Sooth & Support

Glutamine directly supports gut health 3 ways: it aids the balance of the gut microbiome, increases tight junction proteins and the integrity of the intestinal lining, and helps to minimize the inflammatory response in situations of gut mucosal irritation.


Promote Optimal Gut Health

NatureKnit™ delivers dietary fiber and polyphenols to the gut. These fiber-bound polyphenols are slowly released and act as antioxidants.

 

Improve Microbiome & Gut Immunity

MicrobiomeX® promotes a shift in the gut microbiome that leads to a beneficial short-chain fatty acid (SCFA) profile. This improves gut barrier function and enhances the immunity in the gut.†



Lower Digestive Symptoms & Reduce Bloating

GutGard® is show in 2 studies to significantly lower the symptoms of daily digestive health problems and provide relief from H. pylori for 48% of those studied.†

 

Background

Tight openings in the intestinal walls allow water and nutrients to pass through into the bloodstream while keeping harmful substances inside. The rate of this passing is known as intestinal permeability (IP). As gut health declines with age, stress, poor diet and unhealthy lifestyle, these openings become looser. This allows food particles, bacteria, and toxins to leak directly into the bloodstream. If neglected, the increase in Intestinal Permeability (IP) may contribute to various health conditions. Poor IP has some early warning signs such as diarrhea, constipation or bloating, fatigue, headaches, poor focus, unhealthy skin, joint pain and or poorly resolved inflammatory events. Advanced Gut Care contains clinically studied ingredients that aid the balance of the gut microbiome, soothe the intestinal tract, and support the integrity of the intestinal lining. †
