Best Magnesium for Sleep (2026): Glycinate vs Citrate + Picks
Updated 2026 • Expert guide with product picks • Save with KHQ339
✨ Quick Answer
The best magnesium for sleep is magnesium glycinate (200-400mg before bed). Glycine enhances sleep quality while magnesium relaxes muscles. Avoid citrate—it's better for constipation, not sleep. Save with KHQ339 at iHerb.
Why Trust This Guide
Different magnesium forms have vastly different absorption rates and effects. We break down which type works best for sleep vs. other health goals.
- Magnesium glycinate is best for sleep because glycine itself has calming, sleep-promoting effects.
- Magnesium citrate has a laxative effect—great for constipation, not ideal for sleep.
- Take magnesium 1-2 hours before bed for best sleep effects. It takes time to relax the nervous system.

What to Look For
- Glycinate or bisglycinate form: Best absorption and sleep benefits due to glycine.
- 200-400mg elemental magnesium: Check 'elemental' amount, not total compound weight.
- No magnesium oxide: Poorly absorbed and causes digestive issues.
- Third-party tested: Heavy metal contamination is a concern with magnesium.
- Capsules over tablets: Better absorption than compressed tablets.

Frequently Asked Questions
What type of magnesium is best for sleep?
Magnesium glycinate is considered best for sleep because the glycine amino acid has its own calming effects. Magnesium threonate (Magtein) is also good and may cross the blood-brain barrier more effectively.
How much magnesium should I take for sleep?
Start with 200mg of elemental magnesium glycinate 1-2 hours before bed. You can increase to 400mg if needed. Higher doses may cause loose stools.
Can I take magnesium every night?
Yes, magnesium is safe for daily use and many people are deficient. It may take 1-2 weeks of consistent use to notice sleep improvements.
