DiCalcium Malate is a concentrated calcium supplement designed by Thorne for individuals most at risk for calcium inadequacy. DiCalcium Malate consists of one molecule of malic acid that is bound to two molecules of calcium, which results in a compound that is 29-percent calcium – compared to calcium citrate, which is 19-percent calcium – thus resulting in more elemental calcium per capsule.Research indicates that a large proportion of the U.S. adult population does not consume the 1,300 mg of calcium the U.S. Food and Drug Administration recommends for daily dietary intake. Those individuals most at risk for inadequate calcium intake are:- Peri-menopausal and post-menopausal women- Women with irregular menstruation, particularly women in which this is due to prolonged athletic activity or strenuous military service- Individuals on a dairy-free diet- Vegetarians and vegans, because their diets are higher in plant-derived phytates and oxalates that inhibit calcium absorption- Pregnant women, particularly women with a history of gestational hypertension- Individuals on prescription and OTC medications such as antacids (H2 blockers or proton pump inhibitors) that can inhibit absorption- Individuals with a vitamin D deficiency – because vitamin D is necessary for calcium absorptionThorne's logo, text, trademarks, graphics, videos and photo images are the property of Thorne and are used with permission.
