Glycine doesn’t work like traditional sedatives. Instead, this amino acid triggers a sophisticated thermoregulatory cascade by activating your brain’s circadian clock—the suprachiasmatic nucleus—to lower core body temperature, the same physiological signal that naturally precedes sleep onset.
Research from Stanford University has mapped this mechanism with precision: a 3-gram dose of glycine binds to NMDA receptors and activates peripheral vasodilation, allowing heat loss through the skin. Clinical trials confirm that this temperature-driven pathway reduces sleep-onset latency and improves next-day alertness without the sedative hangover associated with conventional sleep aids.
At approximately 9 cents per dose, glycine represents one of the most cost-effective and mechanism-based approaches to sleep initiation available. Read the full article on GMJ Newsroom.
