Glycine
The simplest amino acid, serving as an inhibitory neurotransmitter and a building block for collagen, glutathione, and creatine. Promotes sleep quality by lowering core body temperature.
What it’s good for
InsomniaStrong
Glycine acts on NMDA receptors in the suprachiasmatic nucleus to lower core body temperature, a key signal for sleep initiation. It also increases serotonin levels in the prefrontal cortex and enhances slow-wave sleep quality.
Dose: 3000 mg
Poor Sleep QualityStrong
Glycine enhances slow-wave (deep) sleep by lowering core body temperature through peripheral vasodilation. It also modulates NMDA receptors and increases serotonin in sleep-regulating brain regions, improving overall sleep architecture.
Dose: 3000 mg
