Question

Vitamin D toxicity: What if you get too much? What is vitamin D

toxicity, and should I worry about it since I take supplements?

Answer

from Zeratsky, R.D., L.D.

Vitamin D toxicity, also called hypervitaminosis D, is a potentially

serious but treatable medical condition that occurs when you get too

much vitamin D.

Vitamin D toxicity usually results from taking an excessive amount of

vitamin D supplements — not from your diet or too much sun exposure.

That's because your body produces only a limited amount of vitamin D

from sun exposure, and even fortified foods don't contain large

amounts of vitamin D. Although vitamin D toxicity is rare even among

people who take supplements, you may be at greater risk if you have

health problems, such as liver or kidney conditions, or if you take

thiazide-type diuretics.
