Jeff Nelson of VegSource recently released a video critical of vitamin B12 supplementation; some viewers commented “that’s it, I’m swearing off B12!”. Jeff showed several shocking studies concluding that high serum b12 levels and high dosages of b12 were associated with cancer and all cause mortality. Ryan digs deep into these studies and looks at what Jeff is really saying about vegans and b12 supplementation.
