Can I take 1.25 and Zinc together?

Why this happens

Calcitriol (1.25-dihydroxyvitamin D3) increases how much calcium your body absorbs from food. Zinc can also influence calcium metabolism. When taken together, they may cause calcium levels to rise too high (hypercalcaemia). Furthermore, zinc and vitamin D share certain pathways in the body, and an excess of one can sometimes affect the balance of the other.

You should speak to your doctor or pharmacist before taking zinc supplements with calcitriol. They may want to monitor your blood calcium levels more closely. If you do take both, it is often best to space them at least 2 hours apart to reduce any direct interference in the gut.
