If you do not eat meat, please ensure that you are consuming Vitamin B12, If you are a vegetarian, it is very likely that you are deficient in Vitamin B-12, Iodine, and Vitamin K2 Vitamin B-12 and Vegetarians Overt B12 Deficiency B12 protects the nervous system. Without it, permanent damage can result (e.g., blindness, deafness, dementia). Fatigue, and tingling in the hands or feet, can be early signs of deficiency. Vitamin B12, like folate (aka folic acid), is needed to help red blood cells divide. In some cases, vegans may get so much folate that even with B12 deficiency, their blood cells continue to divide properly. In other cases, their blood cells will fail to divide properly and they will become fatigued and suffer from macrocytic (aka megaloblastic) anemia. veganhealth.org/articles/vitaminb12 B12 deficiency: a silent epidemic with serious consequences B12 deficiency: an invisible epidemic B12 deficiency isn’t a bizarre, mysterious disease. It’s written about in every medical textbook and its causes and effects are well-established in the scientific literature. However, B12 deficiency is far more common than most health care practitioners and the general public realize. Data from the Tufts University Framingham Offspring Study suggest that 40 percent of people between the ages of 26 and 83 have plasma B12 levels in the low normal range – a range at which many experience neurological symptoms. 9 percent had outright deficiency, and 16 percent exhibited “near deficiency”. Most surprising to the researchers was the fact that low B12 levels were as common in younger people as they were in the elderly. That said, B12 deficiency has been estimated to affect about 40% of people over 60 years of age. It’s entirely possible that at least some of the symptoms we attribute to “normal” aging – such as memory loss, cognitive decline, decreased mobility, etc. – are at least in part caused by B12 deficiency. ... Yet it is well-established in the scientific literature that people with B12 levels between 200 pg/mL and 350 pg/mL – levels considered “normal” in the U.S. – have clear B12 deficiency symptoms. Experts who specialize in the diagnosis and treatment of B12 deficiency, like Sally Pacholok R.N. and Jeffery Stewart D.O., suggest treating all patients that are symptomatic and have B12 levels less than 450 pg/mL. They also recommend treating patients with normal B12, but elevated urinary methylmalonic acid (MMA), homocysteine and/or holotranscobalamin (other markers of B12 deficiency). In Japan and Europe, the lower limit for B12 is between 500-550 pg/mL, the level associated with psychological and behavioral manifestations such as cognitive decline, dementia and memory loss. Some experts have speculated that the acceptance of higher levels as normal in Japan and the willingness to treat levels considered “normal” in the U.S. explain the low rates of Alzheimer’s and dementia in that country. ... chriskresser/b12-deficiency-a-silent-epidemic-with-serious-consequences
