The research behind magnesium
What the sleep
research found.
A placebo-controlled trial of magnesium bisglycinate found an improvement in self-reported sleep scores after four weeks. The effect was small.
- adults in a randomized trial
- 155
- Schuster et al., 2025
- days in the randomized trial
- 28
- Schuster et al., 2025
- elemental magnesium daily in the trial
- 250 mg
- Schuster et al., 2025
- adults in a separate observational study
- 3,964
- Zhang et al., 2022
The trial used 250 mg of magnesium daily; HAVN1 provides 275 mg per serving. A separate observational study linked higher magnesium intake with lower odds of short sleep, but it cannot show that magnesium caused the difference. Neither study tested HAVN1.
