Ok just was looking at Amazon , iherb and Puritan. My next question is there was a doctors best best , stablized r-lipoic acid 100 mg, 60 veg caps for 15.29. I was just wondering about that one . Also when you say 120 caps is a 2 month supply for the Benfotiamine is it a 150 mg bottle , taking 1 twice a day there isn't one that comes in 300mg is there ? I know you will be soooooooooooooo glad when you get this old woman straight on all of this but it is all so new to me and I"m still trying to learn. I"m a right brain person as I"m a semi retired art teacher if that gives you a clue lol
