Since Vit. D is fat soluble vit,. my only explanation is that it was not absorbed properly due to me taking mineral oil for 5 months. Vit. D deficiency can also cause muscle weakness and pain and now I suspect that also caused my Fibro relapse during same period !!!!
I knew about warning that mineral oil can interfere with absorption of fat soluble vitamins, but thought that taking extra of them would prevent it - in my case it did not
If any of you are taking mineral oil, make sure to take supplements daily of vitamins A,E,D,K. Just don't overdo it without your doctors supervision because too much of those vitamins can cause toxicity. Just to make point how much I am low in vit D is that daily dose is about 400 IUD and I have to take now 50,000 !!!! once a week :pale:
All the best

!!! I did research on the net and all of the articles pointed "how nowadays vit. D deficiency is extremely rare and in third world countries "
