Taking 3 grams of glycine before bed doesn't seem to change the overall structure of sleep stages, according to sleep monitoring
Scientific Claim
Glycine ingestion (3 g) before bedtime is associated with no significant changes in sleep architecture in individuals with chronic sleep dissatisfaction
Source Excerpt
“Glycine improved subjective sleep quality and sleep efficacy (sleep time/in-bed time), and shortened PSG latency both to sleep onset and to slow wave sleep without changes in the sleep architecture.”
