Red bell pepper comes from the sweet, mild Capsicum annuum and contains almost no capsaicin. It delivers concentrated vitamin C, beta-carotene, and lycopene.
Most people get these nutrients through food. Concentrated extracts in supplement form also supply them. People use the high vitamin C content to help shore up daily immune and skin defenses.
Whole-food portions rarely cause trouble. Large doses from concentrated pills can upset sensitive stomachs.
