Vitamin D is one of the few vitamins that can be produced in the body, but it can also be absorbed via dietary measures. If your gut is in good condition, foods like salmon, egg yolks, and milk are some great ways to give yourself a dietary boost of this fat soluble vitamin. Alternatively, one of the easiest methods of staving deficiency is to simply kiss the sun….think: human photosynthesis! It works like this: UV rays convert a type of cholesterol that is found in skin into something called Vitamin D3. The D3 form then gets processed further by your liver, then kidneys, into an active form of vitamin D called calcitriol. The most popular role of this vitamin is linked to calcium levels and bone health maintenance. However, less know that vitamin D also plays an important role in taming the immune system, which has likely gone haywire in people who can’t tolerate gluten. For these people, sunlight plus supplements may be the solution.
Coming from California, getting enough sun was never an issue…because back on the best coast…getting sun just happens. It wasn’t until I started paying attention to the quality of my skin that I realized: no sun + gluten intolerance = zilch Vitamin D. I had to do something about it.
As with all things in life, balance is key. Too much sun invites skin cancer, and although it is rare to have too much vitamin D supplementation, toxic levels can lead to damage of the kidneys. So how do you approach this balancing act of risks and benefits? Before slathering on goops of anti-UV, allow 10-15 minutes for the sun to do its thang so that you don’t have to pop these ginormous pills…but if you do decide to supplement, make sure you aren’t overdoing it, and as always, let your doc in on the plan so that vitamin D levels can be monitored properly!
