Probiotics are live microorganisms that confer health benefits when consumed in adequate amounts. They are commonly found in fermented foods and supplements and play a crucial role in supporting gut health by balancing the gut microbiome. Probiotics can help prevent and treat gastrointestinal issues, such as diarrhea and irritable bowel syndrome, and contribute to improved digestion and nutrient absorption. Additionally, emerging research suggests that probiotics may positively influence immune function and even mental health, highlighting their significance in overall health and wellness.
