Is b complex vitamin good for cancer patient ? and does surbex xt medicine contain b complex vitamin?

Unknown &controversy: There is not enough science to answer this definitively. I think yes. One of the best studies was done by abam hoffer md who showed dramatic increases in survival in cancer patients who took high doses of b complex, beta carotene, e, c, selenium & zinc. See http://cancertherapies.Org/bkinfo.Htm no one has studied b vits alone. Surbex xt has four b vitamins but not the full b complex.
