@greenacres Hi again, I buy Bestvite Benfotiamine 300mg. on Amazon. I take 2 pills a day, for a total of 600mg. Occasionally, I take 900 mgs., or 3 pills. Within about 2 days of taking it, my pain totally changed, and got way better. It's like a miracle. I had breast cancer 3 years ago, and was left with terrible foot neuropathy. What I think happened to me, after extensive reading about Benfotiamine, is that my breast tumor lowered my thiamine levels, causing neuropathy. It is the only thing that makes sense, as I have had every test imaginable to figure out what caused it, and only taking Benfotiamine lowered my pain. It just makes me think that I must have been low in thiamine, as tumors can lower thiamine levels. I suggest that you do give it a try. No harm in it. Also, I take Alpha Lipoic Acid in the form on NA R-Alpha Lipoic Acid from the company Immunovites, also bought on Amazon. The pills are 600 mg., and I take 2 a day. It is not as clear to me whether this lowered my pain, because I was already in significantly lower pain from the Benfotiamine. But there is such good research on NA R-Alpha Lipoic Acid, that I thought it could not form. You must take this form for the Alpha Lipoic Acid to be best absorbed. Anyway, I never imagined that I would be doing better, but I am. I would suggest to start with the Benfotiamine, for at least a month, and then add the NA R-Alpha Lipoic Acid. Take one at a time to start, so you can see more clearly what it does. I hope that you get some relief. Living with this illness is intensely hard, when it is not controlled. My best to you, LoriRenee1
