JOURNAL ARTICLES:
Low vitamin B-12 status and risk of cognitive decline in older adults. (Am J Clin Nutr. 2007) "CONCLUSIONS: Low vitamin B-12 status was associated with more rapid cognitive decline. Randomized trials are required to determine the relevance of vitamin B-12 supplementation for prevention of dementia."
Prevalent vitamin B-12 deficiency in twelve-month-old guatemalan infants is predicted by maternal B-12 deficiency and infant diet. (J Nutr. 2007)
Vitamin B12 deficiency in the aged: a population-based study (Age and Ageing 2007) "Conclusion: undiagnosed vitamin B12 deficiency is remarkably common in the aged, but no specific risk group for screening can be identified. Thus, biochemical screening of unselected aged population is justified. General practitioners play a key role in diagnosing early vitamin B12 deficiency."
Vitamin B12 sources and bioavailability. (Exp Biol Med (Maywood). 2007) "The bioavailability of vitamin B(12) in healthy humans from fish meat, sheep meat, and chicken meat averaged 42%, 56%-89%, and 61%-66%, respectively. Vitamin B(12) in eggs seems to be poorly absorbed (< 9%) relative to other animal food products."
Vitamin B-12 Deficiency Is Prevalent in 35- to 64-Year-Old Chinese Adults. (J Nutr. 2007)
