    Curcumin

    Varies

    Curcumin is the principal polyphenol found in turmeric root (Curcuma longa), responsible for its characteristic yellow color. It has been widely studied for anti-inflammatory and antioxidant effects, though its naturally poor bioavailability means absorption-enhanced formulations are typically required for meaningful blood levels.
