Clinical dose: 100–400 mg
Magnesium and general health
Magnesium plays a supporting role in general health. Cofactor in over 300 enzymatic reactions including energy production, protein synthesis, and nervous system regulation. Magnesium glycinate is preferred for calm and sleep support with minimal GI effects, threonate (Magtein) crosses the blood-brain barrier for cognitive benefits, and citrate has a mild laxative effect useful for constipation.
Effective dosing
Most evidence supports 100–400 mg of magnesium daily. Common clinical supplemental range; RDA for total intake is 310-420 mg. Products below this range may not deliver meaningful results.
Form and bioavailability
Avoid magnesium oxide — low absorption (~4%). Avoid magnesium stearate — filler, not a bioavailable form. Look for magnesium glycinate or magnesium citrate for better absorption.
What the research says
The clinical evidence for magnesium in general health is strong. Meta-analyses confirm benefits for blood pressure, sleep, and glucose; ~50% of adults may be subclinically deficient Learn more
