I've been reading online about the practise of injecting certain vitamins. All the research I've read is pretty much split down the middle - some disregarding it as a detrimental act, some reporting with gleaming praise (including Dr. Phil's front row sitting wife, heh). Before everyone jumps on this as supplement abuse, some doctor's recommend it, and even teach patients to do it at home. Does anyone have any opinions?
I'm interested in B12 specifically. Is it worthwhile? Obviously this would be an intramuscular injection.
