- supports neurological function
- antioxidant in both water- and fat-soluble tissues
- essential for liver, eye, and nerve health
- the form of supplemental lipoic acid found in highest concentration in the bloodstream
Alpha-lipoic acid (ALA) contains two forms designated as R-lipoic acid (R-ALA) and S-lipoic acid (S-ALA) that are mirror images of each other. Naturally occurring ALA in the R form functions as an essential cofactor for many enzymes involved in energy production. In addition, R-lipoic acid has significant antioxidant effects that contribute to liver, nerve, and eye health.
Thorne Research provides R-lipoic acid bound to sodium the most bioavailable form of R-lipoic acid.
