@cynbell I go online to Amazon. The price is good. MY Neurologist sold it in his office and it was expensive. NO WAY! Also you might pay more in med stores where they sell different meds also expensive. On Amazon they sell Nutricost alpha lipoic acid and for 240 capsules it’s 24.89. I would look a bit for sure. I use the Nutricost alpha lipoic acid. I have had no problem with it. @rnlorena
