K9 INUExtra® dog immune supplement – Natural daily immune support

K9 INUExtra® dog immune supplement is a premium, multi-functional immune formula for dogs, and it provides daily, targeted support. It combines high-potency medicinal mushrooms, high-IgG colostrum, natural brewer’s yeast, microencapsulated omega-3 fish oil, Curcumin C3, BioPerine, PS-70 phosphatidylserine, zinc picolinate, and natural vitamin E.

Because these ingredients work together on several levels, they actively support immune function, reduce inflammation, improve gut balance, and promote faster recovery. Each component adds a clear benefit, and the synergy between them strengthens the overall effect.

The strength of K9 INUExtra® lies in synergy: every ingredient enhances the others, and together they help maintain immune balance, calm inflammation, and support natural regeneration. Because of this, the supplement is especially valuable for senior dogs, allergic dogs, immunocompromised dogs, and dogs receiving cancer treatment.

Medicinal mushrooms – Intelligent immune support

K9 INUExtra® dog immune supplement is built on the Organic Immune Assist™ mushroom complex, which contains six species: Reishi, Turkey Tail, Almond mushroom, Cordyceps (sinensis and militaris), Shiitake, and Maitake. Because this complex provides 66% polysaccharides and 60% beta-glucans, the mushrooms can work together more efficiently, and they consistently strengthen natural immune defenses.

In addition, they help the body respond better to stress, infection, and inflammation, so dogs receive broader and more reliable immune support.

Research indicates that beta-glucans can enhance natural immune activity and support cellular defense in dogs with cancer, allergies, or weakened immunity.

Colostrum – Natural protection and regeneration

Premium German colostrum provides 20% IgG and 68% protein, and it supplies bioactive compounds that strengthen immune function, improve digestive comfort, and support tissue repair. It can also help calm allergy-related reactions, because it promotes healthier immune balance. Dogs that are recovering from surgery or going through chemotherapy often benefit from this support the most.

Brewer’s yeast – Internal support for resilience

High-quality German brewer’s yeast is naturally rich in B-vitamins, essential amino acids, and 23.8% beta-glucans. It supports digestion, gut microbiome balance, and nutrient absorption. It is especially helpful for weak, picky, or recovering dogs, including those on antibiotics or oncology treatment.

Omega-3, Curcumin C3, BioPerine, vitamin E, PS-70 and zinc – Cellular protection and regeneration

Microencapsulated omega-3 provides stable EPA + DHA levels for inflammation balance, heart health, and nervous system support. Curcumin C3 works more effectively together with BioPerine, which boosts absorption. Natural vitamin E protects cells from oxidative stress, while PS-70 phosphatidylserine supports cognitive function and stress resilience. Zinc picolinate plays an essential role in cell repair, immune balance, and healthy skin.

Together, these active ingredients provide deep, cellular-level support for senior dogs and dogs affected by cancer or chronic inflammation.

    Ovaj proizvod naručio/la sam već nekoliko puta. Kod mog bullterijera dijagnosticiran je rak 1. stupnja, a naš veterinar također je preporučio da uzima ovaj proizvod. Mnogi su u grupi za pse oboljele od tumora također pisali da je ovo jedan od najboljih proizvoda za tu svrhu. Ja sam zadovoljan/na, nije jeftin, ali je odličan proizvod. Koristimo ga naizmjenično s K9 Immunity kapsulama.

    Al mio cane è stato diagnosticato un tumore osseo che purtroppo non si può operare. Stiamo facendo di tutto per sostenere il suo sistema immunitario. Questo prodotto è fantastico, siamo già al terzo pacchetto. Ha buon umore, appetito e sembra felice – ed è questa la cosa più importante!

  3. Rosalinda (verified owner)

    Abbiamo iniziato a usare la polvere K9 InuExtra dopo che l’ecografia della nostra cagnolina di quasi 15 anni ha mostrato delle “macchie scure”. In quel momento, il veterinario ci ha detto che anche nel migliore dei casi ci sarebbero rimasti solo due mesi con Lola. Nessuna terapia ci è stata consigliata, per via delle (presunte) metastasi.

    Ne avevo sentito parlare bene e, visto che non c’erano molte alternative, abbiamo deciso di provare. Contro ogni previsione, Lola ha vissuto altri dieci mesi sereni con noi, e l’abbiamo salutata poco prima del suo sedicesimo compleanno.

    Sono profondamente grata a K9-doghealth.com per questo prodotto e per il tempo in più che abbiamo potuto passare con la nostra piccola. Lo consiglio davvero di cuore a chiunque si trovi in una situazione simile.

    Mein 8-jähriger Labrador Benny wurde mit einem Tumor diagnostiziert. Unser Tierarzt meinte, dass man ihn zwar operieren kann, aber die kleinen Metastasen leider nicht behandeln kann. Die Prognose war nicht gut, aber er hat mir geraten, das Immunsystem zu stärken.

    Ich habe im Internet nach Möglichkeiten gesucht und bin auf K9 InuExtra gestoßen. Ich habe es gleich bestellt und Benny angefangen, es täglich zu geben. Beim Kontrolltermin nach einem Monat meinte der Tierarzt, dass sich Bennys Zustand überraschend verbessert hat.

    Ich bin wirklich froh, dass ich dieses Produkt gefunden habe. Ich würde es auf jeden Fall weiterempfehlen. Vor allem für Hunde mit so einer Diagnose.

    Thomas, Bennys Besitzer

    Už kupujeme 4. balenie. Náš 9-ročný, 18-kilový kríženec má lymfóm. Veterinár na pravidelných kontrolách ani nechápe, prečo je náš pes v tak dobrej kondícii. Dostáva len toto. VEĽKÁ VĎAKA!

    Onze hond Boef, een kruising met spaniël van 6 jaar, had al jarenlang last van terugkerende oorontstekingen en huidproblemen. Soms waren zijn oren rood en gevoelig, andere keren had hij uitslag op zijn buik of dijen, en hij krabde zich voortdurend. Verschillende dierenartsen dachten dat het waarschijnlijk om een auto-immuunreactie ging, maar we kregen nooit een duidelijke diagnose. We hebben van alles geprobeerd: oordruppels met steroïden, zalven, hypoallergeen voer, antibiotica… Alles hielp maar even, en dan begon het weer van voren af aan.

    Het ergste was toen hij geen zin meer had om te spelen, lusteloos werd en bijna niet meer at. Toen ben ik echt gaan zoeken naar iets dat structureel kon helpen. Zo kwam ik terecht bij K9 INUExtra. In het begin was ik sceptisch, maar omdat het een natuurlijk supplement is dat het immuunsysteem ondersteunt, dacht ik: baat het niet, dan schaadt het niet.

    Na ongeveer drie weken merkte ik de eerste veranderingen. Hij krabde zijn oren niet meer, zijn huid zag er rustig en gezond uit, en hij begon weer met smaak te eten. Nu, drie maanden later, zie ik dat hij veel stabieler en energieker is en dat de klachten niet zijn teruggekomen. Hij krijgt het elke dag over zijn voer gestrooid en eet het zonder problemen op. We hebben geen enkele bijwerking gemerkt.

    Bij de laatste controle was de dierenarts ook verrast. Hij zei dat Boef er erg goed uitzag en dat zijn toestand opvallend stabiel was. Hij gaf zelf ook toe dat bij chronische ontstekingen vaak alleen ondersteuning van het immuunsysteem echt verschil kan maken.

    Ik ben ontzettend blij dat ik dit product heb gevonden. Ik raad het van harte aan aan iedereen met een hond die kampt met terugkerende klachten. Bij ons heeft het eindelijk rust gebracht. Boef is gelukkig, en wij ook.

    Anne, het baasje van Boef

    In early 2025, my 10-year-old male Kurzhaar’s mild limp began to worsen. Initial attempts at treatment by the vets were aimed at treating symptoms of arthritis and joint inflammation, but were unsuccessful. In May 2025, he had an x-ray taken, which showed significant thinning of the bone in the paw in question, as well as a bone malformation. The vet was over 99% convinced that it is osteosarcoma and immediately suggested a biopsy and amputation. The blood test results were excellent and apart from the limp, the dog seemed healthy. The news and the thought of the little time we had left together scared me a lot, but my intuition told me that he could do it without surgery and heavy chemotherapy. I looked for information about the diagnosis and came across K9 products. Initially, I ordered K9 INUExtra® and every day I observed slight improvements. Then the dog started taking K9 Immunity™, again a significant improvement and a return of strength to the dog, who, together with the hot summer weather, was having difficulty moving. Without interrupting the intake of K9 supplements, we also tried K9 Immunity Plus™. Now at the end of August 2025, the dog is active and full of energy again, with an excellent appetite and desire for walks. The swelling began to reduce slightly and he shows no signs of pain or suffering. The dog does not take any medications, only nutritional supplements for bones and joints. Huge thanks to the company – manufacturer, as well as the distributors. I would also like to add that I try to provide him with complete relaxation at home, a healthy diet, and that we also practice Reiki and energy psychology. Never lose hope, listen to your Veterinarian, respect the diagnosis and try to understand what our pets’ bodies want to tell us. Don’t get me wrong, my father was a veterinarian and somehow I’m sure that if he were here he would have chosen the alternative way without going all out with surgery or radiation. I have medical records that demonstrate the problem. Good luck to everyone.
