Nature Made Magnesium Oxide 250mg
by Nature Made
"USP Verified magnesium at the lowest price — 250mg magnesium oxide from the #1 pharmacist-recommended brand"
Overview
Nature Made Magnesium Oxide provides 250mg of elemental magnesium from magnesium oxide in a USP Verified tablet. Magnesium oxide has the highest elemental magnesium content per gram of any magnesium form (60% elemental vs 14% for glycinate), making it the most efficient way to deliver magnesium in a single tablet. While absorption is lower than chelated forms (4% vs 30-40% for glycinate), the higher elemental content partially compensates. With 200 tablets for under $12 and USP Verified quality, this is the most affordable quality magnesium available.
