Doctor's Best Stabilized R-Lipoic Acid contains BioEnhanced® Na-RALA, the sodium salt of R-Lipoic acid (RLA). Unlike pure RLA, BioEnhanced® Na-RALA is a stabilized form of RLA that won't degrade at high temperatures, is more bioavailable than regular RLA and has no solvent residues.*

Lipoic acid (LA) plays an important role in glucose metabolism and energy production. LA, when manufactured, occurs in two molecular forms, designated "R" and "S." The "S" form does not occur naturally in living systems and studies clearly indicate that the "R" form, RLA, is more biologically active than the "S" form. This formula includes the vitamin biotin to further support lipoic acid's metabolic benefits.

Essential for energy generation by mitochondria* Helps promote the body's antioxidant defenses* Helps maintain healthy blood sugar levels already within the normal range*

Benfotiamine is a highly bioavailable derivative of thiamin that can support the circulatory and nervous systems. Alpha-Lipoic acid (ALA) is a key factor in the cellular process that metabolizes glucose for energy production. ALA has the capacity to impact heart, eye, and brain health. Benfotiamine + ALA is a winning combination to support healthy aging and to maintain healthy cells in the presence of circulating glucose.
