Abstract
Instrumental neutron activation analysis and atomic absorption spectrometry were used to quantify trace elements in different national and multinational Ca supplements categorized on the basis of Ca with vitamin D, vitamin C and phosphate formulations. The supplements were found to contain low levels of Co, Cr and Cu with elevated amounts of Fe, K and Na. Toxic elements (As, Cd and Sb) were detected in very few samples at very low concentrations. The essential elements contribute to >3% of their respective Dietary Reference Intakes.
