A chelated form of calcium for enhanced absorption is more concentrated than other calcium forms, providing more calcium per capsule.

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, or glucocorticoids such as prednisone that can increase calcium loss
• Individuals with a vitamin D deficiency – because vitamin D is necessary for calcium absorption
