Reacted Magnesium provides three unique forms of highly-absorbed magnesium to ensure maximum absorption of this important macromineral. Most magnesium supplements use only a single source of magnesium, which can easily overwhelm a single pathway of absorption and limit uptake. Reacted Magnesium takes advantage of three unique pathways of absorption by providing magnesium as di-magnesium malate, magnesium citrate and magnesium glycinate for enhanced absorption, improved utilization and gastrointestinal (GI) comfort.
