"Vitamin B-12 deficiency and depletion are common in wealthier countries, particularly among the elderly, and are most prevalent in poorer populations around the world. This prevalence was underestimated in the past for several reasons, including the erroneous belief that deficiency is unlikely except in strict vegetarians or patients with pernicious anemia, and that it usually takes ≈20 y for stores of the vitamin to become depleted." http://ajcn.nutrition.org/content/89/2/693S.full http://ajcn.nutrition.org/content/89/2/693S.full "Vitamin B12 deficiency is a common but under-recognized, yet easily treatable disorder in older adults. Although several causes exist, food-cobalamin malabsorption is now believed to be the most common etiology." http://www.ncbi.nlm.nih.gov/pubmed/12650116 http://www.ncbi.nlm.nih.gov/pubmed/12650116 Older adults because it can take 20 years+ for deficiencies to become apparent. http://chriskresser.com/b12-deficiency-a-silent-epidemic-with-serious-consequences http://chriskresser.com/b12-deficiency-a-silent-epidemic-wit...

"The only place I've ever even seen this claim is on vegan advocacy forums as unsubstantiated claims or in studies of nutrition absorption problems as a general factor in the elderly." I'm looking for non-elderly studies, who, because of general age-related issues suffer from all-around nutritional deficiencies. In other words, we already know old people are sick in a variety of ways, I'm challenging you to support your claim, directed to non-vegans that > you too, are likely to be running a vitamin B12 deficiency I want to say it's absurdly untrue and laughable on its face, but I'm willing to eat my words if you can produce a couple independent studies that demonstrate your claim without citing some unattributed nonsense from veganforum.com or other rubbish filled site.
