ALA is a dithiol compound that functions as a cofactor for mitochondrial alpha-keto acid dehydrogenases (pyruvate dehydrogenase, alpha-ketoglutarate dehydrogenase). Both ALA and its reduced form DHLA are potent antioxidants capable of regenerating other antioxidants including vitamin C, vitamin E, and glutathione. ALA activates AMPK, improving glucose uptake via GLUT4 translocation, and modulates NF-kB-mediated inflammatory signaling. It chelates redox-active metals (Fe2+, Cu2+).

Curcumin modulates over 100 molecular targets. Primary mechanisms include direct inhibition of NF-kB nuclear translocation (master inflammatory transcription factor), suppression of COX-2 and iNOS expression, inhibition of STAT3 and AP-1 signaling, and activation of Nrf2-ARE pathway upregulating Phase II detoxification enzymes (glutathione S-transferase, heme oxygenase-1). It also inhibits mTOR signaling and modulates epigenetic enzymes (HATs, HDACs, DNMTs).
