Description
Swanson R-Fraction Alpha Lipoic Acid is a step above traditional alpha lipoic acid supplements. 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 in the human body, and it's the form responsible for most of 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.
