I have been using Doctor's Best Benfotiamine 150mg for about 2 months. I started with the Methyl Be 12, then added the R-lipoic and Benfotiame about 4 weeks later.

I did look up the Beriberi. There are a few symptoms - difficulty walking (cane for balance), swelling lower legs & ankles (take Furosemide 40mg and Spironolactone 25mg every a.m.)The edema started a couple of weeks after Cystocele Surgery, also developed Statsis Dermatatis following the surgery) and of course pain especially ankles & feet burning. My spine pain ongoing. Had spinal fusion along with laminectomey; had compression of a( very red angry nerve (doctor's term) about 5 years ago.

I do think the burning of ankles and feet has lessened somewhat since starting these supplements. Standing or sitting for any length of time aggravates the problem. I am thinking of trying the Benfotiamine twice a day = 300 mg total.
