Vitamin K2 and Magnesium are required for proper utilization of vitamin D. If they are not present, Calcium can build up in the bloodstream causing multiple possible issues. Were these prescribed along with it? If not, the doctor trying to naively solve a problem without any actual critical thinking. Which is understandable given the breadth of things they have to deal with, but unfortunate. Boron may be another significant required co-factor, but I’m not read up on that one.

Basically all vitamins and minerals have very complex interactions, and if you start taking megadoses of one, then it can surprising effects like:

* Cause accelerated utilization of a co-vitamin, causing low levels in these, and rendering the megadoses vitamin ineffective.

* Block or bypass the pathways that utilize a vitamin, causing to high a levels of another vitamin.

* Rendering measurably normal levels of a vitamin ineffective, through competition or exhaustion of the resources the secondary vitamin relies on.

B vitamins for example have complex interactions with each other. I cannot offhand remember the specifics, but if I recall correctly things like “energy” drinks stuffed with megadoses of a vitamin can result in the symptoms of deficiency of another B vitamin despite having normal levels.

Prescribing Vit D without Vit K2 (and possibly) Magnesium is simply malpractice. I take Vit D myself and after a few minutes of googling it is abundantly clear that it should not be taken in isolation.
