Probiotics are live microorganisms found in yogurt and other fermented foods, supplements, and even beauty products. Probiotics may work by: ✅ maintaining a healthy gut by improving digestion and reducing gas and bloating ✅ influencing the body's immune response by reducing the risk of infection and protecting against antibiotic-associated diarrhea. If you are currently taking an antibiotic, talk to our pharmacist to see if adding a probiotic to your regimen is right for you.
