Dr. Holick shares if a woman can overdose on vitamin D.

Dr. Holick:
You can definitely overdose on vitamin D, but you have to take huge amounts of vitamin D to do so. Usually, you have to take more than 10,000 units of vitamin D a day for at least half a year before you even have to begin to worry about vitamin D intoxication.

Now the normal range for the 25-hydroxy vitamin D is 30 to 100, but you could easily go even up to 150 because we see lifeguards that are outside all the time, making lots of vitamin D. They are at 125 nanograms per milliliter. They are not vitamin D toxic. So vitamin D is relatively safe, but you do have to be careful, and you don’t want to overdose on vitamin D.
