My wife has a vitamin / mineral problem and part of what I've found out is the Vitamin D you take is processed by the body into a Vitamin D it actually uses - they aren't the same. There could be a problem with how your body processes it so no amount of supplement will help your body to use it. I can't remember the details, and don't want muddy the waters with misremember details, but think this is called Vitamin D 1.25. The doctor/hospital is able to inject you with this 'active' type your body can use if they feel it may help.
