Probiotics positively impact gut health by helping to maintain a healthy balance of gut microbiota. They are live microorganisms, typically bacteria or yeast, that when consumed in adequate amounts confer health benefits to the host, particularly in the digestive system. Probiotics support the population of beneficial bacteria in the gut, which can enhance the overall microbial balance, crowd out harmful bacteria, and improve digestive processes.

In a well-balanced gut microbiome, the likelihood of gastrointestinal issues, such as irritable bowel syndrome or diarrhea, is reduced. The presence of probiotics can also aid in the digestion of food, production of essential vitamins like K and some B vitamins, and support the immune system. This balance is crucial for optimal digestion, nutrient absorption, and maintaining the protective barrier of the gut lining.

On the other hand, eliminating all bacteria is not feasible or healthy, as not all bacteria are harmful; many are necessary for bodily functions. The statement about causing indigestion is misleading, as probiotics typically help alleviate digestive issues rather than cause them. While some microbes can provide energy through fermentation processes, the main role of probiotics is not to provide energy directly but rather to support gut health and function.
