What Is Immune Harmony for Pets?

Immune Harmony is a unique patented plant sterol supplement that acts as a daily immune vitamin for dogs and cats and helps to regulate their immune system. Immune Harmony is helpful for pets with autoimmune diseases, cancer, allergies, viruses, chronic infections and more. Well tolerated by small pets.

How Immune Harmony Works

Immune Harmony works by regulating your pet's immune system, ensuring it functions at an optimal level.

    Weak Immune Response: Boosts immune function to help fight chronic infections.

    Overactive Immune System: Calms the immune system in cases of autoimmune diseases and allergies.

Plant sterols for dogs and cats have been scientifically tested in numerous studies. Immune Harmony is the only supplement that provides 280 mg of plant sterols, along with a special blend of natural ingredients designed to improve absorption and retention of the sterols and antioxidants. It also includes an essential fatty acid complex from flaxseed, which supports the digestive system and enhances the effectiveness of these nutrients.

How Do the Ingredients in Immune Harmony Help To Rebalance And Support the Immune System?

Plant sterols, also called phytosterols, are natural compounds found in plant cell membranes. Our plant sterol supplement for dogs and cats has an immune balancing effect. Studies performed in the United States and worldwide have found the plant sterols contained in Immune Harmony to be effective at preventing disease and maintaining health. The research indicates that beta sitosterol for dogs has anti-inflammatory, anti-cancer and immunomodulatory properties*. “Immunomodulatory” means to regulate or balance the immune system. Beta sitosterol for dogs and cats can activate T-cells (immune cells) and natural killer cells if the pet has a weak immune system. These cells fight foreign organisms that invade the body and also fight cancerous cells. On the other hand, if the immune system is overactive, as is the case with allergies or autoimmune disorders, beta sitosterol for dogs and cats can calm it down.

Key Benefits of Immune Harmony For Pets

Autoimmune Support: Ideal for pets with autoimmune diseases, Immune Harmony helps maintain immune balance and improve inflammatory responses associated with these conditions. Helpful for a range of autoimmune diseases, from cats with stomatitis to dogs with lupus.

Cancer Support: The plant sterols in Immune Harmony have been shown in studies to have anti-inflammatory and immunomodulatory properties. They boost natural killer cells, potentially inhibiting tumor growth and spread.

Chronic Infections: Speeds up a pet's ability to combat infections by increasing T-cell activity and reducing inflammation.

Allergies: Plant sterols help keep your pet's skin healthy by calming down inflammation, like redness and itching, and supporting the skin's protective barrier.

Viruses: Plant sterols help to activate T-cells and natural killer cells to fight virus-infected cells. Helps to reduce inflammation caused by viral infections.

Perianal Fistula Relief: Modulates immune function and reduces inflammation, potentially providing relief for pets with perianal fistulas.

If your pet is suffering from chronic infections, cancer or an autoimmune condition, using Immune Harmony as immune support for cats and dogs should be a core component of your pet’s health regimen.


"Gavin is a 7-year-old Scottish Terrier who has been my buddy since a puppy. A couple of months before he turned 3, he became listless, had a high temperature, drinking more water than usual and no appetite to eat. He was hospitalized for 3 days at a Specialty Veterinary Hospital where tests were done to rule out various issues. To help him recover he was on a variety of pills. The specialty doctors still could not figure out what was wrong with him for a couple of months eventually concluding that he was diagnosed as having “Immune-Mediated Polyarthritis (IMPA)”. I wanted him off all the medication and researched for a more homeopathic way to heal. I decided on the website “Ask Ariel”. I have ordered various products eventually using up to 7 products on a regular basis going on 4 years. Gavin is doing very well!" - Lisa, California

Gavin uses Immune Harmony, Power Probiotic, AllerEaze, K9 Yeast Defense, NOT Drops and Amazing Omegas.

#1 Choice For Pets With Autoimmune Disease

Autoimmune diseases occur when the immune system mistakenly attacks healthy cells in the body. Some studies have shown that plant sterols may help modulate the immune response and reduce inflammation*, which could potentially benefit individuals with autoimmune conditions. Cat owners have used Immune Harmony for autoimmune conditions such as stomatitis, pillow paw, rodent ulcers, and more. Dogs with autoimmune conditions such as lupus, thrombocytopenia, Immune-Mediated Polyarthritis (IMPA), and more have seen clinical improvement (see testimonials below) when using Immune Harmony.

"We wanted to let you know how well the Immune Harmony has been working for Cody, our 5 year old spaniel/border collie mix. Cody has autoimmune thrombocytopenia (his immune system attacks his platelets). He developed this in the Spring of 2008 which was about four months after we rescued him. He had to take Prednisone and Azathioprine for months to get it under control. Then we had to take him off the Azathioprine because it started affecting his liver enzymes. We slowly reduced the Prednisone to get him to the lowest dose that would keep him in remission. This kept his platelet counts between 80,000 and 120,000 which were considered adequate. The low end of the normal range for platelets is between 175,000 and 200,000 depending on the testing lab. We wanted his platelets to be as close to the normal range as possible so we didn’t have to worry about a relapse. Your site suggested Immune Harmony.

After we started giving him the Immune Harmony in Dec 2009, his platelet counts have been in the range of 160,000 to 185,000 when we have his periodic blood tests done. His most recent one which was two weeks ago was 185,000. We, as well as our vet, are thrilled with this. And, we know for a fact that it is the Immune Harmony making a difference. Because of the cost of the Immune Harmony, my husband wanted to be sure it was really working. Without my knowledge, there was a period of time before a blood test that he gave Cody the Immune Harmony only 3 times a week. When the blood test came back with results like we had been seeing before putting Cody on Immune Harmony, I just couldn’t figure out what happened and why his count had gone down. My husband told me he hadn’t been consistently giving it to Cody every day. Once he was back on the Immune Harmony daily, Cody’s counts were back up. This along with 2 ½ mg of Prednisone every other day, which is a minimal amount, has kept Cody from having a relapse. The Immune Harmony may be expensive, but it is well worth every penny to see Cody doing so well. Thank you, Susan, for keeping Cody healthy. It is wonderful working with you and your amazing staff." - Pat, Pennsylvania

Plant Sterols For Dogs And Cats With Cancer

The plant sterols and antioxidants in Immune Harmony reduce inflammation and boosts "natural killer cells". Pets with cancer usually have high inflammatory blood markers. Inflammation can fuel tumor growth and cancer spread in pets. Immune Harmony helps to reduce inflammatory markers. Scientific research also suggests that plant sterols create activity in T-cells, the "natural killer cells" that destroy cancer cells. The phytosterols help normalize the functioning of T-cells which results in increased killer cell activity.*

Immune Support For Pets With Chronic Infections

Plant sterols can help cats and dogs with chronic infections by boosting immune function, reducing inflammation, and balancing the immune system. These natural compounds enhance the activity of T-cells and natural killer cells, which are crucial for identifying and destroying infected cells. Plant sterols have anti-inflammatory properties that help reduce prolonged inflammation caused by chronic infections. Immune Harmony an effective supplement for managing and preventing chronic infections in pets.

Can Help Cats & Dogs With Allergies

Allergies in pets often result from an overactive immune system reacting to harmless substances like pollen, dust, or certain foods. Plant sterols, particularly beta-sitosterol for dogs and cats, have immunomodulatory properties that help balance the immune system. This means they can calm an overactive immune response, reducing symptoms such as itching, redness, and inflammation. Immune Harmony contains essential fatty acids extracted from flaxseed to help pets maintain skin and coat health.


"This is Pumpkin, who has been using your supplements (Immune Harmony, Power Probiotic, QUENT Drops / NOT Drops and Silver Immune Support), for about 8 months or more. He has Stomatitis, rodent ulcers, and many autoimmune issues. He has not had ANY flare ups since using the products, switching his food, and taking him off steroids which the Vet kept him on. Again, I thank you more than anything... He is my angel, and you have given me the chance at giving him the healthy life he deserves. Thank you." - Cassandra, Florida

Helps Manage Symptoms Of Feline Viruses

Plant sterols for cats can help to boost an underactive immune response. When pets have a chronic viral condition, they have a weakened immune system from the constant pressure of fighting the virus. These natural compounds, particularly beta-sitosterol, boost the activity of T-cells and natural killer cells, which identify and destroy virus-infected cells. By strengthening these cells, plant sterols may help control and reduce the viral load in cats, supporting their ability to fight off infections more effectively. A research study involving cats with FIV concluded that plant sterols helped infected cats maintain stable immune numbers, whereas cats that received the placebo showed disease progression.*

Beneficial For Dogs With Perianal Fistulas

Perianal fistulas in dogs are painful, ulcerated tracts or tunnels that form around the anus. These tracts can be deep and may extend inward, causing discomfort and inflammation. Dogs with perianal fistulas often experience symptoms such as pain, swelling, redness, discharge, and difficulty or discomfort during bowel movements. Perianal fistulas involve immune system dysfunction and chronic inflammation. Plant sterols modulate immune function and reduce inflammation, which could potentially have a positive impact on perianal fistulas.
