Curcumin
Curcumin is the main polyphenol in turmeric, with anti-inflammatory and antioxidant activity. Small randomized trials suggest possible antidepressant, anti-anxiety, and osteoarthritis-pain benefits, but studies are small and heterogeneous, and curcumin’s poor absorption complicates interpretation. Evidence is preliminary and best regarded as promising rather than proven.
