Probiotics meaning
Probiotics are live microorganisms, typically bacteria and yeasts, that provide health benefits when consumed in adequate amounts. They are commonly found in fermented foods such as yogurt, kefir, sauerkraut, kimchi, and dietary supplements. Probiotics help maintain a healthy balance of gut bacteria, which is essential for digestion, immune function, and overall health. They can aid in the prevention and treatment of various digestive issues, such as irritable bowel syndrome (IBS), inflammatory bowel disease (IBD), and diarrhea caused by infections or antibiotics. Regular intake of probiotics can support gut health and contribute to overall well-being.
