Prebiotics are plant fibers that help healthy bacteria grow. You can think of prebiotics as the food for the probiotics, allowing them to grow and thrive! Prebiotics provide more long-term effects when compared to probiotics. Examples of prebiotics include green bananas, onions, garlic, and green tea.
