I live in a more northern location and get a rash if I expose my skin to the spring, summer and fall sun for more than 5 or 10 minutes at a time without protection, so supplements are important.
I get my vit D from my calcium supplement, soy milk, fortified OJ and vit D supplements. If you google vitamin D, you'll find a lot of information on natural sources (including Wikipedia).
I thought I was crazy, but I get the same rash, only just first thing in the spring!
