Like "Great post...Vitamin D also greatly inhibits the growth of cancer cells. My doctor told me that most people have a very low level of D in their blood. Ask for it on your next blood test....mine came out mid normal and she said it was the highest she has seen. I work hard at managing my D to stay active and would really make me mad to contract cancer after all that effort. (My mother died of pancreatic cancer ten years ago :>( I also just read a post on this site than Vitamin K2 combines with D to help minimize hardening of the arteries. Thinking of adding this to the pill box as well."
