A member asked:

What are the symptoms of being deficient in the vitamin b-12?

A doctor has provided 1 answer

Nothing typical: B12 is but one of many vitamins and the symptoms overlap each other. B12 deficiency produces fairly typical changes in the blood. Because all of them are vital to energy metabolism the commonest symptom is fatigue but only a physician can make the diagnosis.
