Abstract

The calcium, phosphorus and Calcium×Phosphorus product serum levels evolved in a similar fashion in the three calcium carbonate intake forms.

Different Chemical Forms of Calcium Supplementation in Perimenopausal Patients of Differentiated Thyroid Cancer with Normal Parathormone Levels

“…CC provides one of the highest concentrations of elemental calcium (35-40%) and better absorption in the normal or acidic pH of the stomach (4). However, poor solubility in water and requirement of extra stomach acid production for absorption has been reported (5). Bioavailability in humans has been measured as high as 40% but low solubility and inconsistent absorption rate listed CC as one of the least bioavailable forms of calcium (as low as 15%) (6).…”
