We were told the same thing and believe me, you don't want anything to interfere with your treatment (Gordon was getting Cisplatin). Drop the supplements. Not taking them for a couple of months is the least of your problems, and you can always get back to them after your treatment is finished. Check with your Dr. before you start taking them again.
