Yes! Vitamin D is fantastic! I do wonder what it really does... I think that there's way more to it than anybody knows right now...

The first time I was tested (2009) my Vitamin D was at 12! I felt so much better when I started taking it, but then I felt like too much wasn't a good thing either.. I think that for me it can upset the hormonal balance in my body a bit (it's actually a hormone - not a vitamin). I'm curious to know where the research will go re finding what it interacts with besides thyroid hormones... It's all such a puzzle

I'll let you know what happens w the Casein Free changes, speaking of puzzle pieces..
