I have read that Vitamin B6 interfers with the uptake of L-dopa even in tiny amounts. Yet list members have been recomeneding a Vitamin B supplement for PD. I used to take a high dose multi-vitamin supplement but stopped when I read about B6. Is a high dose B Comlex good for PDers or not? If it is good, does anyone know how it works?
