What Does Glycine Do?

Glycine plays a part in normal neurotransmission and supports basic protein synthesis, contributing to cellular metabolism and overall bodily body function.

Its involvement in these normal processes is laid out in general nutrient guidance and fits with widely recognised roles of amino acids in the body.

This supplement is not meant to diagnose, treat, cure, or prevent any disease.
