A probiotic is a live microorganism that, when administered in adequate amounts, confers a health benefit on the host. These are often "good" bacteria that help maintain a healthy gut microbiome. They can improve digestion, boost immunity, and even affect mental health. Think of them as the friendly tenants in your digestive system. They compete with harmful bacteria and help keep your gut balanced. You can find them in yogurt, fermented foods, and supplements.
