VEGAN DAILY FACTOIDS: Vitamin B12

B12 is the most chemically complex of all the vitamins, and is the general name for a group of compounds called cobalamins.  B12 is critical for the growth and protection of the nervous system, helps prevent anemia and is needed for the proper metabolism of carbs and fats.

•  B12 is generally available in two forms – methylcobalamin, the most effective form, and cyanocobalamin, the most common and cheapest form.

•  The common and inexpensive cyanocobalamin form is difficult for the body to absorb, and the small amount that is absorbed usually fails to find its way into cells.  As a result, many people who take even large doses of cyanocobalamin continue to be deficient in the vitamin.

•  A simple alternative is to take the methylcobalamin form, preferably sublingually for best absorption.  Several brands of this form can be found here at Amazon.com.

•  Vegans must remember that we require vitamin B12 supplementation, as this vitamin is found almost exclusively in animal tissues.  Although vegans may not see any signs of deficiency for some time – the body can store up to 5 years worth of vitamin B12 – signs will eventually develop.  Those who have followed a vegan diet for more than 5 years should have B12 blood levels tested annually.
