Magnesium is one of the most popular supplements for improving sleep quality, relaxation, and recovery. But not all magnesium is created equal. With multiple forms — from citrate to glycinate — it can be confusing to know which one is best for a good night’s rest.
In this guide, we’ll break down the most common types of magnesium, their benefits, and which ones work best for sleep.
Why Magnesium Matters for Sleep
Magnesium supports more than 300 processes in the body, including:
-
Regulating melatonin, the sleep hormone.
-
Calming the nervous system by binding to GABA receptors.
-
Relaxing muscles to reduce tension and restlessness.
Deficiency in magnesium has been linked to poor sleep, fatigue, and even higher stress levels.

When it comes to sleep, magnesium glycinate is the clear winner. Its combination of high absorption and calming effects makes it the most effective option for nighttime relaxation.
✨ That’s why we included magnesium glycinate in Moondust by Daily Drips — a nighttime drink mix that blends magnesium with ashwagandha to support restful, deep sleep.
