It is best to avoid synthetic Alpha RS-Lipoic Acid.  This form interferes with the bioactive R-form.  Alpha R-Lipoic Acid by Biogenesis is reported to be 10 times more potent than standard Alpha RS-Lipoic Acid.

This R-form of ALA is the proper structural fit for membrane receptors and enzymes and therefore is metabolized more efficiently and with much greater potency.

Alpha Lipoic acid is a naturally occurring chemical produced by every cell in the body.  Alpha Lipoic Acid has been called the "metabolic antioxidant" by Dr. Lester Parker, considered one of the world's leading experts in antioxidant research.  Even though Lipoic acid is made naturally within the body, there is good evidence that our bodies can lose the ability to synthesize enough Lipoic acid when we need it the most.  The body produces small amounts of R-Lipoic acid necessary for metabolism, but this may not meet the needs of the body for free radical quenching.  Supplementation can produce profound therapeutic effects. 

Chronic systemic inflammation is a prerequisite for all the chronic degenerative diseases of aging.  Alpha R-Lipoic acid has a positive effect in stopping inflammation.
