"Pernicious anemia is due to lack of vitamin B12, which causes progressive nerve damage, forgetfulness, loss of ability to concentrate and abnormal sensations such as burning, itching and loss of feeling. However, many people with pernicious anemia do not have abnormally low blood levels of vitamin B12.

Many people cannot correct their B12 deficiency with diet because they cannot absorb enough B12 from their food.

Even the third with the lowest levels were still above a threshold used by some scientists to define vitamin B12 deficiency.
