    Probiotics may alleviate your stomach woes and other symptoms.
    Probiotics are organisms found in foods, such as yogurt, miso, and soft cheeses, as well as dietary supplements. They contain "friendly" or "good" bacteria that may help rebalance microorganisms in the large intestine. Although there is evidence that probiotics may help treat or prevent many disorders, most experts agree that longer, better studies are needed for widespread use. That said, most people can safely add foods that contain probiotics to their diets, but check with your doctor if you’re considering taking supplements. Keep these potential probiotic benefits in mind for your digestive and overall health.
