PET | TAO Harmonize GI Supplement (120 Soft Chews)

PET | TAO Harmonize GI is a veterinarian-formulated soft-chew supplement that supports digestive balance and gut health in dogs and cats. Each chew delivers four digestive enzymes (Amylase, Lipase, Cellulase, and Protease), 1 billion CFU of PB6 Bacillus subtilis, 100 million CFU of Bacillus coagulans, and a Fructooligosaccharide prebiotic to nourish the beneficial bacteria. By supporting complete digestion, healthy gut flora, and intestinal barrier integrity, Harmonize GI helps pets thrive with calmer digestion, more consistent stools, and stronger immune resilience. Carries the NASC Quality Seal. Safe for dogs and cats.

What It Supports

  • Complete digestion and nutrient absorption: Four digestive enzymes break down proteins, fats, carbohydrates, and fiber to maximize nutrient availability and reduce the burden of undigested food particles in the gut
  • Healthy gut microbiome balance: PB6 Bacillus subtilis and Bacillus coagulans probiotics, combined with a Fructooligosaccharide prebiotic, support beneficial bacterial populations and help crowd out harmful microbes
  • Intestinal barrier integrity and immune resilience: A balanced gut microbiome and healthy intestinal lining support immune signaling and reduce immune overreactivity linked to skin, allergy, and digestive concerns
  • Consistent stool quality and digestive comfort: Supports calmer digestion, reduced gas and bloating, and more regular stools in dogs and cats with sensitive or imbalanced digestive systems
  • TCVM Spleen Qi and Wei Qi support: In TCVM, the Spleen transforms food into usable Qi; strengthening Spleen Qi reduces Damp accumulation, supports healthy digestion, and bolsters Wei Qi (defensive immune energy)

Active Ingredient Actions

Each ingredient in PET | TAO Harmonize GI is selected for its specific role in supporting digestive function, gut microbiome balance, and immune health, grounded in Western enzyme science and TCVM principles.

  • alpha-Amylase (Aspergillus oryzae, 2320 SKBU): Digestive enzyme that breaks down starches and carbohydrates into simple sugars for absorption; supports efficient carbohydrate digestion and reduces fermentable substrate that can disrupt gut flora balance
  • Lipase (Aspergillus niger, 210 LU): Digestive enzyme that breaks down dietary fats into fatty acids and glycerol; supports fat digestion and absorption, reduces the liver and pancreas burden, and supports healthy coat and skin from the inside out
  • Cellulase (Trichoderma longibrachiatum, 75 CMCU): Digestive enzyme that breaks down cellulose from plant-based ingredients; dogs and cats do not produce cellulase endogenously, so supplementation improves fiber digestion and supports more complete breakdown of plant-based food sources
  • Protease (Papaya, 22100 PU): Digestive enzyme derived from papaya that breaks down dietary proteins into amino acids; supports complete protein digestion, reduces the presence of undigested protein fragments that can stimulate immune reactivity, and supports intestinal barrier integrity
  • Bacillus subtilis (PB6 Probiotic, 1 Billion CFU): Spore-forming probiotic that survives stomach acid and reaches the intestines intact; actively crowds out harmful bacteria including E. coli and Clostridium, supports gut barrier integrity, improves stool quality, and strengthens immune response through the gut-associated lymphoid tissue (GALT); in TCVM, supports Spleen Qi and Wei Qi, helping digestion transform food into usable energy and reducing Damp and Heat accumulation in the gut
  • Bacillus coagulans (Probiotic, 100 Million CFU): Spore-forming probiotic that produces L-lactic acid in the intestines, supporting the growth of beneficial bacteria and discouraging harmful microbes; supports stool quality, reduces gas and bloating, and supports intestinal lining repair; in TCVM, helps cool digestive Heat and nourish Yin fluids, which is especially supportive for sensitive stomachs, stress-related digestive upset, or chronic gut irritation
  • Fructooligosaccharides (Prebiotic): Non-digestible soluble fiber that serves as a food source for beneficial gut bacteria including Lactobacillus and Bifidobacterium species; supports the growth and activity of the probiotic strains in this formula and promotes a balanced intestinal environment; in TCVM, nourishes the Yin of the intestines and supports the Spleen's transformation function

Frequently Asked Questions

What is PET | TAO Harmonize GI used for?

PET | TAO Harmonize GI is a veterinarian-formulated soft-chew supplement designed to support digestive balance, gut microbiome health, and immune resilience in dogs and cats. It combines four digestive enzymes (Amylase, Lipase, Cellulase, Protease), PB6 Bacillus subtilis (1 billion CFU), Bacillus coagulans (100 million CFU), and a Fructooligosaccharide prebiotic to support complete digestion, healthy gut flora, and intestinal barrier integrity. In TCVM, this formula strengthens Spleen Qi and Wei Qi to reduce Damp accumulation and support immune resilience from the gut.

How and when should I give Harmonize GI to my pet?

Give Harmonize GI with or just before the first bite of your pet's meal so the digestive enzymes can act on food immediately. Dogs receive 1 soft chew per 1 to 1.5 cups of food at each feeding. Small cats (5 to 8 lbs) receive 1/4 chew twice daily with meals; large cats (over 8 lbs) receive 1/2 chew twice daily with meals. Consistent use with meals delivers the most benefit for digestion, stool quality, and long-term gut balance.

My vet recommended Harmonize GI for my dog's itchy skin. How does gut support help with skin?

Many allergy and skin symptoms begin in the gut. Approximately 70% of the immune system resides in the gut, and when the intestinal barrier becomes irritated or overly permeable, inflammatory molecules can circulate systemically and show up as itching, ear infections, hot spots, or chronic paw licking. In TCVM, weak Spleen Qi and accumulated Damp and Heat often manifest as skin-level symptoms. Harmonize GI supports more complete protein digestion (reducing undigested fragments that can trigger immune reactivity), restores beneficial gut bacteria, and strengthens intestinal barrier integrity. As the gut environment stabilizes, many dogs experience calmer, more resilient skin over time.

How long does it take to see improvement with Harmonize GI?

Some pets show improvement in stool quality, gas, and digestive comfort within the first one to two weeks as the gut environment begins to shift. Immune-related concerns such as itching, ear irritation, or seasonal sensitivities often take longer, as the microbiome needs time to rebalance and the intestinal lining must gradually repair. With consistent daily use and appropriate dietary support, most pets experience meaningful improvements in both digestion and immune resilience within four to eight weeks.

  • I have a 10-year-old, 43-lb., neutered Wheaten Terrier who has successfully lived with lymphoma for five years (after being given only weeks to live upon diagnosis). Among other supplements (including Max's Formula and MycoForte), to support his digestion we have been giving him Thorne Gastriplex in capsule form, but Thorne has discontinued that product. I am interested in your Support GI, yet I have not found dosing requirements on your site, so I don't know how much to order. Please let me know what you suggest.

    Thank you for your question! We have a free ebook download about Cushing's that will help you. We also recommend reading this article to figure out the appropriate diet for your dog with Cushing's and also adding Harmonize GI supplement and Complement Immune supplement, along with liver treats.

  • My dog has megaesophagus due to myasthenia gravis. I would like to make her food and wondered if you could offer suggestions. Also, would the Harmonize GI be good for her? Thanks!

    Thanks for your question! In general, we recommend feeding your dog in an elevated manner by placing the food bowl above the point of shoulder at multiple small feedings (3-4 per day). Feed wet food consistency of oatmeal. A warming food, such as Blaze would be best, along with Spleen treats, and Harmonize GI Supplement to aid with digestion and provide adequate probiotics. You can find a homecooked recipe version of Blaze here. Also, be aware of respiratoiry rate as dogs with megaesophagus are prone to aspiration pneumonia. If breaths per minute increases over normal or chronic coughing occurs, then get an exam from your vet for possible aspiration.

  • In the process of researching supplements for my 13 yo shitzu poodle that was diagnosed with cushings disease in May. I have decided to make his food so want to make sure he gets what he needs. What do you recommend? Thanks!

    Thanks for your question, Jenny! It is wonderful you've decided to make your dog's food, we applaud your decision! We believe homecooking is the best option for pets. When convenience is needed, there are wonderful commercial TCVM foods out there as well. 

    The vendor of Harmonize GI, PET | TAO, has some recipes on their blog you can follow to cook at home for your dog.

    Here's a good article to read to start: https://pettao.com/cook-dog-cushings-disease/

    They even have recipes designed especially for early, mid, and late-stage Cushing's!

    Here's a link to those: https://pettao.com/?s=Cushing%27s

  • Hello, My labrador retriever is fearful but improving with diet and shen calmer. She has occasional fear anxiety attacks causing trembling that lead to diarrhea for several days. It doesn't happen very often and most times is unexpected like the drums from a marching band at the school as we walked by :) Will this product help keep her stools more solid during these episodes?

    Hi! Thank you for your question!

    PET | TAO Harmonize GI Supplement (120 Soft Chews) and PET | TAO Freeze Dried Beef Spleen Dog And Cat Treats (3oz Bag) could help and it's great you're trying Shen Calmer. You may need additional prescription medicine (this is the case for some pets). However, some pets are helped by a probiotic alone and you can try it. Some customers continue giving the Harmonize GI to their pets to build up beneficial gut bacteria for the future even though it didn't get rid of current diarrhea.

    If you have any other questions or if we can help you in any way, just let us know!

    Thank you for supporting Traditional Chinese Veterinary Medicine!

Perfect product

My dog loves these and the results are evident. No grass eating, better stool…better gut health. I buy two jars at a time so we never run out!

Nancy, thank you for taking the time to leave us a 5-star review. I am happy to hear your dog has great results with Harmonize GI and that they are highly palatable. Thanks for your patience while we were out of stock, too. We appreciate your business! Sincerely, Samantha

A must have

I love the Pet Tao foods I feed my dog, the healthy benefits and perfect weight management they provide. Her coat, teeth and energy couldn’t be better. My dog does, however, like to “snack” on things outside, especially as a puppy! And some of that can disrupt her GI tract. The Harmonize GI Supplement is the perfect answer to that. She’s three now and grazes on things less, but as a human Functional Nutritionist, I know the value to us and pets of a healthy gut, and this supplement is doing the job with each meal.

Fantastic!

GI Harmonize provides a gut supplement for my dogs. Before using the product my fur babies had irregular stools. Since using the GI Harmonize they have had less GI problems. Makes for a very happy dog and mom.
