My wife's doctor recommended taking 1000 mg of vitamin B-12 per day
My wife and I became vegans on July 4th. My wife's doctor recommended taking 1000 mg of vitamin B-12 per day. My wife's blood test 6 weeks later showed a B-12 result of 726 pg/mL, well within the reference interval of 211 - 946. This B-12 is inexpensive, and, apparently, effective. We are happy with it.
