Up to 75% fall short on magnesium. Here’s how to fix it smartly.

Magnesium: Sleep, Stress, and Performance

Why it matters, signs you’re low, and which forms to choose.

Why It Matters

  • ATP energy production.
  • Muscle relaxation & nerve calm.
  • Sleep quality & stress resilience.
  • Glucose control & bone health.

Low-Mag Signs

Cramps/twitches, restless sleep, anxiety/irritability, headaches, constipation, fatigue.

Best Forms

  • Glycinate — calming, gentle, great for sleep.
  • Threonate — brain-targeted, cognitive support.
  • Citrate — well absorbed; higher doses can loosen stools.
  • Malate — energy support, well-tolerated.

Oxide is poorly absorbed (mostly a laxative).

Dosing & Timing

Typical 200–400 mg elemental/day. For sleep: 30–60 min before bed. Split doses (<200 mg each) may absorb better.
