Summary
A 90-day randomized controlled study found that daily magnesium supplementation (400mg) improved HRV parameters and reduced stress markers in adults experiencing mental and physical stress. Results need replication.
Methods
Randomized controlled trial, 100 participants, 90-day intervention
Key Findings
- pNN50 (parasympathetic indicator) significantly increased
- Stress index decreased with supplementation
- 400mg daily magnesium showed benefits in stressed individuals
- Effects emerged over weeks of consistent supplementation
Limitations
Single study, specific population already experiencing stress, needs replication in broader populations
What This Means for You
Magnesium supplementation (400mg daily) may help improve HRV in people experiencing chronic stress, but evidence is limited to one study. Most people get adequate magnesium from diet. Consider testing levels before supplementing.
