Vitamin B12 plays a very important role in neurological function, affecting memory and balance when blood levels are low. A new study shows impressively low levels of B12 measured in the brain were related to decreased neurological function and memory impairment in the elderly, as well as those with autism and schizophrenia.
“These are particularly significant findings because the differences we found in brain B12 with aging, autism and schizophrenia are not seen in the blood, which is where B12 levels are usually measured.” said Dr. Richard Deth, Ph.D., professor of pharmacology at Nova Southeastern University’s (NSU) College of Pharmacy. “The large deficits of brain B12 from individuals with autism and schizophrenia could help explain why patients suffering from these disorders experience neurological and neuropsychiatric symptoms.”
What foods have the most Vitamin B12?
“…Meat, poultry, eggs, dairy products and wild-caught fish. Leafy green vegetables, beans and peas also provide some B vitamins, but if you eat an all vegetarian or vegan diet, vitamin B12 is one of the nutrients your body is most likely deficient in, as it is naturally present in foods that come from animals, including meat, fish, eggs, milk and milk products.” (From Dr. Mercola – his article is interesting in that he discusses in greater detail the effects of diminished B vitamins and elevated homocysteine for increased Alzheimers and brain shrinkage.)
