Pure Encapsulations

• POWERFUL ANTIOXIDANT: Alpha Lipoic Acid(ALA) the universal anti-oxidant is vital to your health, but sometimes your body doesn't have enough. It exists as R-ALA and S-ALA. R-ALA is the only version found in nature and the version your body needs. S-ALA is unnatural, and a synthetic byproduct created during the production process.
• STABILIZED & HIGH POTENCY: R-ALA the High Potency supplement when not formulated correctly can be useless. Once R-ALA is connected to Sodium(Na), it is STABILIZED, which prevents the R-ALA from becoming unstable and prevent it from polymerizing and becoming inactive.
• HIGH ABSORPTION: Stabilized R-Alpha Lipoic Acid has been shown to have 40x more absorption to help produce desirable biological actions and bind to key enzymes.
• CONTAINS NO S-ALPHA LIPOIC ACID: Typical ALA products are a combination of both R and S versions of ALA, meaning 50% of the product is spent on an ineffective and hindering product.
• SUPPLEMENT FACTS BOXES: With so many Alpha Lipoic Acid to choose from, always confirm the Supplement Facts box on the label states "STABILIZED (Na) R-Alpha Lipoic Acid" and that it does not list “S”-Alpha Lipoic Acid.
