Why would people have B12 infusions? Is it more superior than SC or IM injections?
Apart from the fact that the infusion can be prepared with B12 with calcium and magnesium, I don't see any other benefit. I just wondered because injection is so much quicker and cheaper. B12 IV will go straight into the blood system but I'd say that the IM injection starts to work just as quick e.g. within 15 mins.
