Intestinal disorders and digestive problems are quite common in pets, can be non-specific and may recur. The two powdered tree barks in this herbal nutritional supplement have a soothing effect on the digestive tract, slowing the passage of food and increasing absorption of nutrients, firming stools and easing discomfort.

Easily digestible, the gentle action of Tree Barks Powder means it is suitable for use in weaning, during recovery from illness and alongside medication in animals with conditions such as exocrine pancreatic insufficiency.

It’s also a good short term choice in animals experiencing bouts of diarrhoea and in the recovery period afterwards, providing relief from intestinal discomfort and for longer term recurrent problems.

Dogs can develop a leaky gut often caused by poor diet, drugs and other toxins (steroids, flea and tick treatments, anti-biotics) and over vaccination. Dogs can also be born with leaky gut passed on by the mother.

Leaky Gut can be the core issue of imbalances such as:

  • Allergies
  • Skin conditions
  • Ear infections
  • Eye problems
  • Collapsing trachea
  • Digestive problems
  • Low energy
  • Behavioural issues
  • Joint pain
  • Bad breath
  • Autoimmune conditions
  • Liver, pancreas or gallbladderIn case of extreme allergies where you know there is a large yeast overgrowth, the Yeasty Beast Protocol should be used first to rid the digestive tract of systemic yeast.

So, what does it do?

Rather than suppressing the issue, leaky gut protocol helps targets the root cause of the above listed issues and to repair the foundation of the gut. The leaky gut protocol will help the mucosal junctions to heal and close.

Leaky Gut consists of five Adored Beast products:

Product 1 (pre-step): Anti-Vaccinosis Removes the associated vaccine side effects without removing any vaccine benefits.

Product 2: Liver Tonic -detox/organ support Helps regenerate healthy liver cells and boosts the organ’s ability to filtertoxins from the blood. Aids in proper function of histamine (associated with allergies, chronic inflammation), protein synthesis and biochemical production for digestion.

Product 3: Healthy Gut -digestive enzyme/ pre and probioticHelps rebalance and cultivate proper growing conditions for friendly digestive flora destroyed through antibiotics and toxins. Aids in the digestion of food supporting less reactivity in the blood stream until the gut heals and supports a healthy immune system.

Product 4: Gut Soothe -replenish/anti-inflammatory/pre and probioticA proprietary blend of herbs, nutraceuticals and pre & probiotics that soothe and replenish the lining of the bowel, fight yeast and combats unhealthy bacteria. With 30billion CFU wide-spectrum probiotic.

Product 5: Gut Seal -strengthener A homeopathic remedy that helps restore, strengthen and tighten the separated “leaky” junctions of the gastrointestinal lining. Consult labels for ingredient list, instructions and dosages.

How to use it?

5-Step Kit Complete the 2 day pre-step Anti-Vaccinosis before moving onto the other products.After completing the 2-day pre-step, begin products 2, 3, 4 and 5 at the same time. These products can be given in food together, as directed.Note: If your dog has a sensitive stomach it is recommended that Healthy Gut is given at 1/2 the recommended dose, slowly working up to a full dose over the course of 1-2 weeks.

DIGESTIX® for Dogs and Cats is a blend of the three major groups of enzymes designed to enhance the digestion of high protein / low carb diets. It helps the breakdown of protein, fat and carbohydrate in conjunction with the body’s own enzymes. It contains a wide range of proteases, lipase and amylase from fungal sources designed to be active throughout the gastrointestinal tract. While less expensive supplemental enzymes from animal sources generally do not survive the acidic conditions of the stomach, fungal microbial enzymes are especially resistant to stomach acid. The digestive enzyme supplements used in Digestix® have proven efficacy throughout the GI tract. The enzyme activity of each of the components is determined and reported according to standard Food Chemical Codex procedures recognized by the FDA.

Background Information about Enzymes

Enzymes are specialized proteins that play a key role in mediating and speeding specific biochemical reactions in the body. Digestive enzymes are usually grouped into three distinct classes, depending on the major food groups they help break down: proteases (breakdown of proteins), lipases (breakdown of fats) and carbohydrases (breakdown of carbohydrates). Each enzyme is specific to the action it performs—enzymes do not do general work. Some enzymes are rapidly broken down in the acidic environment of the stomach, while others are active in the small intestines where 90% of nutrients present in the food are absorbed.

Digestive enzymes are essential for the effective breakdown of food into nutrients that can then be assimilated. Enzymatic breakdown is a multi-stage process that starts when food contacts saliva, continues in the stomach and is completed in the small intestine where specialized enzymes further split apart the mass of food and digestive fluids into the molecular structures of the various nutrients so they may be absorbed into the circulatory systems.

Enzymes are produced in various parts along the digestive tract. With increasing age, enzyme production slows down, and digestion becomes less effective. Use of supplemental digestive enzymes therefore makes increasing sense as our companion animals get older. When taken together with food, supplemental digestive enzymes are completely dedicated to the digestive process, while the same enzymes taken on an empty stomach are partially absorbed intact into the bloodstream where they appear to help restore and maintain healthy blood and tissue functions, and can have a beneficial effect on immune and inflammatory processes.

Digestix® Formula

Digestix® is a premium blend of digestive enzymes designed to optimize the digestion of typical canine and feline diets. It is contained in a tasty chewable tablet, making it very easy to offer companion animals. Digestix® is composed of enzymes and the Vitamin B Complex, carefully selected for their specificity and functionality.
