For instance, there are those that are the best probiotics for weight loss while some are best for the immune system. When these bacteria enter our bodies through food or supplements, they interact with our existing gut microbiome—the collection of microbes living in our intestines—to help balance its composition and promote a healthier environment for beneficial microorganisms.
The science behind probiotics is quite fascinating. First off, it’s important to understand that there are many different strains of probiotic bacteria, each with their own unique characteristics and benefits.
This is accomplished by competing for nutrients such as sugars or proteins which both beneficial and harmful bacteria need to survive. The good guys win out because they’re better adapted to utilize those resources than their competitors. As a result, the bad guys get pushed out while the good guys flourish – creating an overall healthier gut environment!
