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?
First he should keep taking the 10,000iu a day for now. It would be great if you can get his Vitamin D level tested again.This will tell us a lot and where to go from here. Can you do that? If not let me know?
If so I do not think we ever established how his level is being measured as. So make sure you know whether it is ng/ml or nmol/l. The original 7 if ng/ml is terribly low. If the 7 was measured as nmol/l that translates to 3ng/ml which is “horrible” low.
