Low Vit D is very very common. Just about every poster who comes here (except for about 10%) turn up very low in D.
Some have had shockingly low results in the single digits!
Here is a thread to read...with medical videos that explain the new Vit D research:

There is a study linking low Vit D to diabetic neuropathy.
As far as B12 goes, there are recommendations for seniors, 50 and over to take this supplement every day. Acid blocking drugs, used for GERD, impair absorption of B12 from food, and autoimmune disease, and low acid from aging called achlorhydria, reduce its absorption. People with gluten intolerance (wheat) develop deficiencies in many nutrients. So anyone can have impairments and not even know it.
Metformin used in type II diabetics depletes this nutrient as well.
This is my B12 thread:
