I am a diabetic and this product was recommended by my doctor as a non-prescription method of controlling foot pain. I do not take insulin and my sugars are pretty well controlled with pills. I am currently using 900 mg, taken in the evening. I could tell the difference when I did not take the Benfotiamine for 2 days last week. This product works for me at this time.
