Folic Acid amplifies the effect of xeloda/5FU thus amplifying the side effects of the drug making it much more difficult to tolerate. Many multivitamins have increased B-vitamins for one reason or another. It sounds like you have found one with a reasonable amount of folic acid. 12% is not excessive and I would not anticipate an exacerbation of symptoms from taking this multivitamin. Best wishes.
