I feel like it’s a good idea for me to mention this at least once per winter. Tons of people are deficient in vitamin D, especially now that a lot of us are using SPF more regularly. Our bodies are perfectly designed to get vitamin D through sun exposure on the skin, so well designed in fact that if you get enough sun exposure during the summer, your body will hold on to its vitamin D and use it all winter. However, if you are light skinned and didn’t end up getting 10-20 minutes of unprotected sun exposure per day during the summer or if you are darker skinned and didn’t get a bare minimum of 20-60 minutes of unprotected sun exposure per day, you may need to supplement with a vitamin D pill this winter. To know for sure you need your doc to check your levels.
Vitamin D helps in wound healing, cell differentiation, and in moderating inflammation, 3 things that are important to acne sufferers. While there is little published research attempting to link vitamin D levels to acne, it can’t hurt to make sure your levels are in the acceptable range. I would love to see more research on this in the future.
I am light skinned and I try to get unprotected sun exposure during the summer whenever I can, but I work during the day and very often don’t get the time in the sun that I like. The last time I had my vitamin D levels checked they were right on the line between acceptable and deficient, so I take a 10,000iu vitamin D pill a few times a week during the winter. 10,000iu is the upper limit recommended by the Vitamin D Council per day. Your body can produce 10,000iu – 25,000iu in a day of moderate sun exposure. When taking vitamin D, look for D3, which almost all leading authorities recommend over D2, and as always, if you have specific medical issues, be sure to talk to your doctor before supplementing.
