More than just a food flavor enhancer, black pepper offers health benefits thanks to its bioactive compounds, with piperine being the most important. Piperine is a natural alkaloid that gives black pepper its pungent taste. It is also the main component that gives black pepper its health-boosting qualities. This pungent spice contains a variety of active compounds, specifically oleoresins and alkaloids like piperine and chavicine. It also has antioxidants, flavonoids, essential oil, and other phenolic compounds that help protect your cells and boost digestive health.
