Reply To: My husband who is 43 has been taking 100,00 IU of d for a year and his levels have not risen. He works outside for a living so he gets plenty of sunshine. Any suggestions or reasons why someone would not absorb vitamin d?
I am really sorry but I have one more question. I should have asked it at the beginning of this thread.
Is this D2 OR D3 he was taking. If this was a prescription in the USA the odds are it was D2. If you live in another country it may have been D3. It is very important to determine which one it is!
