My concern with Vitamin D is that Mr Darwin has worked against us in this case. Our evolution gives us adequate supply EXCEPT: Our society has us bathing and cleaning off the oils needed for natural Vitamin D production. Which counteract our evolutionary ability to produce D. And since I am a Floridian, living in the sun, I am probably better off than most.

The bottom line is I supplement but not to an extreme. B, D, Mg, and CoQ10 are my daily routine.
