Alpha-lipoic acid (ALA) contains two forms designated as R-lipoic acid (R-ALA) and S-lipoic acid (S-ALA) that are mirror images of each other. Naturally occurring ALA in the R form functions as an essential cofactor for many enzymes involved in energy production. In addition, R-lipoic acid has significant antioxidant effects that contribute to liver, nerve, and eye health.
