I have been using puritan's methylcobalamin 5000mcg every day for long time(almost an year). My condition improved a bit in the middle but now going back to the old symptoms. Recently I consulted a doctor and he prescribed two Princi-B-Forte(B1-250mg, B6-250mg and B12-1000mg) tables per day. But the B12 in the tablet is cyanocobalamin. I don't want to discontinue my methylcobalamin intake. Can I use both? will there be any side effects to that.
I could not get tablets only with B1 and B6 in it.
Thanks in advance for your suggestions.
