Can I Take vitamin d and calcium Together?

SUMMARY:

Vitamin D and calcium are commonly taken together and are generally compatible; vitamin D helps increase intestinal absorption of calcium so they are often co‑supplemented. Excessive doses or certain conditions can cause elevated blood calcium, so use recommended dosing and check with a clinician if you have risk factors or symptoms.

ADDITIONAL NOTES:

Mechanism: vitamin D (cholecalciferol) enhances intestinal calcium absorption. Typical use: frequently co‑prescribed or combined in supplements to support bone health. Risks: excessive supplementation or underlying conditions (for example, hyperparathyroidism, certain granulomatous diseases, or impaired kidney function) can lead to hypercalcemia/hypercalciuria and related symptoms (nausea, vomiting, weakness, increased urination, confusion); monitoring of serum calcium may be advised for high doses or at‑risk patients. Practical points: follow recommended doses on product labels or prescriber instructions; tell your clinician about all supplements and prescription medications so they can check for additional interactions.
