A bioavailable, gentle form of magnesium often used for sleep and calm.
How it works
Magnesium supports GABA receptor activity and muscle relaxation; the glycinate form is well absorbed and is gentle on the gut.
Evidence
Several small randomized trials suggest magnesium supplementation may modestly improve subjective sleep measures in adults with low intake or in older adults. Effect sizes are modest and replication is limited.
Studies
Abbasi et al., J Res Med Sci, 2012
Improved subjective sleep in older adults at ~500 mg elemental magnesium per day for 8 weeks.
