Gut-Brain Axis: How Probiotics Promote Health

The gut-brain axis is a fascinating two-way communication system between your gastrointestinal tract (GI tract) and your central nervous system (CNS). It is a biochemical signaling pathway like a bridge to provide a better connection. The two systems communicate to provide a better “plan” for your general health.

There are trillions of microorganisms reside in the body, especially in your gut. These information are sent through the gut brain axis to relay the message and to allow the brain to react to what we have and what we need. Important neurotransmitters that plays a role in mood regulation such as serotonin, dopamine and GABA are also produced and absorbed in the gut. Therefore, some experts also refer the gut as the “second brain” as it contains neural networks similar to those in your central nervous system. 

In some cases, harmful microbes can disrupt the harmony and lead to an imbalance in the microbiome, and this is how probiotics fit in. Probiotics are beneficial living microorganisms that can control harmful microbes and restore the balance, alongside preventing episodes of imbalances from occurring. 

Not all probiotics are created equal. Although different strains of probiotics are indicated differently, quality of probiotics are important as it will affect the health of your gut brain axis. Always go for top quality products where good manufacturing practices are practiced. Always go for products with clinical evidence and supported or endorsed by physicians and pharmacists.
