Hi Bub, I too am taking Vit. D as my last blood work showed I was deficient in Vit. D. I was taking one drop a day, (I don’t tolerate the tablets well) and my family doctor told me to take two drops a day. As I understand it, Vit. D props up the immune system which is crucial in coping with cancer, but I would suggest you speak with your doctor for some direction on this. Sunlight also helps, but there again, one can’t have too much exposure to the sun these days. Good luck with it.
