Hi. So if I take a b complex, womens 1 a day viatmin, and then seperate take 1000mcg of b12 that would not be too much b12 with by levels and there would be no harm? It has been a week too since the doc said to wait a week. I also take magnesium and glucosamine msn. Also for my blood work I'm skeptical because as I said though at the end of my weight gain when I was severly anorexia/under and ended up in 2 cardiac units my blood work was fine. Like how can that be? So I often am skeptical but what can one do? Thanks again
