In brief: List?
I'm not sure what you mean by your question? There are all kinds of lipoic acid capsules, made by many different companies.
For a good review of some that are independently tested, check https://www.Consumerlab.Com/reviews/alpha-lipoic_acid_supplements/alphalipoic/ you may need to subscribe, but $33/year is worth it since you get reviews of many products, not just this one. Good luck.
