Frequent night waking is often linked to low magnesium and stress; magnesium glycinate and glycine support deeper, less broken sleep.

Magnesium calms the nervous system and supports the GABA pathway that keeps you asleep, and many people who wake repeatedly are low in it. Glycine improves sleep quality, and an evening of high cortisol from stress is a common non-nutritional cause of 3am waking that adaptogens like ashwagandha can help blunt over time.
