Benfotiamine is marketed as a dietary supplement in most of the developed world and labeled as a pharmaceutical drug in some countries under the trade name of Milgamma (1).  It is a derivative of thiamine (Vitamin B1).  Benfotiamine is more bioavailable then thiamine salts, providing higher levels of thiamine in muscle, brain, liver, and kidney (2).

Benfotiamine is primarily used as an antioxidant in the supplement world.  It is also marketed as a treatment for diabetic neuropathy.  Benfotiamine has been studied in laboratory models of diabetic retinopathy, neuropathy, and nephropathy with some positive results (3).
