PET | TAO Complement Immune Supplement (120 Soft Chews)

PET | TAO Complement Immune is a veterinarian-formulated medicinal mushroom supplement for dogs and cats that supports immune function, antioxidant defense, liver health, and overall vitality. Each soft chew delivers a targeted blend of four medicinal mushrooms (Reishi, Shiitake, Turkey Tail, and Maitake), Milk Thistle, Vitamin C, CoQ-10, Selenium, Vitamin A, and Vitamin E.

  • Support during conventional treatment: Formulated to complement antibiotic therapy, help mitigate side effects of chemotherapy, and support immune resilience during steroid use

Frequently Asked Questions

What is PET | TAO Complement Immune used for?

PET | TAO Complement Immune is a veterinarian-formulated medicinal mushroom supplement for dogs and cats designed to support immune system function, antioxidant defense, liver health, and overall vitality. It is especially beneficial for pets with immune-related health concerns, those undergoing conventional treatment such as chemotherapy or antibiotics, or any pet whose overall resilience and vitality could benefit from foundational immune support. For use in dogs and cats over 12 weeks of age.

How do the medicinal mushrooms in Complement Immune work from a TCVM perspective?

In TCVM, medicinal mushrooms are classical Qi tonics that work adaptogenically to support the body's foundational energy rather than targeting individual symptoms. Reishi (Ling Zhi) tonifies Heart and Lung Qi and calms Shen; Shiitake (Xiang Gu) tonifies Spleen and Stomach Qi; Turkey Tail (Yun Zhi) clears Damp-Heat and strengthens Wei Qi (defensive immune energy); and Maitake (Hui Shu Hua) tonifies Spleen and Kidney Qi while supporting fluid metabolism. Together, they help deficient pets build strength, stressed pets stabilize, and aging pets maintain long-term balance and vitality.

Can Complement Immune be given to pets undergoing chemotherapy or other conventional treatment?

Complement Immune is formulated to complement conventional treatment, including helping mitigate chemotherapy side effects, supporting immune resilience during antibiotic therapy, and helping buffer some effects of steroid use. Always consult your veterinarian before combining this supplement with prescription medications or active treatment protocols, as individual patient needs vary.

How should I give Complement Immune to my pet, and how long before I see results?

Give soft chews during or after a meal to reduce the chance of digestive upset. You can split the daily amount between morning and evening feedings. Follow the weight-based dosing above and your veterinarian's guidance if your veterinarian recommends a dose different from the label. Immune support supplements generally require consistent use over several weeks before meaningful improvements become apparent; responses vary by individual animal, health status, and diet.

QUESTIONS & ANSWERS

Ask a Question
  • My dog is diagnosed with Inflammatory Bowel Disease (IBD). Would this product be good for him?

    Thanks for your email!

    It would be good, but specifically for Inflammatory Bowel Disease (IBD) we can recommend PET | TAO Harmonize GI Supplement, PET | TAO Freeze Dried Beef Spleen Dog And Cat Treats, PET | TAO Chill Freeze-Dried Raw Formula or PET | TAO Harmony Limited Ingredient Canned.

  • My 10 years old feline was diagnosed with renal neoplasia (adenocarcinoma suspected) and multiple metastatic lung nodules. As well as restrictive cardiomyopathy (fractional shortening and contractility at 23.9%) and left atrium is markedly enlarged. She is on a Homeopathic remedy, prednisolone, as well as Wei Qi (Immune) Booster. However, for the past two days she does not want to eat her food when the Wei Qi is sprinkled on it. Therefore, may you please let me know if the Complement Immune supplement and the kidney, lung and heart treats, or anything else, will be beneficial for my babygirl? Thank you so much for creating TCVM for pets. They all deserve this type of care. And it gives us, pet parents the ability to treat our babies with food and supplements that will help them thrive.

    Thank you for your question, and we're so sorry your cat is struggling with cancer. We appreciate the compliments about our products and your interest in Chinese Medicine!

    For cats with cancer, we recommend Complement Immune. You can learn more about how it works here: https://pettao.com/5-ways-complement-immune-supplement-boosts-pet-immunity/ 

    Also, since your cat's lungs, kidneys, and heart are affected, we recommend alternating between Lung, Kidney, and Heart treats. Here's some more information about the Five-Element theory behind the treats and why feeding "like treats like": https://pettao.com/pet-treats/

    We also recommend feeding a Blood-building diet to cats with cancer. PET | TAO has a recipe on their site you can make at home: https://pettao.com/blood-building-cat-food-recipe/

    Also, mixing the Wei Qi Booster into some wet food, tuna broth, or tuna may help your cat eat it better. 

    Just let us know if we can help furhter. We are happy to help! 

  • My dog schnauzer has cushings. Is this the best immune support you would recommend for his condition? He’s currently on vetyrol pills daily.

    Thanks for your question! We have a number of products that can help support dogs with Cushing's disease! TCVM veterinarians usually recommend energetically cooling diets for Cushing's. Also, liver treats and Complement Immune supplement support dogs with Cushing's.  There are also herbs available for Cushing's that can treat the root causes and deficiencies that lead to Cushing's symptoms. The type of herb needed depends on your pet's specific condition. Your vet will know which herb is the right herb for your pet. These herbs have to be authorized by a vet, but all PET | TAO foods, treats, and supplements do not require authorization. You can request authorization from your vet here after talking to your vet about the right herbs for your pet: https://tcvmpet.com/pages/get-an-authorization

  • My dog refused to take turkey tail mixed with food. I worry that this will not be accepted either. How often does that happen?

    Thank you for your question! We haven't had any returns due to palatability issues since this product was released. Since this mushroom supplement is a soft chew, it may be more palatable than capsules, tablets, or powders. However, it's possible some dogs may not eat the product. We offer a 100% guarantee on all PET | TAO products. You can view our refund policy here in case your dog doesn't enjoy the soft chews.

  • My dog has mast cell tumors. If used as directed, how long before improvement is seen? Also, she is currently taking prednisone; is it safe to take both?

    Thank you for your question! All supplements take a few weeks to start working in your pet's body. No supplement has been tested to cure a condition, but the mushrooms in Complement Immune such as reishi have been shown to have anti-tumor effects. It is safe to take Complement Immune along with other medicines. Learn more here: https://pettao.com/?s=complement+immune

  • Will this help neutropenia

    Thank you for your question! Results may vary depending on the type of Neutropenia. Our vets think Complement Immune may help raise the amount of circulating WBCs in your pet's blood. To learn more about Complement Immune, check out these blog posts: https://pettao.com/?s=complement+immune

  • Why are there no reviews on this product?

    Thank you for your question! We are working on some new technology that will ask customers after each purchase to leave a review. We haven't implemented that yet, so there are no reminders going to our current customers asking for reviews. Also, many of our customers purchase through vet clinics or stores, and not through our site, which has left the product pages lacking in reviews. It is something we're continually trying to improve and work on!

  • Have you thought about removing the rosemary? Rosemary is a seizure trigger for dogs w/seizures. I would LOVE to give this product a try - it has great ingredients - but can't take the chance of lowering Jesse's seizure threshold. So disappointing...:-)

    Thank you for your question! PET | TAO's veterinarians believe the amount of rosemary in Complement Immune isn't high enough to lower a pet's seizure threshold. We do recommend showing Complement Immune's product label and ingredient list to your veterinarian to see if they approve of its use in your pet. Thank you for your interest in Chinese Medicine and the powerful mushrooms in PET | TAO's Complement Immune!

  • PET | TAO Complement Immune Supplement - I have a 9 yr old with allergies and 2 mast cell tumors low 2 in 4 months. I feed nutritionists prescribed home-cooked diet and supplement with multi vitamin copper, Choline, omega 3, Calcium carbonate and Phosphate, Quercetin and Canine System Saver. I see the Vitamin A – 1,050 IU, Is this too much Vitamin A considering he is already receiving A in his multivitamin? I am interested in the combination of mushrooms but feel the added vitamins may be too much considering he is already receiving them in his multi.

    Thank you for your question! I'm sorry to hear your dog is struggling with allergies and mast cell tumors, what a tough combination. Complement Immune is a supplement that can support both of these conditions in dogs and cats. According to the Merck Veterinary Manual, the Vitamin A requirement for dogs is 3,333 IU/kg of diet fed, with up to 333,300 IU/kg of diet considered to be safe. So, even a small (2lb dog) could get up to 333,300 IU and it would be considered safe. If you'd like to double check, I'd recommend checking out your vet's opinion of Complement Immune to see if they think it would be safe in conjunction with the other great food therapy techniques you're using. If you'd like more informaiton on Complement Immune and the immune-boosting mushroom ingredients in it, go here: https://pettao.com/?s=complement+immune+. Thank you for supporting Traditional Chinese Veterinary Medicine, and best of luck in your home-cooking adventures!

  • My dog has been recently diagnosed with Cushing's disease. He produces to many steroids & has begun the medication, Vetoryl 60 mg. capsules daily. Will be re-evaluated in 30 days. We did talk about supplements (pre and pro biotics and something for joint health) & diet, however, have not made any decisions since its only been 3 days. He is 8 yrs. old. Which of these supplements do you recommend we begin him on?

    Thanks for your question! If your vet recommends a probiotic and joint supplement, check out PET | TAO Harmonize GI and PET | TAO Harmonize Joint. From a TCVM perspective, dogs with Cushing's are often supported by an energetically cooling diet. Check out PET | TAO Chill and see what you think! We also carry Eastern herbs to support dogs with Cushing's. Check with your vet to see if any of these fit your dog's situation - then, request authorization here: https://tcvmpet.com/pages/get-an-authorization.

    Thanks for your question! 
    For dogs that are 51-100 pounds, give 2 soft chews twice daily. For dogs that are over 100 pounds, give 3 soft chews twice daily. This supplement is a great complement to food therapy and herbs.

Cat would not eat it

I tried everything to get my cat to eat the product but he wasn’t interested. I would suggest creating a softer treat-like texture and something that can mask the smell of the ingredients. It was a flop for my cat.

They don’t (7) animals eat it, even crushed and sprinkled

Incredible!!

I can’t believe the positive results I’ve had with this supplement!! This will be a staple for my cats diet

Thank you so much for your positive review, Rachel! It means the world to us that you and your cat love our Complement Immune mushroom supplement and that your cat is feeling better. Please don't hesitate to reach out if you need anything further or have any questions about your cat's protocol. We are so thankful for your business.

Difficult to administer

My cat who has a blood borne cancer won’t readily eat these so I divide it into two doses and manually administer them. I noticed an improvement in the first couple of weeks but then it declined. I opted to start an oral pill of chemotherapy that she’s responding to.

Julia Wright
Dogs love them!

So I’ve tried other mushroom supplements that the dogs hate. No problem getting all 6 dogs to take these!!! Was critical for us to find something all of them could take regularly. Their lineage is prone to cancer and this is crucial to their longevity.
