Glycine is precursor for a variety of important metabolites such as glutathione, porphyrins, purines, haem, and creatine. Glycine acts as neurotransmitter in central nervous system and it has many roles such as antioxidant, anti-inflammatory, cryoprotective, and immunomodulatory in peripheral and nervous tissues.

 

Glycine stimulates the production of serotonin , the “feel-good” hormone that helps elevate mood, improve sleep, and enhances memory and thinking.
