Not all magnesium supplements are created equal. With so many forms—like citrate, oxide, malate, and glycinate—it can be overwhelming to choose. So what makes magnesium glycinate different?
🔍 Quick Comparison Chart
| Type | Absorption | Main Benefit | Common Side Effects |
|---|---|---|---|
| Glycinate | High | Calming, sleep, anxiety relief | Very few |
| Citrate | Moderate–High | Digestion, constipation relief | May cause loose stools |
| Oxide | Low | Short-term laxative use | Often causes stomach upset |
| Malate | Moderate | Muscle recovery, energy | Rare |
| Threonate | High (brain) | Cognitive function | Expensive, limited studies |
💡 Why Glycinate Stands Out
- Highly absorbable: Chelated with glycine, a calming amino acid
- Gentle on digestion: Unlike citrate or oxide, it rarely causes GI issues
- Great for stress/sleep: Glycine enhances calming neurotransmitter activity
🧪 Backed by Research
Studies have shown magnesium glycinate to be one of the best-tolerated forms, with a strong safety profile and good bioavailability.[1]

✅ Best Form For You?
- Choose glycinate if you want sleep, anxiety, or muscle recovery support
- Try citrate if you need occasional constipation relief
- Look into threonate if cognitive support is your priority (with a higher budget)
Bottom line: Magnesium glycinate is one of the best all-around choices for daily use. It’s gentle, effective, and well-absorbed—ideal for sleep, stress, and nervous system support.
