Four Leaf Rover Gut Guard

Powerful probiotic for dogs

Together with herbs to help support a healthy gut and the immune system by feeding the bacteria and microorganisms that eat starches and fibers your dog struggles to digest.

  • Veterinary formulated Gut Guard is formulated by Holistic Veterinarian Patricia Jordan. Every ingredient has been carefully researched and sourced for its superior quality, safety and effectiveness.
  • Powerful probiotics – Gut Guard contains spore-forming probiotics that can survive the harsh conditions of the digestive tract and Pediococcus acidilactis, which is known for its ability to support distressed guts. These species form a protective shell when stressed and are more likely to survive and colonise than other species.
  • Supports a healthy gut– Gut Guard contains organic herbs and foods that help control inflammation in the digestive tract, plus natural prebiotics to help restore healthy bacteria colonies.
  • With L’glutamine to support the mucosal lining of the gut.

Your dog’s small intestine and colon are home to trillions of bacteria and microorganisms. These bugs are so critical to his health, they control most of his immune system … and can even talk directly to his brain.

These friendly bacteria eat starches and fibres your dog can’t digest and use them to manufacture beneficial metabolytes for your dog, such as his B vitamins, vitamin K, short chain fatty acids that control his immune system and inflammation, and amino acids. They also help protect your dog’s gut lining.

This delicate balance of bugs can be disrupted by the wrong food, drugs and chemicals, heavy metals and antibiotics. This can allow harmful bacteria to colonise and their metabolytes cause inflammation in the gut lining. This is called dysbiosis.

The gut lining is single layer of cells with tight spaces between. When the gut is inflamed, these spaces widen. This allows undigested protein, harmful bacteria and other inflammatory factors to escape the digestive tract and enter the body. This is called Leaky Gut. Because the toxins circulate the body and cause chronic, low-grade inflammation, leaky gut can cause chronic organ disease if not corrected.

Leaky Gut is the “great imitator” and is the root cause of many common inflammatory disorders. This includes allergies, yeast, arthritis, digestive issues, liver and kidney issues and more. If left unchecked, the chronic inflammation caused by leaky gut can even cause cancer.

Ideally use for up to 3 months at a time and discontinue once symptoms have stopped. Please consult a Vet if symptoms persist.

Fussy Bulldog

We have a very fussy bulldog and this product not only has had great health benefits but it seem to have had a real positive knock on effect with his appetite also! Great product - will be buying again and again.
