Vitamin B-12

Many of you believe that Vitamin B-12 supplements are
critical to the health of vegans. I believe this to be pure

In 1996, Victor Herbert determined that B-12 deficiency is
rare among vegans, even though most do not take supplemental
B-12. His landmark work was published in the American
Journal of Clinical Nutrition, vol. 59(suppl), pp. 1213S-
1222S. Herbert wrote:

"To a great extent, B-12 is recycled from liver bile in the
digestive system...The enterohepatic circulation of vitamin
B-12 is very important in vitamin B-12 economy and
homeostasis...bodies reabsorb 3-5 mcg of bile vitamin B-12.
Because of this, an efficient enterohepatic circulation
keeps the adult vegan, who eats very little vitamin B-12,
from developing B-12 deficiency disease..."

Despite real science, the B-12 myth continues. If you feel
that you must eat B-12 (which is produced by bacterial
action), then buy organic carrots and be sure to eat the
unwashed roots. Washing will kill the bacteria, rich with
Vitamin B-12.
