The Active Ingredient Is: R-Alpha Lipoic Acid

R-Alpha Lipoic Acid is the bioactive mirror image of alpha lipoic acid and acts as a potent cellular antioxidant that participates in energy production processes. This formula also includes Biotin, which supports metabolic pathways alongside R-ALA.

This form is commonly used for its favourable bioactivity and mitochondrial uptake characteristics, contributing to its role in cellular antioxidant protection and metabolic function.

What Does R-Alpha Lipoic Acid Do?

R-Alpha Lipoic Acid assists with cellular antioxidant protection and supports normal metabolic function, including aspects of glucose metabolism as described in clinical context with this nutrient. The information aligns with EFSA and NHS-style function descriptions of antioxidant and energy-related roles.

Dr. Ziegler of the University of Ulm found that R-ALA may improve insulin sensitivity and support healthy glucose disposal, illustrating its role in metabolic health within approved functional contexts.
