Application
Lipoic acid (LA), also known as alpha lipoic acid (ALA) and thioctic acid is an organosulfur compound which is widely used as a dietary supplement in some countries marketed as an antioxidant and is available as a pharmaceutical drug in other countries.
Alpha-Lipoic Acid bulk material available today is (R/S) or (+/-) Alpha Lipoic Acid (ALA), meaning it contains a 50/50 mixture of (R-Lipoic) and unnatural (S-Lipoic) Lipoic Acid. The S-Lipoic Acid form, which is not found anywhere in nature, is a byproduct of chemical synthesis. Research indicates that not only does the human body have difficulty absorbing this unnatural version, it may inhibit the most essential properties of the R-Lipoic Acid form !
The “R” form (R Lipoic) is considered the “eutomer” (the biologically superior form) of Alpha Lipoic Acid, since it is identical to that produced by the body. Research indicates R-Lipoic Acid is responsible for most of the beneficial effects attributed to ALA.
While R Lipoic Acid is the obvious choice over Alpha Lipoic Acid, pure R-Lipoic Acid in its “free-acid” form has two major drawbacks : stability and bioavailability. Without special processing, R-Lipoic Acid is highly unstable and difficult to absorb. In fact, pharmacokinetic data reveal that while Alpha Lipoic Acid has a very low absorption rate, unstabilized R-Lipoic Acid is absorbed even worse !
As one of the largest fine chemical developers globally, Watson solved the stability issue by bringing in two other derivates R(+)-Alpha Lipoic Acid Sodium CAS 176110-81-9 and R-alpha-Lipoic acid tromethamine salt CAS 14358-90-8, being one of the world’s largest purveyor of commercially produced stabilized R-Lipoic Acid materials.
