Does B6 interfere with Sinemet? I read in Good Nutrition in Parkinson's Disease put out by the APDA that, "B6 does not worsen PD if used in the recommended amount of 2 mg. per day. If supplemental vitamins are used, intake should not exceed 5 mg. B6-free multivitamins are only needed if a person is taking levadopa rather than Sinemet." (p.14) Has anyone heard the contrary? Thank you for any response! Michelle
