I would get a hard copy...you need to know WHICH B's cause adding without knowing can land you with HIGH B6 and that is AS bad as low B12.I am only 2 months post-op and right now trying to stay on top of my vitamins has been a chore. I got labs done, and my doctor's nurse called me 2 days after to tell me I am low on Vit D, Potassium, Iron, and need to add a b-complex....yet my b-12 is high. I ordered Biotech D-50, the Vitron-C from Amazon.....waiting for it.
