Curcuminoids are the active polyphenols in turmeric, with curcumin the most studied. People use them for antioxidant activity and to ease joint discomfort. They also help maintain a healthy inflammatory response. Some evidence points to benefits for heart and skin health.
Because curcuminoids are fat soluble, take them with a meal that contains fat. Adding black pepper extract (piperine) sharply improves absorption. Products come in standardized extracts, each with a different curcuminoid profile.
These supplements can interact with blood thinners. High doses may upset your stomach. Anyone with a gallbladder condition should speak with a doctor before use.
