Promotes Intense Digestive Relief

Organic Bone Broth could heal leaky gut syndrome and protects non-leaky guts. The Gelatin found in our broth seals holes in the gut and targets chronic gut issues and autoimmune disease.

Helps Repair The Gut Lining

Ultra Absorb L-Glutamine has been proven to seal cracks, holes and fissures in the gut lining that lead to bloating, gas, discomfort, pain, reflux, food intolerances, constipation and loose stools.

Prevents Aging and Mood Disorders

Collagen peptides not only help repair the gut lining, but they can also regenerate skin, hair, muscles and joints. Prebiotics help prevent anxiety and depression by working at the gut-brain axis.

The Complete Gut Repair System is a done-for-you natural system. All it takes is 3 scoops per day. The system works to gently repair the digestive tract and rejuvenate the entire body without any disruptions to daily routines.

The 3 formulas work synergistically to adapt to each body’s unique requirements:

Science-Backed Benefits of The Complete Gut Repair System

Organic bone broth promotes sustainable weight loss by reducing the amounts of Firmicutes in your gut. These bacteria extract more calories from meals, which makes weight loss harder than it should be.

Collagen is 36% more filling than other proteins, which can reduce sugar cravings, snacking and overeating. Collagen is also known for making skin smoother and reducing wrinkles and fine lines.

Bone broth helps strengthen bones by providing all the nutrients they need: calcium, protein, magnesium, phosphorus, vitamin D, potassium, zinc, manganese, copper, selenium, boron, iron, vitamin K, vitamin A, vitamin C and B vitamins.  

Prebiotics help power good bacteria while crowding out the bad ones. This helps reduce symptoms associated with yeast overgrowth, helps with nutrient absorption and can prevent mood disorders by working at the gut-brain axis.

Inflammation and cellular damage have been identified as “hallmarks” of a leaky gut. Recent scientific evidence shows that system-wide inflammation levels may be significantly lower in people who take L-Glutamine than in those who do not take it.

Prebiotics can help with weight loss by turning dietary intake into energy instead of promoting storage in the form of fat. They also promote a well-functioning immune system and help the body stay protected throughout the seasons.

Ultra Absorb L-Glutamine promotes rapid cell regeneration to start restoring the gut lining (within 30 days or less). It can enable the gut cells (enterocytes) to regenerate at faster levels which seal the tight junctions in the gut and can restore the gut lining to a healthy state faster.  

The collagen and other healing nutrients in our formulas help seal holes in the gut lining and balance the microbiome for better digestion, mood and brainpower. The makeup of gut bacteria (known as the microbiome) modulates mood, energy levels, the ability to learn, and stress responses.
