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 so glad you were able to check the bottle. His issue is the D2 and he should get better with the D3.
No, I would not bother testing him before starting any D3.
I would have him take 10,000 iu a day for 8 weeks and then get him retested to make sure his level has risen to 50ng/ml or more. If he is not totally better at 8 weeks, then he should keep taking the 10.000 iu.
If he has any gastro issues then get the spray, if not he should do fine on pills/capsules.
You need to read the following at http://www.vitamindcouncil.org/about-vitamin-d/vitamin-d-and-other-vitamins-and-minerals/. It is very important. Vitamin D3 uses a lot of magnesium to process things and if there is not enough in his diet, then the Vitamin D3 might give him symptoms. (If you supplement, do not use magnesium oxide get one that ends in “ate” like citrate. It absorbs better.) One thing not covered in the above is calcium. If he does have Osteomalacia then he needs to rebuild bones. That also takes calcium. So either enough in his diet or use a supplement for awhile.
If you have any more questions, just ask.
Please come back and let me know how he is doing in 8 weeks. I would hope that he will see some gradual improvement but if nothing has changed in 4 weeks, then come back and tell me.
