Opti Mag 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. Some individuals, who take other forms of magnesium supplements, often experience GI side effects, including gas, bloating, diarrhea, constipation or a combination of these symptoms. The forms of magnesium used in Reacted Magnesium preserve GI comfort while maximizing absorption and restoring magnesium levels in the body.
