Primary action: R-Alpha Lipoic Acid is a coenzyme used in energy production in cellular metabolism and functions as an ideal antioxidant.
R-Form Benefit: Conventional chemical synthesis of lipoic acid yields a mixture of R- and S-enantiomers. Lipoic acid from Alpha Science is processed in such a way as to yield the active R- isomer only with purity guaranteed to be higher than 99%.
Bioavailability of R- and S- alpha-lipoic acid has extensively been studied. After oral intake of R- and S-alpha-lipoic acid, at least a 60% higher response was found for the R-form than for the mixed (racemic) form, which would include the S-form.
