In certain inherited diseases are applied larger amounts of vitamin B12 up to 1,000 times higher than normal needs, in order to influence the functional treatment of hereditary metabolic disorders (in humans have described four inherited disorders of cobalamin metabolism).
Vitamin B12 can be added to a vegetarian (macrobiotic) diet, given that many diets of this type, as well as many vegetarian school can cause serious deficiencies of this vitamin, especially in children. Claims that the miso, tempeh and other soy products are rich in vitamin B12 are contradicted by various studies.
