What is super bizarre is after I had some blood work done, the doctor said I was deficient in Vitamin D and I live in Southern California. He further continued, that we often are indoors most of the time, and even when we go outside we cover up and don't get much direct exposure.

Adding to the further craziness, I asked several of my friends of their vitamin d levels and they said they were deficient also.

Live in Newport Beach, same thing happens to me, sitting inside from sunup to sundown. The one time a month I go to the beach I'm always "How have I not been outside for this long? Why do I even live here?"

I was living in Colorado, which has 300 days of sunshine a year. But the same thing happened. It was cold in the winter, even if sunny. So whenever I was out in the sun, my skin was covered completely,

That's interesting. I just moved to Colorado a year and I definitely noticed an uptick in my mood. I still take a vitamin D supplement, but I'm finding I'm having a much more consistently higher mood in the winter months than I did in Iowa.
