That's a very interesting article Trinity. How ironic is the suggestion that the reason we no longer produce our own source of B12 is due to the introduction of meat into the diet!

Hi Amber, a tricky one indeed, thanks for sharing. For me the bacteria based supplements from the herbalist/health food store felt like a better option than the artificially produced B12 they put in the injections. On the positive side the only other ingredients in the injection were salt and water (compared to the extra ingredients in some of the other more medical supplements I explored!) The injection is usually hydroxocobalamin (if you are in the UK at least), from what I understand this is a combination of cyanocobalamin (not so easily absorbed and less beneficial for humans) and methylcobalamin (best type). You can request an injection of the latter if you feel inclined. Best wishes with the exploration.

Love, Fiona
