The importance of maintaining a healthy gut microbiome should be prioritized. Scientists have found that the gut microbiota has a symbiotic relationship with the immune system. A healthy gut microbiome is able to strengthen the immune system via the gut-immune axis. Therefore, increased awareness of the gut-immune axis may create new opportunities in the nutraceutical industry as brand owners start to incorporate new ingredients to boost immunity via gut health.
In the past, only immune-boosting foods especially those that are high in vitamin C content were prioritized as a measure to strengthen immune health and prevent illnesses. As technology progresses and the nutraceutical industry grows, it is found that gut health supplements can positively impact the immune health as well. In other words, a healthy gut means strong immunity.
