B12…not always created equally


B12 is important to build red blood cells and nerves. It also supports proper DNA development. Most individuals who are vitamin B12 deficient on lab work, have  some preexisting condition, such as gastritis, auto immune disease, take multiple medications that deplete b12 stores or are malnourished.  Vitamin B12 tests are not the most accurate way of telling how the cells are utilizing b12, or if they are utilizing it at all. So, in fact individuals with adequate numbers on lab work could actually be deficient.  In the presence of MTHFR, B12 can look adequate or even elevated on lab work but be completely depleted inside the cell where the B12 is needed most.

Vegan and vegetarian diets are deficient in B12, posing a greater risk of deficiency in individuals with MTHFR, this can lead to other nutrient deficiencies and health problems.
