Jarrow Formulas R-Alpha Lipoic Acid with Biotin comes in a 60 vegetarian capsule pack, combining two key ingredients in a single, easy-to-swallow format. Each capsule delivers 100 mg of R-Alpha Lipoic Acid, sourced from 125 mg of Sodium R-Alpha Lipoate (Na-RALA) — a bio-enhanced form chosen for its high bioavailability — alongside 150 µg of d-Biotin. R-Alpha Lipoic Acid is the naturally occurring form of alpha lipoic acid, present in plants, animals, and the human body, where it acts as a cofactor in cellular energy production and plays a role in glucose and lipid metabolism.
The inclusion of d-Biotin is deliberate: alpha lipoic acid can interfere with biotin absorption over extended periods, so Jarrow Formulas pairs the two nutrients together as a considered formulation choice. Biotin itself is a B-vitamin that contributes to normal macronutrient metabolism.
Jarrow Formulas is a well-regarded US supplement brand with a long-standing reputation for ingredient quality and transparent labelling. This product is well suited to those following a structured supplement routine who prefer their nutrients in a clean, vegetarian capsule.
