Doctor's Best uses TRAACS magnesium bisglycinate chelate (the gold-standard form for absorption without the diarrhea that magnesium oxide causes). 200mg per 2-tablet dose. 240ct = 4 months at 2/day. The magnesium that clinicians actually recommend for sleep and muscle relaxation.

Frequently asked questions
Doctor's Best vs Thorne magnesium glycinate?
Doctor's Best is a third of the price with identical TRAACS chelate form. Thorne has better lab certifications for medical professionals but for consumer sleep use, Doctor's Best is the value pick.
How long until magnesium glycinate works for sleep?
Typically 1-2 weeks of consistent use. Unlike melatonin (immediate effect), magnesium works by correcting deficiency + supporting GABA. Start dosing 1-2 weeks before you expect results.
Is 200mg the right dose?
Standard adult dose is 200-400mg. Start at 200mg (one 2-tablet serving); increase to 400mg if needed. Higher doses require splitting (morning + evening) to avoid absorption saturation.
Magnesium glycinate vs magnesium citrate for sleep?
Glycinate is better for sleep — the glycine amino acid itself has sedative properties. Citrate is better for constipation. Different tools.
