Glycine is a non-essential amino acid with remarkably precise effects on sleep architecture. Unlike sedatives, it does not knock you out — it prepares the physiological ground. Its first mechanism: by activating glycinergic receptors in the skin, it triggers peripheral vasodilation that lowers core body temperature by 0.3 to 0.5°C. This cooling is the natural biological signal that marks the entry into deep sleep. Result: easier sleep onset and increased slow-wave deep sleep phases (delta waves). Second mechanism: as a co-agonist of NMDA receptors, glycine modulates waking circuit activity, reinforcing the overall architecture of restorative sleep.
Beyond sleep, glycine is one of the three constituent amino acids of glutathione (with cysteine and glutamic acid) — the human body's primary intracellular antioxidant. Regular supplementation maintains glutathione reserves, particularly valuable after age 30 when endogenous synthesis declines. It is also the structural backbone of collagen: every third amino acid in the triple helix is a glycine (Gly-X-Y motif). Three grams per night supply the raw material for continuous collagen synthesis during your sleep.
Our Glycine is produced by enzymatic fermentation (non-GMO), certified purity ≥99.5%. Naturally sweet — the etymology comes from the Greek glykys — it dissolves in seconds in water, herbal tea, or warm milk. No artificial flavors, no sweeteners, no excipients. The 1 g dosing spoon is included: 3 level scoops = 3 g, the reference protocol from clinical studies. One clean ritual, one simple formula.
Glycine is fundamentally different from melatonin: it is not a hormone and creates no dependency or rebound effect. It does not dictate when you fall asleep — it deepens quality once you are lying down. Usable every evening without interruption. For a complete night stack: Glycine + Magnesium Bisglycinate (muscle relaxation and synergistic NMDA modulation) + Unwind to calm the mind. These three products form Nootropic.ma's reference night protocol.
