A survey of 500 registered dietitians has named magnesium glycinate the most important supplement for 2026, citing that 68% of Americans are deficient and the form offers superior absorption and sleep benefits.
Why Glycinate
Unlike magnesium oxide (poorly absorbed) or citrate (causes digestive issues), glycinate is 80% bioavailable and the glycine amino acid provides additional calming effects that improve sleep quality.
Evidence
Clinical trials show magnesium glycinate improves sleep onset time by 17 minutes, reduces muscle cramps 70%, and lowers anxiety scores by 30% in deficient individuals.
- 68% of Americans are magnesium deficient
- 80% bioavailability vs 4% for oxide
- 17 minutes faster sleep onset
- Recommended dose: 200-400mg before bed
