Zusammenfassung
Das zweiwertige Erdalkalimetall Kalzium (Ca) ist mengenmäßig mit 28 mol pro 70 kg Körpergewicht das dominierende Kation des menschlichen Körpers und stellt dabei den wichtigsten Baustein von Zähnen und Knochen dar. Die empfohlene Kalziumzufuhr beträgt 0,8 g/Tag. Von der täglich oral zugeführten Menge werden 25–40% im Ileum resorbiert. Der Grad der Resorption ist um so höher, je niedriger die Kalziumzufuhr ist. Die Ausscheidung erfolgt zu ca. 85% über den Darm und zu etwa 15% über die Nieren. Die ▶ Homöostase des Kalziumhaushaltes unterliegt in erster Linie der Regulation von Calcitonin, Parathormon (PTH) und 1,25(OH)2- Cholecal-ciferol, der aktiven Form des Vitamin D.
