What Makes Magnesium Glycinate Good for Sleep?
Magnesium glycinate is one of the most sleep-friendly forms of magnesium because it’s bound to glycine—an amino acid with calming effects on the brain. Unlike magnesium citrate or oxide, glycinate is less likely to cause diarrhea or stomach upset. According to many Reddit users, it helps:
- Reduce nighttime anxiety
- Support melatonin production
- Prevent nighttime waking
- Alleviate muscle tension and restless legs
How Redditors Take It
- Common dose: 200–400mg elemental magnesium, 30–60 minutes before bed
- Best time: With or after dinner, or just before winding down
- Stacking: Some combine it with L-theanine or melatonin for extra effect
Final Thoughts
If you’re looking for a reliable magnesium glycinate supplement for sleep, Reddit users overwhelmingly suggest starting with Doctor’s Best, KAL, or Pure Encapsulations—depending on your budget and sensitivity. If you prefer powders, NOW Foods and Lucid-Mg are popular choices.
As always, check with your healthcare provider before starting a new supplement, especially if you’re on medication or managing a health condition.
