Adverse effects
Possible side effects include gastrointestinal problems, for example nausea and constipation. If very high doses are taken, signs of hypercalcaemia (abnormally high blood calcium levels) have been described, such as stomach pain, vomiting, thirst, and tiredness. Extreme or long-term or overdose can theoretically result in hypervitaminosis D, kidney stones, chronic kidney disease, and calcinosis.[1][2]

Calcium forms complexes with a number of pharmaceutical drugs, reducing their bioavailability; among them are tetracyclines, quinolone antibiotics, levothyroxine, and bisphosphonates, as well as iron, magnesium and zinc supplements. Vitamin D in usual doses has no relevant interactions.[2]
