Discover the Science of Gut Health: Why Your Microbiome Matters More Than You Think

We often think of gut health as simply digestion. But science now shows your gut plays a central role in regulating cravings, blood sugar, hormones, metabolism, inflammation—and even mood. As Dr. Colleen Cutcliffe shared on the EXTEND podcast, “One of the most fascinating things that's been discovered about the [gut] microbiome is that it makes more dopamine, serotonin, and GABA than the brain... and there's actually a direct path from the gut to the brain, called the vagus nerve.”

So what does this mean for your everyday health?

Let’s break it down:

1. A Damaged Microbiome Can Drive Food Cravings

If you’re constantly reaching for sugar or carbs, it’s not just willpower—it may be your microbiome. Certain bacteria feed on sugar and influence the hunger hormones ghrelin and leptin to keep you craving more.

Support Tip: Supplementing with gut-rebalancing probiotics and nutrients that nourish the intestinal lining—such as L-glutamine, zinc carnosine, and N-acetylglucosamine—can help reset these signals and break the cycle.

2. Low Microbiome Diversity Slows Metabolism

Diversity is the hallmark of a resilient gut. When microbial variety drops, metabolic efficiency follows. Individuals with lower gut diversity are more likely to struggle with insulin sensitivity, fat storage, and energy production.

Support Tip: A microbiome diversity support plan should include a wide range of prebiotic fibers (like inulin and acacia fiber) and micronutrients like magnesium, B vitamins, and polyphenols to fuel microbial variety and cellular energy pathways.

3. Your Gut Talks to Your Brain—Literally

Over 90% of serotonin (the feel-good neurotransmitter) is produced in the gut. An unhealthy gut can manifest as anxiety, low mood, and brain fog through this gut-brain axis.

Support Tip: Look for supplements that support both mood and gut health, such as probiotics with psychobiotic strains (like Lactobacillus rhamnosus) and cellular cofactors like vitamin D, omega-3s, and phosphatidylserine.

4. Ultra-Processed Foods Starve the Gut

Gut bacteria rely on whole, fiber-rich foods to thrive—especially prebiotic fibers and plant polyphenols. Diets high in processed foods, artificial sweeteners, alcohol, and additives disrupt this balance by feeding harmful bacteria and starving beneficial strains.

Support Tip: In addition to increasing colorful fruits, vegetables, and fermented foods in your diet, consider supplementing with a broad-spectrum prebiotic and polyphenol-rich antioxidants (like quercetin, curcumin, or green tea extract) to support microbial balance and reduce inflammation in the gut lining.

5. A Healthy Microbiome Can Be Restored in Just 6 Weeks

The good news? The gut is remarkably adaptable. Research shows that with the right dietary changes and targeted support, the microbiome can begin to shift significantly in as little as six weeks.

Support Tip: Pairing dietary improvements with targeted supplementation—including probiotics, gut lining support (like L-glutamine, aloe vera extract, and zinc carnosine), and micronutrient rebalancing through tools like OligoCheck—can accelerate gut repair and help restore full-body health.

Conclusion

Gut health isn’t just about digestion—it’s the foundation of your mood, metabolism, immunity, and more. By nourishing your microbiome, protecting your intestinal lining, and correcting micronutrient deficiencies, you're investing in better energy, clearer thinking, and deeper resilience.
