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!

None!! Supplements are cheap and readily available. There is also B-12
in plants. And, there is no evidence that veg*ns, in general, have any B-12
issues.
