My podiatrist also recommended this product. I did a thorough search and suggest that you do the same. This is essentially a vitamin B product that is overpriced because it is purchased via prescription. There were about 10 similar products when I did my search. Do your homework and you will find that you can buy a similar product on Amazon for less than $20. By the way, GRAS (generally regarded as safe) vitamins etc. are not regulated by the FDA and therefore don't need a prescription. Some doctors feel that their clients are always looking for a prescription, so this product fits that bill.
