R–Lipoic Acid (stabilized) - 60/120 caps

R–Lipoic Acid (stabilized) - 60/120 caps | Pure Encapsulations
Stabilized potassium salt of R–lipoic acid

This potassium salt of R–lipoic acid provides a highly stable and bioavailable form of R–lipoic acid, with the potential for enhanced antioxidant protection and metabolic support.

Potassium–R–lipoate is a highly bioavailable and stable potassium salt of R–lipoic acid. Regular R–lipoic acid is heat sensitive and may polymerize extensively, decreasing its absorption significantly. In real–time stability tests, potassium–R–lipoate remained stable after 18 months.

As an added assurance, Pure Encapsulations issued an independent accelerated stability test, in which potassium–R–lipoate was stable over a simulated 18 month period. Furthermore, Pure Encapsulations R–Lipoic Acid (stabilized) delivers 100 mg of actual R–lipoic acid per capsule from 250 mg of potassium–R–lipoate salt.

The natural R isomer of alpha–lipoic acid may provide enhanced antioxidant activity, energy production, and general metabolic function. In a recent in vitro study at the Buck Institute for Aging in California, R–lipoic acid moderated oxidative stress in neurons. Additional studies suggest that R–lipoic acid offers support for glucose metabolism in skeletal muscle.

A University of California Berkeley study indicates that R–lipoic acid may be protective against age–related oxidative stress in the liver. Furthermore, a study at Oregon State University established a potential role for R–lipoic acid in protecting the heart from age–related oxidative stress.
