Magnesium for Sleep: Does It Work?

Short answer: Yes, magnesium supports sleep by calming the nervous system and relaxing muscles, and many people are mildly deficient. The best-absorbed, gentlest form for sleep is magnesium glycinate, taken in the evening.

How magnesium helps sleep

Magnesium supports GABA activity (your 'calm down' system) and helps regulate the stress response. Low levels are linked to tension, restlessness and poor sleep.

The best form for sleep

• Magnesium glycinate: calming and easy on the stomach (best for sleep).
• Magnesium citrate: well absorbed but can be laxative.
• Magnesium oxide: poorly absorbed; not ideal.

Femme Flourish uses magnesium glycinate; for a dedicated bedtime calm, pair with our Sleep Tincture.
