Probiotics are live yeast and bacteria that help regulate the digestive system. They help balance the bad bacteria in our gut that can lead to diarrhea and digestive problems. Probiotics have been shown to improve irritable bowel syndrome, inflammatory bowel disease, and diarrhea caused by medications (antibiotics) and infections (bacteria, parasites, viruses). It can be helpful in treating allergies, eczema, and boosts vaginal, urinary, and oral health.
