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 of high-dose magnesium regimens. 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. Weight: 0.5 lbs
