Probiotics are live microorganisms, often referred to as "good" bacteria, that provide health benefits when consumed in adequate amounts. They are commonly found in foods like yogurt, kefir, and sauerkraut, as well as in dietary supplements. Probiotics help maintain a healthy balance of gut bacteria, which is essential for digestion and overall well-being. These beneficial bacteria can support the immune system, improve digestion, and may even help with issues like irritable bowel syndrome (IBS) and diarrhea. By incorporating probiotics into your diet, you can promote a healthier gut and enhance your body's natural defenses against illness.
