From http://lpi.oregonstate.edu/mic/vitamins/vitamin-B12#reference92Previous reports that megadoses of vitamin C destroy vitamin B12 have not been supported (92) and may have been an artifact of the assay used to measure vitamin B12 levels (17).
Thank you so much! Also, any idea why taking even medium dose vitamin c (<= 1 g/day) causes me to have extreme soreness (similar to what lactic acid buildup/post-exercise feels like)? Could this be c's ability to assist with chelation?
