I had an allergic reaction to it. My kidneys quit working and I quit urinating. It hurt my kidneys and damaged them. I got gripped out by the neurologist not a proven treatment in the US. Germany since 1965 has used the IV Alpha Lipoic Acid and in the article says pills do not work as well. Just be careful on it. I am highly allergic to sulfa, sulfites and sulfonamides and the pharmacist said it didn’t have any sold products in it. It does. Try the R-alpha lipoic acid it can be ordered online or by your pharmacist at your pharmacy.
