Magnesium: The Ultimate Guide — Key Takeaways

Take 200–400 mg daily of magnesium glycinate or malate (starting at 100 mg), away from calcium and fiber, to address deficiency affecting 75% of people and linked to fatigue, anxiety, poor sleep, and insulin resistance.
Key takeaways
High-absorption magnesium forms + transdermal combo maximizes status
High-absorption magnesium forms + transdermal combo maximizes status
- Glycinate, taurate, malate, gluconate absorb far better than oxide (~4% absorbed) or citrate; start at 100mg elemental, scale up.
- 20-min daily MgCl2 foot bath shown to raise magnesium status; take oral dose away from calcium and high-fiber foods.
382mg MgCl2 cuts blood sugar 25%, triglycerides 50%
382mg MgCl2 cuts blood sugar 25%, triglycerides 50%
- 382 mg magnesium as MgCl2 reduced blood sugar by 25%, triglycerides by half, plus lowered BP and insulin.
- Mechanism: magnesium facilitates glucose metabolism through multiple pathways; dose is low-cost and achievable.
ADHD drugs deplete magnesium — and 95% of ADHD patients are already deficient
ADHD drugs deplete magnesium — and 95% of ADHD patients are already deficient
- Up to 95% of ADHD patients are magnesium deficient; standard ADHD medications actively worsen this depletion.
- 200 mg/day improved inattention by 75%+ and hyperactivity by nearly 90% in trials — suggesting deficiency is a driver.
