The Active Ingredient Is: Glycine

Glycine is a simple amino acid used as a common building block in the body and functions in its free form when taken as a supplement.

This product offers pure glycine in capsule form for oral use, supporting its role as an endogenous amino acid involved in normal bodily processes.

What Does Glycine Do?

Dr. Yamadera from Kyoto University found that glycine ingestion improves subjective sleep quality and reduces time to sleep onset, supporting normal sleep patterns.

Glycine plays a role in glutathione biosynthesis, contributing to the body's antioxidant capacity, and it is a structural amino acid that participates in collagen formation to support connective tissue integrity.

This supplement isn't meant to diagnose, treat, cure, or prevent any disease.
