Vitamin D tests are not necessarily one of the “standard tests”. (Maybe in the future.) You could call the doctor’s office and ask them if it was one of the tests and if by chance it was, ask them for the “level”. Do not settle for it was “in range”, you want the exact number. If they did not take one, you could ask for one. If that doesn’t work, then the VDC sells test kits. It would be really great to know what your starting level is but if you cannot do this, then you can try the following.
We usually recommend 5000iu a day of Vitamin D3 for a person weighing 150lbs. If you are extremely deficit, then usually you take more than that for 8 weeks and then retest your levels to make sure they have improved to a “healthy level”. For us this means a minimum level of 50ng/ml. If your levels are then “high” enough, you can then probably take a maintenance dosage of 5000iu, forever. If you weigh more, than you have to take more. So you can try anywhere from 5000-10,000iu a day. If you take the higher amount, I would do so until you feel well again, then try a lower maintenance dose which for you may be more like 6-7000iu a day.
If you decide to take a lower dose and you do not feel better in 8 weeks, come back and tell me.
The anxiety is probably coming from a lack of Vitamin D but might also come from a lack of magnesium. So if you start taking the Vitamin D and the anxiety gets worse, then it is because you need to take a magnesium supplement. (Vitamin D uses a lot of magnesium.) Sometimes people have to stop taking the D and take several days to a week of magnesium before trying the D again.
I would keep taking the B12 for the time being.
You need to read http://www.vitamindcouncil.org/about-vitamin-d/vitamin-d-and-other-vitamins-and-minerals/. It is very important!
Vitamin D should only make you feel better not worse. So if your symptoms get any worse or different ones appear, then come back and tell me. (It is usually a mineral deficiency.)
Everyone in your family should be taking Vitamin D!
If you have more questions, just ask!
There is a connection to low vitamin D levels and diverticulitis.
