R-lipoic acid is the most active isomer of alpha-lipoic acid (ALA). 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’s R-lipoic acid is bound to sodium – the most bioavailable form of R-lipoic acid.
