Calcium and Vitamin D Supplement (Bone Health Supplement)
Last reviewed July 2026
Who is this for?
This is a combination supplement that contains calcium (as calcium carbonate) and Vitamin D, which work together to keep your bones strong. The Vitamin D helps your body absorb calcium properly so it actually gets into your bones and teeth.
Replenishes serum calcium by increasing intestinal calcium absorption via 1,25-dihydroxyvitamin D3 activation of vitamin D receptors, while promoting calcium reabsorption in the distal renal tubule and supporting hydroxyapatite mineralization in bone matrix. Vitamin D metabolites also regulate parathyroid hormone secretion, maintaining calcium-phosphate homeostasis and preventing secondary hyperparathyroidism-induced bone resorption.
Weak bones (osteoporosis), calcium deficiency, Vitamin D deficiency, bone pain from low calcium, prevention of bone loss especially in older women after menopause, support during pregnancy when extra calcium is needed

If you miss a dose, take it as soon as you remember. But if it is almost time for your next dose, just skip the missed one and continue your normal schedule. Do not take two tablets at once to make up for it.
Buy only from reputable pharmacies and avoid buying supplements from roadside vendors or unregistered shops as they may be fake or expired. Do not take more than the recommended dose thinking it will work faster, as too much calcium can cause serious kidney problems. If you are taking other medications, always tell your pharmacist so they can advise you on proper spacing.
Do not take this supplement at the same time as antibiotics like tetracycline or ciprofloxacin, as calcium blocks their absorption, so take them at least 2 hours apart. Iron supplements should also be taken separately, at least 2 hours before or after. If you are taking blood pressure drugs like amlodipine or other heart medications, inform your doctor before starting this supplement.
