Why magnesium matters

Magnesium supports GABA signaling, muscle relaxation, and parasympathetic activation — all relevant to sleep onset and depth.

Form comparison

Glycinate: best sleep evidence, minimal GI effects. Threonate: brain penetration, modest data. Citrate: cheap but laxative effect at sleep doses.

Frequently asked questions

Best dose for sleep?
200-400 mg of magnesium glycinate 30-60 minutes before bed.
Can I overdose?
Above 600 mg daily can cause GI distress. Kidney patients should consult a physician.
