Life Extension Super R-Lipoic Acid 240mg (60 Capsules)
by Life Extension
"240mg Bio-Enhanced R-lipoic acid (not racemic) — the mitochondrial antioxidant that regenerates vitamins C, E, and glutathione"
Overview
Life Extension Super R-Lipoic Acid provides 240mg of Bio-Enhanced R-lipoic acid per capsule. This is the R-isomer only — not the racemic (R/S) alpha-lipoic acid found in most supplements. The R-isomer is the biologically active form that the body naturally produces, and it's 12x more bioavailable than racemic ALA. R-lipoic acid is unique among antioxidants because it's both water-soluble and fat-soluble, allowing it to work in every compartment of the cell. It also regenerates other antioxidants (vitamins C, E, CoQ10, and glutathione) back to their active forms. R-lipoic acid is a cofactor for mitochondrial enzymes (pyruvate dehydrogenase, alpha-ketoglutarate dehydrogenase), directly supporting ATP production.
