Stabilized R-Lipoic Acid, 100mg – 60 vcaps

Doctor’s Best Stabilized R-Lipoic Acid delivers 100mg of R-Lipoic Acid per veggie capsule, sourced from Na-RALA (sodium R-alpha lipoate). This stabilised salt form is used because pure R-Lipoic Acid is an inherently unstable molecule, prone to degrading when exposed to heat, light, or moisture — the sodium salt form remains intact at higher temperatures. Each capsule also contains 150µg of D-Biotin. The 60-capsule pot is suitable for vegans and vegetarians.

R-Lipoic Acid is the naturally occurring enantiomer of alpha-lipoic acid, a sulphur-containing fatty acid that acts as a co-enzyme in carbohydrate metabolism and plays a role in the cellular processes involved in converting glucose into energy. Alpha-lipoic acid is present in both water-soluble and fat-soluble environments within the body, making it distinctive among nutritional compounds. As a general rule, the body’s own synthesis of alpha-lipoic acid tends to decline with age.

Doctor’s Best is a science-based supplement brand with a long-standing focus on ingredient quality and manufacturing transparency. This product will appeal to those who prefer their R-Lipoic Acid in a stabilised, bioavailable form, whether they are active individuals or simply looking to complement a considered nutritional routine.
