Our take on the Professional Formulas R(+) Alpha Lipoic Acid Caps

Professional Formulas R(+) Alpha Lipoic Acid is a single-ingredient antioxidant supplement supplying 300 mg of the R(+) form of alpha lipoic acid per capsule. The R(+) isomer is the naturally occurring form, and this product delivers it alone rather than as the common 50/50 racemic mix, so each capsule gives a full 300 mg of the active isomer. It is gluten free, vegetarian and hypo-allergenic, with a simple capsule and no added colors or binders beyond basic excipients. It suits people who want a clean, single-ingredient ALA capsule and are willing to take it three times daily as directed.
