I saw there was another question about vitamin D; however, I do not believe this is a repeat. What are some of the effects/side effects of having too much vitamin D in your body?

That is a rare condition that can only occur when taking too much doses of vitamin D. It has nothing to do with sun exposure.

High levels of vitamin D stimulate hypercalcemia and all its negative consequences. It can also exacerbate liver and kidney chronic diseases.

Reference: Katherine Zeratsky, What is vitamin D toxicity, and should I worry about it since I take supplements?
