I have been taking 200 mcg of b6 and 1000 mcg of b12 on a daily basis for some time now. is this safe/beneficial to do along with a multivitamin?

Why take pills?: Why take pills surrounded by a sheath when you can get the vitamins naturally surrounded by other vitamins, enzymes, co-enzymes, precursors, activators, antioxidants and other synergistic nutrients? See http://ods.Od.Nih.Gov/factsheets/vitaminb6-healthprofessional/ for excellent natural sources of b6. For b12, look no further than wild fish like alaskan salmon.
