R-Alpha Lipoic Acid (R-ALA/R-isomer) is the biologically active form of alpha-lipoic acid (ALA/RS-isomer) that has demonstrated to possess all beneficial properties for acting as a natural substrate in damaged cell metabolism and glucose disposing, while optimizing the actions of insulin. R-ALA also scavenges reactive oxygen species and has clinically proven to recycle glutathione, one of the bodies most important cell regulators for maintaining a healthy life style. As a note, regular alpha-lipoic acid (ALA/RS-isomer) actually contains almost 50% of the natural R-isomer and close to 50% of the synthetic S-isomer. Almost all therapeutic mechanisms are found only in the R-isomer of ALA. It is therefore that SAN decided to release a 100% R-ALA for those individuals who are interested to supplement with the natural and biologically active form of ALA (R-isomer) instead of the synthetic ALA (RS-isomer) sold by most nutraceutical companies today.
