For a more effective alpha lipoic acid supplement, try Swanson P-Fraction Alpha Lipoic Acid. Conventional alpha lipoic acid supplements feature a racemic mixture of R and S isomers in a 50-50 ratio, but the P isomer is the only form that occurs naturally in the human body, and it is the form that accounts for most of alpha lipoic acid’s beneficial effects. While this is known, efforts to create an effective supplement using only the P form have always been hampered by stability issues. This Swanson formula achieves peak plasma concentrations of R-alpha lipoic acid 30 minutes after ingestion, which are up to 8-10 times higher than those achieved with other alpha lipoic acid supplements.
