There is no RX D3 at this time. (alone).

Doctors test you but still are clueless about treatment.

The general rule of thumb is 1000IU D3 for each 10ng/ml needed.

So for 50ng/ ml at the bottom of the normal range, you need 5000IU daily.

I have seen some reports that D2 is about equal to 1/2 of a D3 dose. But I can't say that is cast in stone.

There are many ways to give the Pliva D2... it is your doctor's decision as to how to use it. So you have to ask him. But for the short time you are to take it, it doesn't seem odd to me. I've seen higher. What IS important, is to get retested, and to continue with something after this initial dose. The problem does not go away with one good reading from a test.

A good exposure to sunlight is estimated to give 10,000 IUs that day.
