Happy Gutz


Happy Gutz™ is the most advanced gut microbiome health supplement ever created. Happy Gutz™ contains the scientifically-proven dose of CoreBiome® demonstrated to help support your immune system by augmenting tight junctures in the intestinal lining.

Corebiome® promotes a healthy microbiome by:

  • Supporting digestive regularity
  • Regulating the normal inflammatory response in the gastrointestinal tract
  • Providing antioxidant protection to fight oxidative stress

We are the first company to use CoreBiome in this industry. CoreBiome is a unique derivative of a short chain fatty acid called butyrate, which is naturally produced by healthy bacteria in our gut when we eat vegetables.

For optimal gut and immune health, we need approximately 40 grams of carbohydrates from vegetables or resistant starches) that reach the colon in undigested form to produce Short Chain Fatty Acids. This helps increase butyrate levels and low levels of butyrate are associated with an unhealthy immune response.

Short Chain Fatty Acids (SCFAs) are the FOUNDATION of gut health and, arguably, human health. 95% of America is deficient in fiber 70% of the immune system resides in the gut.

Happy Gutz™ also contains 15B CFU Probiotics in the exclusive O15 Probiotic Blend plus a digestive enzyme blend.
