Overview
Glycine acts as an inhibitory neurotransmitter and, crucially, promotes vasodilation (widening of blood vessels) at the extremities. This helps dump core body heat, lowering temperature to facilitate deep sleep.

Lowers body temperature.
Taken before bed (3-5g), Glycine mimics the physiological temperature drop of sleep onset by promoting vasodilation (blood flow) to the hands and feet.
This dumping of heat from the core is the biological signal for the brain to enter Deep Sleep (NREM3), leading to better physical restoration and subjective sleep quality.
