Gut barrier function is essential for microbiome health

A healthy gut is a dynamic environment with three core characteristics: a balanced microbiome, a profuse and substantial mucous layer, and a robust cellular intestinal barrier. A host of daily assaults, from poor diets, stress and overtraining to excess alcohol, pesticide residues and toxin exposure, can compromise one or more of these areas! When the gut barrier system is impaired, the protective mucous layer breaks down and pathogenic bacterial species can begin to dominate, which can lead to gut, digestive, and immune function issues.

____________________________________________

Good Gut's unique blend of plant extracts and amino acids support the production of health-supporting postbiotic substances including the short-chain fatty acids (SCFA) butyrate, propionate, and acetate that support healthy cytokine balance, levels of "bad" bacteria, and healthy gut barrier function.

Building blocks for great guts!

L-proline, L-serine, L-threonine & L-cysteine

These four key amino acids are the building blocks for a thick and healthy gut barrier. Playing an important role in the production of intestinal mucosa, they have been shown to support mucin2 production and mucin synthesis in the colon. A thick and healthy mucosal barrier naturally repels toxins and supports immune function.

Citrus sinensis & citrus paradisi extracts (MicrobiomeX®)

This first-in-class Flavobiotic® is a natural citrus extract rich in polyphenols that supports digestive health and healthy gut barrier function. A scientific study using 500 mg of citrus fruit extract found a significant increase in short-chain fatty acid (SCFA) composition, suggesting that citrus polyphenols support the balance of microbial composition in the gut.

Polyphenol Blend (Oxxynea®)

A unique blend of researched polyphenols from Olive leaf extract, Grape seed extract, Pomegranate extract, Green tea extract, Grapefruit extract, Bilberry extract, White grape extract, Red grape extract, Citrus hesperidin, this polyphenol concentrate supports the growth of lactobacilli and bifidobacterium in the colon, as well as cytokine balance in the GI tract.

Postbiotic nutrition for pros (and the rest of us, too!)

Good Guts contains Flavobiotics® (a fancy name for citrus flavonoids) and concentrated polyphenolic Mediterranean plant extracts that support the production of short-chain fatty acids including butyrate, an essential fuel for intestinal epithelial cells. When healthy, these cells secrete a thick, protective mucous layer as part of the gut barrier system to shield the body from pathogens and toxins, as well as nourishing the gut's microbiome. The 4 principle amino acids – L-proline, L-serine, L-threonine and L-cysteine – play an important role in the production of the mucosal barrier, supporting the manufacture of the mucous layer that naturally repels toxins to support healthy immune function.

One of the best-known benefits of postbiotics is their ability to shift our gut microbiome towards a healthy composition. Research has shown that beneficial postbiotic compounds can support the growth, activities, and functions of probiotics and gut microbiota. You know what that means, right? Taking Good Guts helps support GREAT guts!

Frequently asked questions

Good Guts is a scientifically formulated blend of amino acids and polyphenols designed to support postbiotic production and gut barrier strength. The supplement combines four key amino acids (L-proline, L-serine, L-threonine, and L-cysteine) with concentrated plant-based polyphenolic extracts to provide targeted nutritional support for a healthy gut microbiome and strong intestinal barrier function.

Amino acids serve as essential building blocks for gut health. The specific amino acids in Good Guts - L-proline, L-serine, L-threonine, and L-cysteine - support the health of the intestinal mucosa and helps maintain the integrity of your gut lining. These amino acids for gut health play a crucial role in mucin synthesis, which creates the thick, protective mucous layer that nurtures beneficial bacteria and supports healthy immune function.

Polyphenols are powerful plant compounds that act as fuel for beneficial bacteria in your gut that in turn supports the production of helpful ‘postbiotic’ substances - the compounds produced by our helpful bacteria that nurtures human health. The polyphenol supplements in Good Guts, including extracts from olive leaf, grape seed, pomegranate, and green tea, help maintain microbial diversity and balance. Research shows these polyphenols support the growth of beneficial bacteria like lactobacilli and bifidobacterium while promoting the production of short-chain fatty acids that nourish your gut lining.

For ages 4-years and up, take 3 capsules daily with or without a meal, or as directed by your healthcare practitioner. The capsules can be opened and mixed with food or drink if preferred, making it easy to incorporate into your daily routine. Good Guts is designed to be easily added to your gut health regimen.

Good Guts is specifically formulated for gut health, combining amino acids for gut-lining support with targeted polyphenol supplements. While many amino acid supplements focus on muscle support, Good Guts uses research-backed amino acids like L-proline and L-threonine that specifically support mucin production and gut barrier integrity, along with polyphenols that fuel beneficial bacteria.

Yes, Gutsi® Good Guts is formulated to be inclusive. It's vegan-friendly, gluten-free, and doesn't contain GMOs, dairy, soy, nuts, or artificial additives. This makes it suitable for most dietary restrictions while still providing effective amino acid and polyphenol support for gut health.

Good Guts is designed to work well as part of a comprehensive gut health routine. It pairs particularly well with probiotics and prebiotics, such as other Gutsi® formulas like spore-based probiotic SporeBiotic™ and precision-prebiotic Gut Food, as the amino acids and polyphenols create an environment where beneficial bacteria can thrive. However, if you're taking medications or have specific health concerns, it's always wise to consult with your healthcare provider before starting any new supplement regimen. You can also check in with the TheraStore Naturopath team, too!
