What does Immunokun provide for your cat?

Immunokun nutritional supplement boosts your cat's defenses. This supplement is ideal for cats with low immunity, such as kittens or senior animals, obese animals, or those under stressful conditions, furry friends in vaccination periods, or those suffering from infections.

What is Immunokun for in your cat?

It's the go-to supplement for combating and preventing infections. It can be administered to animals of any age! Thanks to its active ingredients stimulating the immune system, this dietary supplement maximizes immune system function by boosting your cat's defenses, ensuring robust health.

How do its active ingredients work?


Beta-glucans are Pathogen Associated Molecular Patterns (PAMPs) molecules that act as modifiers of the immune response. They activate local macrophages and dendritic cells to positively regulate MHC class II and increase the secretion of cytokines (TNF-α, IL-2, IL-10, and IL-12), allowing them to efficiently present antigens to T lymphocytes and initiate an effective immune response. Beta-glucans stimulate a new concept called trained immunity or innate immune memory, which allows macrophages, monocytes, and natural killer cells to show a greater responsiveness when they encounter pathogens again, both at the digestive and systemic levels.

Lysine has indirect antiviral properties against feline herpesvirus type 1 (FHV-1). Cells infected with FHV-1 require arginine in the medium for viral replication. Lysine is not necessary for viral growth, but when present, it has a partially inhibitory effect on FHV-1 replication due to competitive inhibition of arginine. Supplementation with lysine in the early phase of infection reduces viral replication, resulting in less severe conjunctivitis and respiratory symptoms.

L-glutamic acid

Precursor of glutamine, considered a conditionally essential amino acid and a key nutrient for the proper functioning of the immune system. Glutamine is the preferred energy source for immune cells, and providing higher amounts of this essential nutrient enhances their functioning.

Enterococcus faecium

Encapsulated probiotic (technology ensuring the stability of the bacteria during the manufacturing and storage period of the product). Enterococcus faecium modifies the immune response through two mechanisms. 1: Indirectly by balancing the intestinal microbiota. Competition for nutrients, adhesion sites, and the production of antimicrobial substances (short-chain fatty acids, defensins, etc.) inhibit the proliferation of pathogenic bacteria while promoting the development of beneficial bacteria; 2: Direct effect on both innate and acquired immune response to pathogens at local and systemic levels. Probiotics induce maturation of dendritic cells and macrophages (increasing their phagocytic activity and antigen presentation efficiency to T lymphocytes), promote cytokine production (TNF-α and IL-6), stimulate the cellular activity of natural killer cells, and enhance vaccination response (increased production of IgG and IgA).

They increase the secretion of IgA in the intestine, stimulating the most important humoral immune factor of the intestinal mucosa. They inhibit the adherence, colonization, and penetration of bacteria and toxins, increase mucus secretion, and prevent the uptake of food antigens. In this regard, the increase of IgA at the intestinal level represents greater local immune capacity and greater protection against pathogen invasion.

Prebiotic component, which indicates that it resists digestion and reaches the colon intact where it serves as a source of energy, thereby promoting the proliferation of beneficial bacteria (Lactobacillus spp, Bacteroides spp, and Bifidobacterium spp), which inhibit the growth of pathogenic bacteria exclusively through competition. Additionally, as a result of its fermentation, it increases the release of short-chain fatty acids (acetate, propionate, lactate, and butyrate) into the intestinal lumen, reducing the presence of pathogenic bacteria (E. coli and C. perfringens), thanks to the reduction of colonic pH.

Vitamin E

Immune cells contain particularly high concentrations of vitamin E to protect themselves from oxidative damage related to their high metabolic activity and the high content of polyunsaturated fatty acids in their plasma membrane. Vitamin E improves the integrity of the cell membrane and positively modulates signaling events in T lymphocytes. Additionally, indirectly, vitamin E protects T cell function by reducing the production of T cell suppressive factors such as PGE2 produced by macrophages.

Vitamin C

It is the most potent reducing agent available to cells. Vitamin C regenerates the enzyme glutathione, neutralizes free radicals both intracellularly and extracellularly, and protects against the inactivation of proteins mediated by free radicals associated with the oxidative burst of neutrophils.

It acts as a cofactor of glutathione peroxidase, an antioxidant enzyme that protects tissues against oxidative stress by catalyzing the reduction of hydrogen peroxide and organic hydroperoxides and by regenerating vitamin E.

Zinc increases the activity of antioxidant enzymes such as glutathione peroxidase and is a cofactor of the enzyme superoxide dismutase, which catalyzes the conversion of superoxide radicals into H2O2, which are less oxidative. Zinc deficiency is a cause of dysfunction in almost all classes of immune cells, as well as being related to thymus involution.

To whom and for what purpose?

  • Immunokun prevents the occurrence of infections and improves the health of healthy animals with weakened defenses, such as kittens from weaning to 6 months of age, senior animals (around 7 or 8 years old), overweight cats, animals under conditions of chronic stress, or lactating females.
  • In cats positive for infectious diseases such as feline flu (feline herpesvirus 1 rhinotracheitis and feline calicivirus), feline leukemia, feline immunodeficiency, ehrlichiosis, etc., Immunokun reduces symptoms and slows the progression of these infections, improving the quality of life for your cat.
  • In case of other diseases that involve immunosuppression such as Cushing's syndrome or genetic disorders like the Birman cat abnormal granulation syndrome, Immunokun prevents the occurrence of secondary infections, improving the health of your furry friend.
  • During any vaccination, Immunokun enhances the immune system response to vaccination, making it more effective and providing better protection for your cat.


The use of IMMUNOKUN is not recommended in the following cases:

  • Patients with allergies (whether food allergies, environmental allergies, flea bite allergies, drug allergies, etc.)
  • Patients with acute or chronic systemic inflammatory conditions such as arthritis, dermatitis, enteritis, hepatitis, pancreatitis, etc.
  • Autoimmune diseases such as Addison's disease, pemphigus, lupus erythematosus, rheumatoid arthritis, glomerulonephritis, immune-mediated meningoencephalitis, myositis, etc.
  • Animals undergoing chemotherapy treatment or concurrent use with pro-oxidant drugs, as the antioxidant effect of Immunokun could reduce their effectiveness.
  • Patients with epilepsy.

How is it administered?

Daily recommendation to be added on top of the food. This dose can be divided into different servings throughout the day:

Tablespoons* Package Duration
0,5 1,5 months

*9,5 g per tablespoon. 
The spoon is included in the package.

For very small kittens, start by administering half of the recommended dose (1/4 of a spoonful per day).

Immunokun for cats can be administered together with any type of diet (dry food, homemade or commercial cooked food, BARF or dehydrated food). Additionally, it can be administered chronically without the need for any resting period between bottles.

How long should I administer it?

  • Healthy animals with low defenses (kittens, senior animals, obese, lactating females, etc.): Administer half of the recommended daily dose as a preventive treatment.
  • Cats positive for infectious diseases: Administration is recommended for at least 1 month and should be maintained as long as the symptoms persist.
  • Other diseases that involve immunosuppression: Administration is recommended for at least 1 month and should be maintained as long as the symptoms persist.
  • During any vaccination: 5 days before vaccination, on the day of vaccination, and for the following 7 days.
