RE: your last sentence. High dose supplementation of vitamin D should be done after consulting with your doctor (like you did). As a fat soluble vitamin, our bodies sometimes struggle to dispose of the excess. Therefore a person with "normal" vitamin D levels who begins supplementing at high levels is potentially risking some side effects. It's always good to be monitored in situations like those.

It seems you are doing exactly that, which is great.
