I apologize for my late response. I had the opportunity to meet with my Onc. My Onc thought it would be okay to take the vitamins that you recommended. I am currently taking Vitamin C, B Complex, and Vitamin D. I also purchased the vitamins from the health food store.My Onc recommendation was adding one new vitamin a week. I know you asked earlier what kind of chemo I am on and it is Adriamycin and Cytoxan. Thank you so much for your help.
