supports relaxation and healthy stress management.* Clinical research suggests that taking glycine before bedtime may promote sleep quality and modestly reduce feelings of fatigue.* It should not be taken with clozapine.
