*sigh* Vitamin B12 is available in dairy products, and is produced by certain froms of bacteria so perhaps you should be saying eat dairy/eggs/dirt - not meat.

I agree with taking a b12 supplement now and again (hardly any is needed)- most vegans already do this in the form of fortified foods.

Examples of which include some Soya/rice milks, cereals, vitamin drinks. yeast extracts and some dairy free margarines.

Vitamin B-12 (Cobalamin) is not bioavailable in plant form. The best way to get B-12 is from Meat.

A study I found while doing some research:
http://www.ajcn.org/cgi/content/full/72/3/762

Background: Lack of cobalamin may lead to neurologic disorders, which have been reported in strict vegetarians.

Objective: The objective of this study was to investigate whether cognitive functioning is affected in adolescents (aged 10-16 y) with marginal cobalamin status as a result of being fed a macrobiotic diet up to an average age of 6 y.

Design: Data on dietary intake, psychological test performance, and biochemical variables of cobalamin status were collected from 48 adolescents who consumed macrobiotic (vegan type) diets up to the age of 6 y, subsequently followed by lactovegetarian or omnivorous diets, and from 24 subjects (aged 10-18 y) who were fed omnivorous diets from birth onward. Thirty-one subjects from the previously macrobiotic group were cobalamin deficient according to their plasma methylmalonic acid concentrations. Seventeen previously macrobiotic subjects and all control subjects had normal cobalamin status.

Results: The control subjects performed better on most psychological tests than did macrobiotic subjects with low or normal cobalamin status. A significant relation between test score and cobalamin deficiency (P = 0.01) was observed for a test measuring fluid intelligence (correlation coefficient: -0.28; 95% CI: -0.48, -0.08). This effect became more pronounced (P = 0.003) within the subgroup of macrobiotic subjects (correlation coefficient: -0.38; 95% CI: -0.62, - 0.14).

Conclusion: Our data suggest that cobalamin deficiency, in the absence of hematologic signs, may lead to impaired cognitive performance in adolescents.

More problems with B-12 deficency:

VITAMIN B-12 DEFICIENCY SHOULD BE CONCERN FOR VEGETARIAN MOTHERS
During 2001, cobalamin (vitamin B12) deficiency resulted in neurologic impairment in two children in Georgia. The children were breastfed by mothers who followed vegetarian diets. A recent report from the U.S. Centers for Disease Control and Prevention (CDC) summarizes the two cases and provides guidance for health-care providers on identifying and preventing cobalamin deficiency among breastfed infants of vegetarian mothers.



Oh, I know an easy way to Avoid B-12 deficency...EAT MORE MEAT!
