Can someone tell me the differences/ benefits etc of alpha lioric acid and R-liporic acid ? There is so much info and both that trying to really see what works best for Idiopathic Small Nerve Fiber Neuropathy plus also being recently diagnosed with pre-diabetes ( right on the edge of pre) , I want to take which ever one is the best to help both plus some of the other supplements I's trying to help. I've read about the Nerve Formula ( or neuropathy formula ad on web) also that seems to have lots of the things I'm taking but it is all in one . As i hope it all can help the burning feet and legs in the long run.
