Intestinal microbiota is a community of microorganisms that inhabit the digestive tract. It includes different groups of microorganisms, not just one type of bacteria. The development of modern methods for examining genetic material has significantly expanded knowledge about this complex community and its diversity.
Characteristics and context
The composition of the microbiota is related to, among other things, diet, age, environment and previous health changes. There is no simple list of microbes that is perfect for everyone. The word "microbiome" is sometimes used similarly, although it may refer more broadly to the genetic material and environment of that community. Probiotic, prebiotic and microbiota are separate concepts. The product description should therefore indicate its specific characteristics, rather than promising a universal "setting" of the entire intestinal ecosystem.
Meaning and application
Microorganisms form a complex community, and their presence and relative proportions can change over time. Simply detecting a specific type of microorganism does not represent all of its functions. The environment, available ingredients and interactions also matter. Therefore, a single simple graph does not describe the entire ecosystem. Terms like "balance" are only useful when you know what exactly they mean in a given context.
In practice
A probiotic is a specific product or set of microorganisms, and the microbiota is a community that exists in the body. A prebiotic, on the other hand, is a separate type of ingredient. These concepts should not be interchanged. Also, the change in the test result does not automatically measure all aspects of health and well-being. When evaluating a product, what is most useful is its exact features and intended use, rather than a very general promise to organize the entire intestinal community.
