What is M3 serious gut illness-inducing bacteria?

M3 is a group of serious illness-inducing bacteria in the gut. A Renowned University in Hong Kong discovered that the subjects who had serious illness-inducing bacteria had higher levels of M3 bacteria in the gut in contrast with the healthy cohort by metagenomic sequencing and big data.


How do G-NiiB M3XTRA SMT04 and G-NiiB Immunity+ Formula SIM01 differ?

G-NiiB M3XTRA SMT04 targets and combats M3 bacteria, helping to restore the gut's natural defenses and enhance its protective barrier. It's specifically formulated for individuals experiencing gut-related issues such as bloating, gastrointestinal discomfort, diarrhea, and gut sensitivity.

On the other hand, G-NiiB Immunity+ Formula SIM01 focuses on fortifying the gut with beneficial microbes to boost overall immunity, with clinical evidence supporting its effectiveness in reducing infections and enhancing skin, mood, and sleep. It's recommended for anyone over the age of two who is looking to improve their gut health and immunity.


What role does Tara Gum play in G-NiiB M3XTRA SMT04?

Tara Gum, derived from the seeds of the Caesalpinia Spinosa plant, is a natural food-grade additive that has been shown to work in tandem with the live probiotics in G-NiiB M3XTRA SMT04. The combination is clinically recognized and patented, with Tara Gum enhancing the probiotics' ability to adhere to the intestinal lining, reinforcing the gut's mucosal barrier, and preventing potential irritants from triggering allergic responses.


Is it advisable to combine G-NiiB M3XTRA SMT04 with other probiotic brands?

While taking various probiotic products simultaneously is not typically harmful, it is not recommended. Probiotics need adequate prebiotics and space to thrive in the gut. Introducing too many different probiotic strains at once can lead to unnecessary competition for these resources, potentially diminishing the benefits you'd otherwise receive from a more targeted probiotic regimen.
