The Active Ingredient Is: Glycine (Free-Form)

Glycine is a non essential amino acid that occurs naturally in proteins and tissues and can be consumed as a pure free-form supplement.

This product contains pharmaceutical-grade glycine in a free-form powder, produced in allergen controlled, vegan, non-GMO facilities with stringent quality assurance to support purity and potency.

What Does Glycine Do?

Glycine participates in normal nervous system function and supports sleep quality by acting as a calming neurotransmitter, as described in scientific research on sleep and metabolic health.

Research notes that glycine may contribute to antioxidant defence and energy metabolism, with evidence suggesting improved subjective sleep quality in adults. NHS and EFSA guidance emphasises its role in normal physiological processes.
