Just my opinion, I don't believe in fooling with all the snake oils that are out there. If they would cure cancer, or keep us from getting it, that's what chemo would be, drink a glass of blueberry juice and take this powder. I'm sure some of those things will help as a vitamin. but if I get cancer for the 4th time, I will gladly take the radiation, chemo, or both.
Lot's of people believe in them, that's fine. But reality is what it is.
Hope you do well in your recovery, and welcome to the site. Lot's of good people here with lot's of answers
