Not absorbing vitamin D?
In November, I had blood drawn for a hormone issue and I was found to have slightly low vitamin D (19 out of a 20-100 range). I began taking supplements, once a week for 12 weeks that were prescribed by doctor. I finished taking them a couple weeks ago and just went to my doctor Thursday for muscle/joint aches and pains.
My vitamin D is now lower then it was before (16 on a 30-100 scale). What would cause this to drop lower, despite taking supplements?
Could this be related to my hormonal issues? (adreenal hyperplasia or addenoma, not sure which right now).
