🌙 How Magnesium Supports Sleep (Backed by Science)

1. Regulates Melatonin Production

Magnesium helps activate melatonin, the hormone responsible for your sleep-wake cycle.

2. Calms the Nervous System

It binds to GABA receptors in the brain—promoting relaxation and reducing brain activity.

3. Reduces Cortisol (Stress Hormone)

Chronic stress can increase cortisol and disrupt sleep. Magnesium helps balance this response.

4. Improves Sleep Quality in Older Adults

One clinical study found that magnesium supplementation significantly improved sleep time, sleep efficiency, and reduced early morning waking in elderly individuals.
