Magnesium Glycinate
for Insomnia
The glycinate form of magnesium is well absorbed and has a calming effect on the nervous system, making it a popular pre-sleep supplement. Take 200-400 mg in the hour before bed, ideally with a small snack. It is gentler on digestion than magnesium oxide and less likely to cause loose stools.
How it works
Modulates NMDA receptor activity and GABA-A receptor function. Deficiency is associated with sleep disruption and nocturnal awakenings.
What to watch for
Take 1–2 hours before bed. 400mg glycinate form is better tolerated than oxide. Loose stools possible at high doses.
