Some user reviews are helpful, others not so much. If people say they have experienced side effects from using a product, this is something I want to know about.

User comments about dosages of a product can also be helpful. For example, I was taking benfotiamine for nerve pain at a dosage of 150 mg daily as suggested on the product label. I didn’t notice any benefit. Then I read a review where a user said the product was effective for him at a dose of 600 mg daily. This prompted me to do a little more research, and when I upped my dosage I did get better results.
