Interesting about the D3. I finally bought some fish oil with D3, but I mostly prefer sunlight. I think Dr. Stephanie Seneff has written about why taking a supplement of D3 may not be beneficial like natural synthesis from sunlight.
Well, here's a reference. Sorry it's from "mommypotamus", but the info seems legit.

Vitamin D3 sulfate apparently acts differently than Vitamin D3. The sulfate form is formed in the sun.
