I posted this question on the site for those of us who have neuropathy that’s unrelated to diabetes. Mine is a result of a mistake during surgery that damaged the intercostal nerve.

I’m asking for information on the highly recommended R-alpha lipoic acid. My primary said YES immediately about my taking it. My question is what is the difference between R-alph and just alpha lipoic acid. I can Google it, but I thought someone might have knowledge and experience.
I’m aware Vitamin E with a dl is synthetic and I wouldn’t take it. Is this similar? Thanks!
