    Our GI tract contains trillions of bacteria, fungi, viruses, and other microbes that are referred to as the gut microbiome. A healthy gut microbiome contains a balance of good and bad organisms, mostly bacteria, that play an important role in many aspects of health including digestion, nutrient absorption, and immune health. We can improve our overall gut health through diet by eating a wide variety of healthy foods to create a more diverse microbiome.  




    Probiotics are the healthy microbes, or “good” bacteria, in our bodies. They help keep the “bad” bacteria in check.


    Probiotics are found in fermented foods like:


    • Yogurt

    • Kefir

    • Kombucha

    • Refrigerated sauerkraut

    • Kimchi

    • Tempeh

    • Miso




    Prebiotics are dietary fibers that our bodies cannot digest. They move through our digestive tract and are broken down into food to nourish the probiotics, helping them to grow and flourish.


    Prebiotics are found in fiber-rich, plant-based foods like:


    • Legumes

    • Whole grains

    • Fruits

    • Vegetables




    Postbiotics are the breakdown products of prebiotics and probiotics.  These substances, including amino acids and vitamins may promote the growth of good bacteria and slow the growth of bad bacteria.


    In addition to food sources, prebiotics, probiotics and postbiotics are available as dietary supplements which may help support gut health.* They are promoted for different uses based on their ingredients. Your Rite Aid pharmacist can help you find a product for your specific needs.
