Not sure. Seeing R/Os in June for my 2 year follow up and will asked. I don't know the parameters of the long term sudy. I know I had to sign a lot of privacy forms and fill out very long forms that took a hour to complete. Every question you could think of was asked and ever more I would never even thought of. The study includes additional office visits wiht R/Os but it mainly goes over every question on study form and more.

I know when I was treated UFHPTI they tell their patients to not take supplements that they identified as anti oxidants. It is a huge list. Problem was I was taking most of them. They did show the conflicting research on if does affect radiation treatments or not.

There long term researh may or may not include what you mentioned about supplements but the study does include those questions. I know they were adamant that even a multi vitiman if it had any amounts over RMD you could not even take a multivitamin and no additional supplements on the list.

I was taking Fish Oil per cardiologist but had to come off that also. But I was taking so many supplements to help with prostrate and some for other parts of body like resveratrol, lycopene, pumpkin seed oil, etc. I was told could take Co-Q-10 which was good as helps reduce the pain from taking a statin drug.
