    Prebiotic

    With meals

    Prebiotics are non-digestible dietary fibers and compounds that selectively nourish beneficial bacteria in the gut. Common forms include inulin, fructooligosaccharides (FOS), and galactooligosaccharides (GOS), found naturally in foods like chicory root, garlic, onions, and bananas. They are widely studied for their role in shaping microbiome composition and supporting digestive health.
