For most adults, taking calcium and vitamin D3 at the recommended doses is safe. Nevertheless, there are situations in which it is worth consulting a doctor before starting.
- Pregnancy and breastfeeding. The need for calcium increases during these periods, but the optimal dose and whether a supplement is appropriate are determined individually.
- Chronic kidney disease. The kidneys take part in regulating the levels of calcium and vitamin D in the body. If their function is impaired, additional intake of these substances requires monitoring.
- Hypercalcaemia and hypercalciuria (raised calcium levels in the blood or urine) — conditions in which additional calcium is contraindicated.
- Taking certain medicines. Calcium can affect the absorption of some drugs — for example, certain antibiotics (tetracyclines, fluoroquinolones), iron preparations and thyroid hormones. An interval of 2–4 hours between taking them and calcium is usually recommended.
- Already taking calcium or vitamin D. If your diet includes other supplements with these nutrients, it is important to take the total daily dose into account.
