Support Your Cat or Dog's Immune System Naturally

When your pet's health has been compromised by a serious problem or as a result of normal aging, Immune Strengthener's blend of natural vitamins, herbs, antioxidants and mushrooms can provide immune system support to help maintain your dog or cat's overall health while supporting organ function.

This formula supplies a wide range of antioxidant ingredients to foster the maximum reduction of free radical damage to cells. It also includes some of the finest known immune-supportive herbal ingredients like Cat's Claw and Reishi, Shiitake and Maitake mushrooms, three of the most effective and commonly used mushrooms in Chinese herbal medicine.

One of the best selling and most popular items in our Only Natural Pet product line, Immune Strengthener consistently draws rave reviews from our customers. We hear from guardians dealing with all kinds of health issues in their pets; needing everything from general immune system and cardiovascular maintenance to liver & kidney support.

Carefully Selected Ingredients Provide Immune Support for Dogs and Cats

This immune support supplement contains ingredients, such as:

  • Reishi, Shiitake, and Maitake Mushrooms: Used in Traditional Chinese Medicine (TCM) for centuries, these mushrooms have immune-supporting properties that have been demonstrated consistently by modern research. The immune support benefits are attributed to their high levels of polysaccharides and their effect on key white blood cells. These mushrooms are also recognized for their support of the body's normal inflammatory response as well as their antioxidant properties.
  • Cat's Claw (Uncaria tomentosa): This powerful herb from the upper Amazon has supporting properties for the body's immune system and inflammatory response. Research suggests that the alkaloids present in the herb are the key to its immune-supporting properties. The alkaloids are believed to maintain white blood cell production and to help these critical cells isolate and attack foreign invaders.
  • Astragalus: Another herb used in TCM, Astragalus has been employed for centuries to balance the vital energy, or qi. Astragalus has been used to help maintain normal functions of the liver, lungs, kidney, spleen, stomach and heart. The beneficial properties of Astragalus support the immune system through its antioxidant action and energy-boosting potential, and by supporting production of white blood cells.
  • Vitamin C: The first scientifically recognized antioxidant, Vitamin C is the tried-and-true free radical scavenger we use to help support our immune system. Many research findings concur that Vitamin C plays a key role in supporting the direct activity of key white blood cells, and helping to support normal cells against damage, particularly damage caused by environmental toxins.
  • Vitamin E: The second most widely known and used antioxidant vitamin, this fat-soluble vitamin is essential for maintaining a strong immune system, and research has consistently demonstrated its vital role in supporting healthy, normal cellular activity.
  • Vitamin A: Another of the primary antioxidant vitamins, Vitamin A assists normal immune functions by maintaining white blood cell production.
  • Coenzyme Q10: Well known for its cardiovascular support, this natural compound is created and used by the body in normal cell respiration, helping cells use oxygen efficiently. CoQ10 is being studied in human research, and it has been found to support immune function in patients, as well as support the heart.
  • Selenium: This essential trace mineral produces antioxidant enzymes, which help prevent free radical damage to cells. Research suggests that selenium may help maintain normal cell functioning by protecting cell membranes. Selenium is also reported to help with normal cleansing processes.
  • N-acetylcysteine: Another potent antioxidant, NAC is one form of the amino acid Cysteine, and it is known for its ability to assist the body in removing highly toxic heavy metal residue from tissues, residue that increases the cell damaging activity of free radicals. NAC is one of the few antioxidant compounds that is able to penetrate and protect the cells’ mitochondria, where the main energy-producing components of cells are found. NAC is also known to support healthy liver function and healthy immune system response in the respiratory system.
  • Green Tea Leaf (decaffeinated): This powerful antioxidant has protective compounds called polyphenols that neutralize free radicals in the body. Human research with green tea has shown that it maintains normal cell functioning.

Each bottle contains 90 capsules containing a pleasantly flavored powder that is easy to administer.

This product was made in an FDA-approved facility using human-grade ingredients.

    Comments about Only Natural Pet Immune Strengthener:

    I adopted a 12 year old male Kitty with FIV. He had been a stray and was in pretty bad shape when someone took him to the Humane Society. They fixed him up and I brought him home. He had a continuous herpes condition in his eyes which caused his eyes to drain continuously and I was always washing his face. The shelter had started him on L-lysine which I continued for a few days while I was waiting for the Immune Strengthener to arrive. The bottle has 90 capsules and I break open one per day In His wet food which he LOVES! After about a month his eyes were intermediately better; he would sometimes go half a day without me having to wipe his eyes. And then gradually over the next two months his eyes have almost completely cleared up! Now I may have to wash his face once every couple of days. He used to squint a lot also with this condition and I felt that there was at least some discomfort if not pain and that has gone away as well! I will keep him on this Immune Strengthener for the rest of his life as I feel it's helping his compromised immune system get stronger.

    I will keep my dog on this product for life

    By Bridget

    Comments about Only Natural Pet Immune Strengthener:

    This is the first review I have ever written in regards to a purchase. I feel compelled to write and share my success, and I will write a review for the several other products I purchased from ONP as well. My 12 year old pug became deathly sick. She collapsed when tried to get up, wouldn't eat, throwing up, hardly could walk. Took her to the vet for blood work to determine her illness. Blood work came back with white cell count at 53,000, normal range is 6,000 - 15,000. Also, off the charts liver enzymes and bilirubin. Turns out she had pancreatitis which affected her liver do to its severity. I hospitalized immediately for 4 days, only for her white blood cells to increase to 65,000. I decided to take her home and stop all antibiotics and meds. After sleepless nights of research and educating myself with her conditions I decided the natural holistic approach. This immune strengthener has proven highly effective. After a few weeks she began to regain her strength and energy. And now she is 6 weeks in on this supplement, she is running and energy like a 7 year old. Finally decided to bring her back for blood work. Her white blood cell count is down from 65,000 to 20,000 in just under 6 weeks. Her vomiting and refusing food stopped - she begs for food again.
    I used this in conjunction with Liv-herb, bio-zyme, super milk thistle and pancreas booster. And began home cooking her a low fat organic diet. And all of her off the charts blood work came back with significant improvements. This product in addition to the rest of the products from only natural pet saved my dogs life. I will always do my own research and buy holistic natural remedies for my dog from now on.

    Great Product for My Dog Dealing with an Autoimmune Disease

    By Coal and Coon's Mom

    from Boulder, CO

    Verified Reviewer

    Comments about Only Natural Pet Immune Strengthener:

    I use this product for my 3 year old keeshond mix that was diagnosed with an autoimmune disease years back. It is successfully under control proudly without the use of toxic steroids. This product is wonderful as it helps support my dog's compromised immune system, helps her body keep normal inflammation levels and aids in cleaning up the toxic residues of the horrible steroids my poor dog once was on. This product is a great, natural, safe and effective supplement and I'm glad I found it for my dog. My dog is a brat with taking pills so I just sprinkle it on her food and she eats it no problem.

    Comments about Only Natural Pet Immune Strengthener:

    My 10 year old Australian shepherd takes this along with some other supplements to keep him young.
    Everyone comments on how great he looks for 10! I am sure this is helping so I gave some to a friend
    to give to their 10 year old lab/shepherd mix who has been sick with tumors. Time will tell but we are
    waiting and watching for some good results! Vitamin C in this is a very important addition as the older pets seem to lose their ability to make as much.

      As my cat is getting older, I wanted to strengthen her immune system. this is making her fur shinier and she is playing more. Seems to be working. I break open the capsule and dust her food, using one every 3 days.
      You can smell the mushrooms and she seems to like the taste

        Comments about Only Natural Pet Immune Strengthener:

        My nearly fourteen year old lab, had to have an eye removed due to a trauma to the eye. My vet also removed a small growth on her hind leg during surgery. The area where the growth was removed never properly healed. My vet used dissolvable stitches. (May have had something to do with not healing) My dog licked it so much, the area was down to raw skin. Another large lump grew and a few months later ruptured. It was a localized infection, which my vet did not catch. She was put on antibiotics and pain meds for two weeks. The lump did get smaller after antibiotics, but was still there. I took her to another vet for a second opinion, because the first vet wanted to do surgery again. The new vet gave me a combination antibiotic, anti-itch spray to be used three times a day, which stopped her from constantly licking the area. She told me if it doesn't get bigger or rupture again, everything should be okay.

        I started her on Immune strengthener three weeks ago and I am nearly done with the bottle. The lump has all but disappeared. The hair is finally starting to grow back from the original surgery site. She has more energy. She was really droopy for several months. She's not acting like a puppy, but the evidence is clear, the immune strengthener has really helped improve her general health. I finish the dosage Saturday. I'm going to switch her over to the Senior Canine Vitamins from this store. The senior vitamins have many ingredients that I believe will keep her on the right track. After reading reviews I see a lot of people keep their pets on the these for the long term. My dog is a pretty tough girl for her age, considering what she has been through the past several months.

        I used the capsules without opening them up and covered the caps with canned food. Note: my dog is not a picky eater. She will eat anything. If a capsule only had a light coating of canned she would eat it.

        She had no side effects.

                Comments about Only Natural Pet Immune Strengthener:

                We rescued a purebred Skye Terrier almost two years ago from a puppy mill and she's been through a slew of health issues in her 21 months of life. Living in an apartment makes it difficult to keep her 100% healthy since we don't know if everyone takes care of their dogs as well as we do. After ordering this and giving it to her, she's had only 1 soft stool but it was because she ate something she shouldn't have. From the very first day we put it in her food she had absolutely no adverse reactions to it and hasn't gotten sick, so my wife and I can only assume it's helping. We will continue to give it to her to keep her healthy; if nothing else, it gives us peace of mind.
