Hi! I'm all for doing what you can to help recover, but I would firstly find out what kind of vitamins - and how much, then run it by your rads guy. Why? Because you're still only a few weeks out of rads. I asked my RO when I could start on my vitamins again post radiation, and he said a month - 6 weeks as my vitamins are kick a** and have greens, and antioxidants as well. - I doubled that timeline before I started - why? Because its likely there are antioxidants in the IV therapy (there are in my vitamins) ... This interferes with the radiation doing its job. Radiation is cumulative - at this point it's probably still working a bit... Why ruin that effect.?

Eventually it will be fine - as I do believe diet has a lot to do with healing etc... But his might just be a bit too soon depending on what he's planning to give you. Good luck, and I agree - with your reasoning I too had an easier time of it than most. Take care!
