Why Magnesium Matters
Magnesium is involved in over 300 biochemical reactions in your body. Despite its importance, studies suggest that up to 50% of Americans are deficient in this essential mineral.
Magnesium and Sleep
Magnesium plays a crucial role in sleep quality. It helps regulate melatonin, the sleep hormone, and activates the parasympathetic nervous system — your body's "rest and digest" mode.
Research shows that magnesium supplementation can:
- Reduce the time it takes to fall asleep
- Improve sleep quality and duration
- Reduce nighttime muscle cramps
- Decrease restless leg syndrome symptoms
Magnesium and Muscle Recovery
For athletes and active individuals, magnesium is essential for:
- Muscle relaxation after exercise
- Protein synthesis for muscle repair
- Reducing inflammation and soreness
- Preventing exercise-induced cramps
Types of Magnesium
Different forms of magnesium have different benefits:
- Magnesium glycinate: Best for sleep and anxiety. Gentle on stomach.
- Magnesium citrate: Good for general supplementation. May have laxative effect.
- Magnesium threonate: Best for brain health and cognitive function.
- Magnesium taurate: Best for heart health and blood pressure.
Recommended Dosage
Adults need 310-420mg of magnesium daily. For supplementation:
- For sleep: 200-400mg before bed
- For recovery: 200-400mg after exercise
- For general health: 200-400mg daily with food
