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 think someone should read the bottle or get absolute confirmation that it is not D2 because this may be the problem why his levels do not increase.
I am not sure yet if you have to be worried about the D being “stored” or if it is an issue. Just in case if you take too much D you might get hypercalcemia. The symptoms of this include: feeling sick or being sick, poor appetite or loss of appetite, feeling very thirsty, passing urine often, constipation or diarrhea, abdominal pain, muscle weakness or pain, feeling confused, feeling tired and bone pain.
So you told me he is tired. Out of that list how many other symptoms does he have? If he truly has hypercalcemia then the doctor should check his calcium levels because they would be “high”.
