The Evidence

What the research says

Evidence strength: Strong general evidence (50% of adults are deficient)

~50%
Of adults are magnesium deficient
275mg
Elemental magnesium per dose
1-4 weeks
To notice sleep improvements

What we know

  • Approximately 50% of the US population does not meet the recommended daily intake
  • Magnesium plays a role in over 300 enzymatic reactions including neurotransmitter function
  • Glycinate form offers superior bioavailability and is gentlest on the stomach
  • Correcting deficiency has been associated with improved sleep quality in clinical studies

What we're still learning

  • Direct cognitive enhancement effects in people who are not deficient
  • Optimal evening dosing timing for sleep benefits
  • Long-term effects on cognitive performance when deficiency is corrected
  • Whether cognitive benefits are primarily mediated through improved sleep

How We Measure It

Your Pith Baseline tracks the domains magnesium targets

⚡
Quick Tap (Processing Speed)
Morning processing speed reflects sleep quality. Better sleep from magnesium should show up in faster, more consistent reaction times.
🧠
Sequence Memory (Working Memory)
Working memory performance is sensitive to sleep quality. Morning assessments may improve as sleep architecture normalizes.

Dosing & Timeline

What to expect

Recommended dose

275mg daily (2 capsules, evening)

Take with water in the evening. The glycinate form is gentle on the stomach and may support relaxation before bed.

When effects emerge

Week 1 Week 4

Sleep quality improvements are often noticed within the first week. Cognitive benefits that follow from better sleep emerge over 2-4 weeks as your body adjusts.

Safety Profile

What you should know

Magnesium glycinate is one of the gentlest forms of magnesium, well-tolerated even at higher doses. The glycinate form specifically avoids the GI discomfort common with oxide or citrate forms.

May interact with certain antibiotics and blood pressure medications. Consult your doctor if you take prescription medication.
