R-ALA 200 mg | R-Alpha Lipoic Acid from Applied Nutrition is a dietary supplement in tablet form that supplements the diet with R-alpha lipoic acid. The active ingredient is considered by many to be one of the best antioxidants, essential in everyones diet. R-alpha lipoic acid is one of the enantiomers of alpha lipoic acid, commonly known as ALA. This naturally occurring isomer is a previously purified compound of S-alpha lipoic acid. Its action alone, unlike its R enantiomer, is practically useless for humans, as it does not exhibit bioavailability in our body. R-alpha lipoic acid finds excellent use among athletes as it improves the bodys insulin sensitivity and shows advanced action for increasing the absorption of nutrients such as vitamins or creatine.
