Rapid cell division for maximum immune defense: When the immune system responds to pathogens, immune cells (such as T lymphocytes and B cells) must divide millions of times within a few hours. Each individual cell division requires billions of new DNA and RNA building blocks. Immun & Cell + Nucleotides provides the body with the perfect synergy of 5 carefully selected nucleotides (including inosine) as well as high-dose vitamin C and vitamin B12, which have been shown to contribute to the normal function of the immune system and healthy cell division.**
Imagine your immune system as a special operations unit of the fire department when an infection first begins: As soon as pathogens invade, the alarm is sounded. To ward off the danger, the unit must grow from a small handful to a massive army within a few hours. To do this, the immune cells must divide rapidly and in the millions. For this biological feat, the body needs unimaginable amounts of building material— nucleotides. However, this is where our body’s biochemical bottleneck lies.
Immun & Cell + Nucleotides takes a completely different approach, based on the groundbreaking research of Dr. Peter Köppel: Through a highly sophisticated single-cell selection process of nucleotides using enzymatic hydrolysis and ion exchangers, we isolate nature’s five crucial building blocks: adenosine, guanosine, cytidine, uridine, and the cellular energy wonder inosine. We combine these five ultra-pure substances in a precise ratio modeled after the natural matrix of human breast milk. Nature has been using this system for millions of years as an evolutionary gold standard to build up the immune systems of newborns in record time. With Immun & Cell + Nucleotides , we are making this highly efficient building principle perfectly bioavailable to your immune system for the first time.
Traditional vitamins are important, but they’re just the workers. Nucleotides are the building blocks for the DNA and RNA of the immune cells themselves. During an infection or an allergic overreaction, the cellular system often breaks down because the building blocks needed for rapid cell division are missing. In Immun & Cell, we’ve combined five essential nucleotides with vitamin C and bioactive vitamin B12. This synergy has been shown to reduce the burden on the metabolism, accelerate cellular regeneration, and modulate the immune response so that even allergic reactions proceed more gently at the cellular level.**

Nucleotides are the basic building blocks of DNA and RNA. They are the alphabet your body uses to write genetic information, build new immune cells, and regenerate damaged tissue.
Each of your more than 50–70 trillion cells carries your entire genetic information in the form of DNA. This DNA is made up of just four building blocks—nucleotides. Together with RNA, the cell’s “instruction manual,” nucleotides control how proteins are built, how cells divide, and how tissue regenerates.
Immunology research is increasingly focusing on cellular health—that is, the question of how quickly and precisely the body can mobilize new immune cells in an emergency. Nucleotides are not a “stimulant” for an overreactive immune system. However, they are the natural building blocks without which the explosive cell division of T cells and leukocytes, as well as the repair of mucous membranes during infections or allergies, cannot take place.
Endogenous production, recycling, and nutrition are sufficient as long as the demand is moderate. However, in cases of acute infections, high allergen exposure (such as pollen), or chronic stress, the body’s own synthesis may be too slow to clone trillions of new cells in record time. That is precisely when Immun & Cell supplements the missing building blocks directly at the cellular level.
Each nucleotide performs a specific function in cellular structure. Immun & Cell combines all five—individually selected and in a highly pure form. The five nucleotides in Immun & Cell—AMP, CMP, GMP, IMP, and UMP—are precisely the building blocks that are recognized in European Food Regulation (EU) No. 609/2013 as a separate category of substances alongside vitamins, minerals, and amino acids.
Serves as a building block of RNA, as a precursor in energy metabolism, and as a signaling molecule. Provides the cell's energy currency.
Adenosine monophosphate
is a building block of RNA and a component of new cell membranes — essential for tissue regeneration.
Cytidine monophosphate
is a key building block for the formation of RNA, which is necessary for protein synthesis in cells.
Guanosine monophosphate
serves as a precursor for the formation of adenosine and guanosine nucleotides, which are important for cellular energy (ATP).
Inosine monophosphate
supports the regeneration of nerve fibers and the formation of cell membranes.
Uridine monophosphateVitamins and amino acids help balance the immune response. Before new cells are formed, the system must be properly regulated. High-quality vitamin C and B12 protect existing immune cells from oxidative stress and regulate histamine release. This creates a stable foundation that allows the immune system to function in a controlled manner, rather than overreacting indiscriminately to allergens (such as pollen or animal dander).
For the explosive proliferation of immune cells, the body needs immediate DNA/RNA building blocks. When viruses, bacteria, or allergens attack the system, the body must clone millions of new immune cells per second. Each individual cell division requires 3.2 billion nucleotides. Immun & Cell provides all five biologically active nucleotides in a perfectly defined, highly bioavailable formulation, ensuring that the immune system does not run out of building blocks at the critical moment.
Immune cells divide at record speed and build up a powerful wave of defense. T cells and leukocytes multiply without error, while damaged tissue and irritated mucous membranes are repaired at the same time. The faster and more smoothly this cell division can proceed, the more efficiently your body fights off infections and the more gently allergic reactions unfold at the cellular level.
Vitamins regulate the response. Nucleotides provide the building blocks. Only when the two work together do they produce the dual protective effect that takes effect directly at the cellular level. The first pillar—protection against free radicals—is ensured by the bioactive power of vitamins; Immun & Cell provides the second, crucial half of the equation for a rapid, intelligent immune response.
“In my holistic therapeutic practice, I work daily with people suffering from chronic fatigue, immune deficiencies, or severe allergic reactions. Vitamins alone often reach their limits in these cases because the stressed immune cells lack the actual building blocks needed for the rapid cell division required. With the product Immun & Cell + Nucleotides, the result is a faster, more precise immune response and a noticeably shorter recovery time for my patients.”**

In an emergency, your body responds more quickly and effectively to viruses and bacteria.
Thanks to balanced cell modulation, the excessive release of histamine triggered by pollen or animal dander is calmed.
The combination of vitamin B12 and cellular relief helps alleviate the typical fatigue that comes with a cold.
Take Immun & Cell capsules in the morning with a glass of water. The precisely dosed formula ensures an exact supply of all five nucleotides as well as bioactive vitamins.
The dosage can be increased over a 2-day period. At the first signs of a cold, an allergy, or an infection, the dosage can be increased over a 2-day period.
Cellular immunity acts as a daily shield. Especially before and during cold season or pollen season, consistency matters more than quantity—make Immun & Cell + Nucleotides a regular part of your routine.
Do not exceed the recommended daily dose. Not suitable for people with gout, a yeast allergy, those who have undergone organ transplants, or those taking immunosuppressive medications. Consult a doctor before use if you are pregnant, breastfeeding, or taking medication.
"The classic scenario: the younger child catches a cold—runny nose
, mild fever—and the older child "usually" catches the cold as well after 2
days. When the older one started
sneezing, she took 2 doses of Immun+Cell before bedtime, and lo and behold,
she didn’t have a cold the next day!
She then took another 2 Immun+Cell capsules that evening, and the
cold was completely gone. This is the first time a cold in its early stages has been nipped in the bud. Remarkable !”

Vitamin C is an essential cofactor and antioxidant that protects immune cells from free radicals. However, it does not provide the structural building blocks (nucleic acids) necessary for actual DNA replication during cell division. Only the combination of antioxidant protection (vitamin C), the activation of cell division (vitamin B12), and the appropriate cellular building blocks (5 individually selected nucleotides) provides comprehensive support at the cellular level.
The breast milk matrix is the ratio of nucleotides—perfected by nature—that infants absorb through breast milk to rapidly build up their still-immature immune systems and intestinal barriers. Dr. Peter Köppel has made this biological ratio available to adults. Single-cell selection ensures that the purine and pyrimidine bases are present in precisely this highly efficient ratio, which leads to demonstrably higher bioavailability in the small intestine.
Nucleotides support the immune system by providing the building blocks for rapid cell division (proliferation) of T and B lymphocytes. Since these immune cells are largely unable to produce nucleotides on their own (due to a lack of de novo synthesis), a deficiency during acute phases leads to a delayed immune response. Supplying individually selected nucleotides accelerates the production of new immune cells via the salvage pathway.
The product works on two levels: The bioactive vitamins C and B12 provide immediate, noticeable support for the nervous and immune systems and help reduce fatigue. The cellular effects of the nucleotides take effect as soon as the body enters a phase of increased demand—such as at the first signs of a cold or at the start of pollen season. For optimal protection, it is recommended to continuously replenish your body’s stores several weeks before the cold or allergy season begins.
Inosine is included in our Immune Mix because it acts as a universal and highly efficient precursor for the synthesis of adenosine and guanosine in human purine metabolism. It boosts the immune cells’ dynamic energy management by accelerating the regeneration of adenosine triphosphate (ATP). This conserves valuable energy for the immune cells, which they need to directly defend against toxins and pathogens.
Yes, due to the biological nature of nucleotides, there are clear exceptions. Since uric acid is produced during the breakdown of nucleotides, this product is not suitable for people with gout. Similarly, due to the manufacturing process, it should not be taken by individuals with a yeast allergy, after organ transplants (due to its immunomodulatory effect), or while taking immunosuppressants. If you are pregnant, breastfeeding, or have a chronic pre-existing condition, it is advisable to consult a doctor beforehand.
The perfect way to get your immune system ready for cold and allergy season.
