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?
Before I go any further can I confirm one more time since we seem to be having a misunderstanding.
He was taking 100,000 iu (one hundred thousand) of Vitamin D PER DAY (not once a week or once a month) for an ENTIRE YEAR without his level increasing???
