Doctor’s Best Stabilized R-Lipoic Acid delivers 100 mg of R-Lipoic Acid per capsule, sourced from Sodium R-alpha Lipoate (Na-RALA) — a stabilized salt form chosen for its enhanced stability compared to standard R-Lipoic Acid. R-Lipoic Acid is the naturally occurring form of alpha-lipoic acid found in the body.

Each capsule also provides 150 mcg of D-Biotin (300% NRV), alongside the R-Lipoic Acid, for a combined formula in a single daily capsule.

Formulated with a clean, minimal excipient profile and encapsulated in a vegetarian capsule, this product is suitable for vegan and vegetarian lifestyles. Free from gluten, soy, GMOs, and animal-derived ingredients, it is designed to fit a wide range of dietary preferences and needs.
