Probiotics are live microorganisms that, when consumed in adequate amounts, confer health benefits on the host. These beneficial bacteria and yeast can be found in various foods, supplements, and fermented products. They play a crucial role in maintaining the delicate balance of the gut microbiome, which is essential for overall health and well-being. These microorganisms, primarily from the Lactobacillus and Bifidobacterium genera, help promote a healthy digestive system by aiding in the digestion and absorption of nutrients, as well as supporting a strong immune system. They work by competing with harmful microorganisms for space and resources in the gut, thereby preventing the growth of harmful bacteria that could cause digestive issues. Probiotics have been linked to several potential health benefits, including the alleviation of digestive issues such as diarrhea, constipation, and irritable bowel syndrome.
