For a more effective alpha lipoic acid supplement, try Swanson R-Fraction Alpha Lipoic Acid.
Conventional alpha-lipoic acid supplements feature a 50-50 racemic blend of R and S isomers, but the R isomer is the only form that occurs naturally in the human body, and it's the form responsible for most of the alpha-lipoic acid's beneficial effects.
However, efforts to make an effective supplement containing only the R form have always been hampered by stability problems - until now. This form achieves maximum R-alpha lipoic acid concentrations in plasma after 30 minutes that are up to 8-10 times greater than those reached by regular (racemic) alpha-lipoic acid supplements.
