B12 is also able to help combat depression and chronic stress. It does this by regulating the nervous system and thereby helping to maintain homeostasis and ‘parasympathetic tone’. That is to say that the body is not too ‘wired’ in fight or flight mode, but also not too relaxed in ‘rest and digest’ states.
B12 has been shown in studies to be effective in treating and perhaps even preventing the onset of depression. So if you are concerned that this is something you may be at risk of, that’s another reason to increase your intake of red meat!
