Thorne Research R-Lipoic Acid is the most active form of alpha-lipoic acid that helps to support the eyes, liver, neurological function and nerve health.
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 is in the R form, where it functions as an essential cofactor for many enzymes involved in energy production. In addition, R-lipoic acid has important characteristics - significant antioxidant effects in particular - that contribute to liver, nerve, and eye health.
Dietary supplements of ALA are generally comprised either of R-ALA by itself or a mixture of R-ALA and S-ALA. Studies indicate the R-ALA form appears to be better absorbed, with twice as much R-ALA than S-ALA appearing in the bloodstream after an oral dose. Hence, R-ALA is the best form utilized by the body.
Thorne Research provides R-lipoic acid bound to sodium - the most bioavailable form of R-lipoic acid.Free Shipping
