Relationship between short-term self-reported dietary magnesium intake and whole blood ionized magnesium (iMg²⁺) or serum magnesium (s-Mg) concentrations.

ABSTRACT:

Objective

Since we and others have shown that supplemental magnesium raises whole blood ionized magnesium (iMg²⁺) we investigated the relationships between self-reported dietary magnesium intake and concentrations of whole blood iMg²⁺ and serum magnesium (s-Mg).

Methods

We obtained whole blood iMg²⁺ concentrations, as well as s-Mg concentrations, from a pilot, three-arm, randomized, controlled, crossover bioavailability study of magnesium supplements (n = 23; 105 measures). Dietary magnesium intake was assessed using three-day food records and the Nutrition Data System for Research (NDSR, University of Minnesota, MN, USA). Whole blood iMg²⁺ was measured with an electrode analyser (NOVA Biochemical, Waltham, MA, USA), whereas
