Policy Vitamin B12 deficiency, sometimes called cobalamin deficiency, happens when your body is either not getting enough or not absorbing enough vitamin B12 from the foods you eat
However, this decision is highly individual and depends entirely on the specific cause and severity of your B12 deficiency, as well as your bodys unique absorption capabilities
That may relate to vasovagal response, low hydration, or nutrient impact on blood pressure
Epidemiological evidence in some cases hints that the accepted dosages of vitamin B helps only to avoid their marginal deficiency and further benefits could accrue from higher dosages than those provided by RDA (4-5)
