R-lipoic acid is a powerful antioxidant. In the body, R-lipoic acid helps support healthy mitochondria, cellular energy, and protects against oxidative stress.¹

“R” Lipoic Acid is Biologically Active

Alpha-lipoic acid, the universal antioxidant, consists of two different forms, “R” and “S,” which have different properties.² The “R” form is the biologically active component (native to the body) that is responsible for lipoic acid’s phenomenal antioxidant effect. The “S” form is not very biologically active. Alpha-lipoic acid supplements typically consist of the “R” and “S” form in a 50/50 ratio. That means a 100 mg alpha-lipoic acid supplement usually provides 50 mg of the biologically active “R” form.

The human body normally produces and uses the “R” form of lipoic acid.³ Our product contains only the biologically active “R” form and provides a whooping 240 mg per serving!
