We shouldn't be telling people to overdose on Vitamin D, obviously. I dread the day that Donald Trump mentions "Vitamin D", but then again even a massive overdose of Vitamin D isn't going to be life-threatening. The generally safe amount is 4000 IU daily, which should get almost everybody to healthy levels. However, if your doctor finds that you have low levels, he may prescribe far higher amounts for a while.
