Have any of you ever got your vitamin D levels checked? I've heard a lot about getting your vitamin D levels checked recently because of how many people are low in vitamin D, especially where I live. It's never really sunny, except for two months out of the year, so I feel like I'm definitely probably deficient. I also get a lot of headaches and that's supposed to be a sign that you are deficient. So I'm wondering if I should get those levels checked or if any of you guys have ever done that.
