How does alpha-lipoic acid work?

    Last Updated: October 25, 2023

    ALA is involved in cellular respiration in the mitochondria by serving as a cofactor of the pyruvate dehydrogenase complex, a key enzyme involved in energy production.[1]

    ALA may benefit neurological health by increasing Nf-e2-related factor 2 (Nrf2), which increases phase II detoxification and antioxidant genes, potentially reducing oxidative damage.[2][3] ALA’s role in decreasing oxidative stress and inflammation may benefit vascular health as well.[4] ALA also mildly increases flow-mediated dilation (a measure of vascular function), possibly by increasing endothelium-derived nitric oxide.[5]
