Contraindications & warnings

ANTICOAGULANT INTERACTION: potent antiplatelet effects — avoid with warfarin, aspirin, and other anticoagulants/antiplatelets. Drug interactions: CYP3A4 inhibition, P-gp inhibition, CYP1A2 inhibition. Iron chelation — reduces iron absorption. Hepatotoxicity reports (rare, mainly at very high doses). Gallstone disease: stimulates bile secretion — caution. Pregnancy: avoid concentrated extracts (uterine stimulant at high doses).

About

Primary curcuminoid from turmeric. Anti-inflammatory (NF-κB and COX-2 inhibition), antioxidant, and potential anti-cancer properties. Poor oral bioavailability without formulation technology. Very large number of clinical trials.

Mechanism of action

Potent NF-kB inhibitor (blocking IKK phosphorylation of IkBa). Inhibits COX-2 and 5-lipoxygenase. Activates Nrf2 and HO-1 antioxidant pathway. Inhibits VEGF-mediated angiogenesis. Chelates redox-active metals. Poor bioavailability requires piperine or phospholipid complex.
