A couple of months ago I had been feeling pretty tired, so I went to the doctor. I learned I was deficient in both Vitamin B12 and Vitamin D. My doctor put me on a 3-month prescription Vitamin D regimen and told me to take over the counter B12 supplements.
I had my follow-up test done over a week ago and both vitamins came back in the normal range. The doctor didn't seem to care that much about WHY I had a B12 deficiency (she also didn't know what foods contain B12), so I decided to go see my dietician. She's really knowledgeable and I respect her opinion.
Lots of people are Vitamin D deficient, but for a meat, egg and cheese eater like myself, a Vitamin B12 deficiency is not normal. While the dietician also could not say why I was deficient, she told me continue taking the B12 supplement (the doctor gave me no advice*) and suggested I get my B12 levels tested yearly. She said that with the supplementation I was taking, my B12 levels should have been really high, but weren't. Clearly, my body does not absorb B12 very efficiently.
A long-term Vitamin B12 deficiency can lead to all sorts of problems, some of which cannot be reversed. The deficiency is more common in people over the age of 50. Here's more information: www.health.harvard.edu/blog/vitamin-
*I'm going to find a new general practitioner. The person I used to see in that practice left, and I'm pretty unimpressed with her replacement.
