Vitamin B12 deficiency is way more common than most conventional physicians are willing to admit. The literature states that only 7% of the population is deficient, but t the current limit of 200 ng/ml is probably too low. Neurological symptoms can be experienced in the low-normal range, and western medicine ignores this fact. Using functional medicine standards, which are higher, nearly half of the population may be suffering from B12 deficiency. Data from the Tufts University Framingham Offspring Study suggests that 40 percent of people between 26 and 83 have plasma B12 levels in the low-normal range. Most surprising to the researchers was that low B12 levels were as common in younger people as in the elderly. This is alarming as children suffer irreparable neurological damage with chronic B12 deficiency. Today I would like to talk about B12 deficiency and how to avoid it.
