Why Magnesium for Dental

Magnesium plays a supporting role in dental. 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.

What dose to look for

Clinical studies typically use 100–400 mg of magnesium. Common clinical supplemental range; RDA for total intake is 310-420 mg. Products below this range may not deliver meaningful results.

What form to look for

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

Magnesium has strong clinical evidence for dental benefits. Meta-analyses confirm benefits for blood pressure, sleep, and glucose; ~50% of adults may be subclinically deficient Learn more
