R-Lipoic Acid 60 caps

Alpha-lipoic acid occurs naturally as a 50/50 mixture of R-lipoic acid (R-ALA) and S-lipoic acid (S-ALA). R-lipoic acid by itself functions as an essential cofactor for many enzymes involved in energy production.* It also has characteristics, including significant antioxidant effects, that contribute to liver, brain, nerve, and eye health.* Studies indicate that supplements containing only R-lipoic acid appear to be better absorbed than supplements containing both R-lipoic acid and S-lipoic acid, with results showing twice as much ALA appearing in the bloodstream after an oral dose of R-Lipoic acid.* Because R-Lipoic acid is the form best utilized by the body, Thorne provides R-lipoic acid bound to sodium, providing it in its most stable, absorbable form.*
