Why your pet needs Only Natural Pet Immune Strengthener

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

This formula supplies a wide range of antioxidant ingredients to foster the maximum reduction of free radical damage to cells. We also included 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

  • 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 anti-microbial and 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, anti-viral and antibacterial action. 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, from the common cold to the most serious of autoimmune and organ dysfunctions. 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 enhancing the infection-fighting action of white blood cells.
  • Coenzyme Q10: Well known for its cardio-protective 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 functioning in patients with severe autoimmune issues, as well as support the heart from damage that may be caused by some toxic residues that result from their required treatment regimens.
  • 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, which may help minimize severity of side effects found with some traditional disease treatment protocols.
  • 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 in a wide variety of the most serious autoimmune disorders.

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

    Comments about Only Natural Pet Immune Strengthener:

    I open a capsule and shake the powder over canned food once daily. My rescue cat has a compromised immune response and had lost most of her teeth to gum and bone infections. Since starting a regime of this product and Omega-3 oil, the tooth loss slowed and now, after 1 year, seems to have stopped entirely. I think the product has helped and plan to continue to use it.

      Comments about Only Natural Pet Immune Strengthener:

      I bought these immune support vitamins for my recently adopted 6 year old cat who has FIV. I break the pill into half and mix into his tuna twice a day. He eats it no problem and seems to like the taste. I noticed that his energy levels have certainly improved and his eyes have a healthy glow since administering for 2 plus weeks. I love that these vitamins contain mushrooms known for their immune strengthening support. Only Natural Pet is a great site and company. I simply typed in FIV in the site's search feature and it displayed these vitamins as a result which was right on. I will always be a cat owner and will always shop from Only Natural Pet!

      Comments about Only Natural Pet Immune Strengthener:

      Other than the shipping taking about 2 weeks it has a smell that our dog notices even as its mixed in his food. He is taken back by it but still eats it. Also, haven't noticed a significant change in his skin conditions and overall health considering we started mixing coconut oil with his food n appling to his coat prior to receiving this supplement which helped immediatly. May need to wait a few months for supplemental to work in order for final results.

          My dog (Shepard/husky mix) has responded well to this supplement. Her coat is fuller and shinier now and her itching has been reduced tremendously in the 4 months I have been giving her this supplement.
          I highly recommend this if your dog has scratching issues.

            I started using these about 3 or 4 months ago for my allergy Plagued lab. I wish i had taken before and after photos, but i guess i never expected to see such drastic results. Prior to using this, his tummy was red and covered in scabs/sores he was constantly itching and scratching and was extremely sensitive to ear infections. I was worried at first about getting him to take it as he is an EXTREMELY picky eater and HATES taking pills even with food. I love that these are capsules so i just break them open and pour over a wet/dry food mixture for dinner (he actually seems to like the taste of it shockingly). Within a few weeks we started to see his skin clearing up and hair growing back on his tummy. after 4 years of struggling with his allergies i feel like i have finally found something that WORKS!

              My cat has had a sinus infection(for years) that has been relieved only temporarily by antibiotics. I wanted to try something more natural. I have tried colloidal silver and olive leaf, but those had no effect upon his condition(sneezing, runny eyes, thick yellow mucus from nostrils), until I tried "Only Natural Pet Immune Strengthener by Only Natural Pet". His sinus infection is not completely gone, but his breathing has greatly improved and I no longer see a thick yellow discharge from his nostrils and sneezing is at a minimal. I will continue to use this product because I am seeing results. I give him one capsule per day in his food. I will try increasing the dose to 2 per day in his food.

                      I'll point out up front that this review is for both the Pet Immune Strengthener, and the Respiratory Support. It's for both, since we started our sick cat on both of these, so it is impossible for us to know which one did the trick. But THEY DID WORK AMAZINGLY WELL!

                      Our 13 year old girl (cat) had been suffering from respiratory problems for several months. We had been to the vet, and they prescribed antibiotics, saying that it was either a respiratory infection, or perhaps toxoplasmosis or a brain tumor, since she was also rather unstable on her feet, was low energy, and according to the vet, one pupil was bigger than the other. Jumping up on my lap was something that became difficult or impossible for her to do.

                      We put her through the first round of antibiotics for two weeks. She got pretty much all better, but then after a short while, relapsed, and started wheezing again. She was throwing up here and there, but that was to be expected from the antibiotics. So the vet put her on 3 weeks of antibiotics. We did that (while also giving her the Only Natural Pet GI Support), and she got mostly better again. But then she started to relapse.

                      The doctor wanted to do another round of antibiotics for a longer period of time. We were a bit hesitant, but started the course. After just a couple of days, our cat got very ill-- throwing up, and not eating anything for a whole day. I said that was enough of that, stopped the antibiotics, and researched good respiratory/immune formulas that got good reviews.

                      That's when I found Only Natural Pet products. I ordered that day, and within a week or perhaps 10 days, we started giving her both the Immune Strengthener and the Respiratory Support. Very shortly thereafter, she started getting her energy back, her lungs cleared up, and she was back to being her old, playful, frisky self. An amazing relief! A couple of months later, she's still on both products and totally back to normal-- jumping up and down on tables, chasing toys, etc.

                      Again, I don't know which product did this, but it worth a million dollars to have her back to being her old self. Thanks ONP!!!
