E: 91 The Great Magnesium Debate

Send Audrey a Text to get your question answered on the show There is a lot of confusion in the magnesium space. Which form is better? What is all of this elemental magnesium talk? Here’s the scoop, claims that magnesium oxide is better are based on misinterpreted comparisons, typically magnesium oxide vs magnesium citrate, and/or on something called elemental magnesium content, rather than true bioavailability. And here’s a hint, when you evaluate magnesium types using mineral physiology principles and broader magnesium literature, these claims are not supported. ------ Citations Schuette et al., 1994 Bioavailability of magnesium diglycinate vs magnesium oxide Demonstrated alternative absorption mechanisms for chelated magnesium. Coudray et al., 2005 Comparative absorption of different magnesium salts using stable isotopes Showed differences in absorption and retention across magnesium forms, salt only comparison. Schuchardt & Hahn, 2017 Intestinal absorption and factors influencing magnesium bioavailability Comprehensive review of Mg transport mechanisms (TRPM6/7, passive vs active). Werner et al., 2019 Magnesium citrate vs oxide bioavailability National Research Council (NRC), Nutrient Requirements of Horses Documents magnesium metabolism and absorption sites in horses.
