How do you find out if you are b12 deficient? Can any one tell me? Do any of you have a problem with anger? I am moody alot and it only takes seconds for me to get angry. I don't even like myself this way. I feel I am losing everyone who matters to me because of it.

Vitamin b-12 is responsible for the healthy maintenance of nerves. At one time deficiency ststes were linked to depression and schizophrenia. You can tke supplements or eat a lot of leafy green vegetables (like spinach, kale).
