Glycine is a simple amino acid with powerful effects on sleep quality, collagen synthesis, and longevity. Taking it before bed improves deep sleep, and it may mimic some benefits of methionine restriction.
Glycine lowers core body temperature, promoting sleep onset. It acts on NMDA receptors for cognitive effects and serves as a collagen precursor. It may also mimic methionine restriction for longevity benefits.
