Gut Health and Bacteria

gut health

The microbiome, which consists of trillions of bacteria, breaks down and distributes nutrients to various parts of the body. Because the GI tract communicates with the whole body, including the brain through the gut-brain axis, it is crucial to maintain gut health through an equilibrium of good bacteria in the digestive system. If harmony persists, it leads to the elimination of harmful bacteria and substances from the body. On the other hand, an unhealthy gut microbiome can induce brain fog, bloating, and infections, along with other issues.

Prebiotics, probiotics, and synbiotics comprise the gut microbiome and are at the center of gastrointestinal tract health, which plays a role in the functioning of most, if not all, bodily systems. While these bacteria are not the same, they work together. The prebiotics feed the probiotics. Synbiotics are a combination of both pre and probiotics.

Pre and Probiotics

Prebiotics and probiotics are important to gut health because they provide beneficial bacteria to the system.

Prebiotics are carbohydrates that supply food for the probiotics that work to facilitate bacterial growth and perseverance. They may aid in the absorption of nutrients, digestion, and weight loss. Probiotics contribute to the healthy bacteria found in the gut. They may assist digestion, weight loss, and the maintenance of the immune, nervous, and cardiovascular systems.


Synbiotics allow a person to intake pre and probiotics together, which ensures food for the probiotics. This combination may increase the survival rate of healthy bacteria.
