At a recent checkup with my family doctor I had my vitamin D level checked and I was a bit shocked with the result. I have read in the popular press that some doctors have been expounding the values of vitamin D so I decided to investigate. You might want to get yours checked as well.
I found that my vitamin D level was at 12 ng/mL in a reference range of 20-100. Definitely deficient. This led me to the internet and it didn’t take long to find that Crohn’s patients are at risk of vitamin D deficiency, especially if they have had bowel resections. Vitamin D is a fat soluble vitamin and Crohn’s patients have a tendency for fat malabsorption, therefore are less able to absorb vitamin D. This is the most obvious answer for me as I match the Crohn’s/resection profile. I have to wonder though if other factors are at play as well. I don’t get much sun and I don’t have much vitamin D in my diet through fortified foods like milk and grain products.
Note that it is apparently possible to take too much vitamin D. A quick search will show you that there is disagreement about what constitutes vitamin D toxicity. However, it is clear that vitamin D toxicity over an extended period of time carries significant and serious consequences.
It should also be noted that vitamin D supplements have potential to interact with some medications. As always, consult with your doctor.
