Probiotics are live bacteria that research suggests may have health benefits. Doctors may recommend probiotics to improve health and alleviate symptoms.
Probiotics are thought to improve digestive health, and they’re often used to treat diarrhea or bloating.
They may be sold as foods (e.g., yogurt and fermented products) and dietary supplements. In addition, probiotic creams are available for skin care.
Be sure to consult a physician or nutrition specialist for recommendations before changing your diet or taking probiotics or other supplements.
