Have vitamin D insufficiency and am trying some supplements to up my optimal level.
Wanting information on this, decided to buy a book on this topic and found there were ones on vitamin 3D. So now thinking, which book is going to better explain this vitamin D insufficiency and what steps to take to correct this. Would there be a difference in the details offered on each of these vitamins...?
