iMunobiom+®

Targeted probiotics for the whole family, featuring a single strain with a precisely described mechanism of action on the immune system—tested in over 35 clinical studies involving hundreds of children and adults.

iMunobiom+® is not vitamin C or a random multivitamin. It is a targeted probiotic designed for the whole family — built on one of the few probiotic strains with a precisely described mechanism of action on immunity. Free from lactose, GMO and synthetic additives. Capsule contents can be mixed into a drink. Take every day for at least 3 months.

iMunobiom+® is built on the concept of targeted probiotics created by iProbio co-founder MVDr. Alojz Bomba, DrSc. He established the only gnotobiology laboratory in Slovakia and founded the world's largest international probiotic conference — attended annually by scientists from more than 80 countries. iProbio directly participated in a large European vitamin D study, which formed the basis for selecting the 800 IU dose.

No compromises — free from lactose, histamine, GMO, glyphosate and synthetic preservatives
Lacticaseibacillus rhamnosus CRL 1505
35+ studies, described mechanism of action
Study on 300 children: reduces the frequency of respiratory and intestinal infections

Vitamin D3 — 800 IU
Plant-based source from lichen, suitable for vegans
The 800 IU dose was determined based on the largest European study (30 institutions, 18 countries)
Most of the European population is deficient — especially in autumn and winter
Contributes to the normal function of the immune system
Beta-glucans — 450 mg
Long chain, high bioavailability
Stimulate immune cells in the gut — trigger both specific and non-specific immune responses
Act as nutrition for the microbiome — feed beneficial bacteria
Strong antioxidant properties and support for immune cell growth

How does the gut microbiome benefit immune health?

The whole family including children
Clinically tested in children and adults. Suitable from age 3.
Frequent respiratory infections
Recurring colds, tonsillitis, bronchitis — the immune system needs targeted support.
Gut infections and diarrhoea
A diverse gut microbiome contributes to reducing the incidence of intestinal infections and diarrhea in both children and adults.

Autumn and winter — illness season
Preventive care for the gut microbiome before flu season.
Recovery after illness
After overcoming an infection or a course of antibiotics, it helps restore immune balance.
Weakened immunity in seniors
As we age, the gut microbiome naturally changes and becomes less resilient, making regular support important.

iMunobiom+® is not intended for children under 3, pregnant or breastfeeding women.

Scientific Evidence
Is Clear

The science of the microbiome is still in its early stages, and the scientific community is gradually uncovering its power. Even today, we know that the microbiome helps to:

  • Break down complex carbohydrates
  • Produce vitamins and minerals
  • Protect against harmful bacteria
  • Strengthen the immune system
  • Eliminate toxins

How does it work?

Your microbiome deserves the best care. The ideal is a balance between beneficial and harmful bacteria.

And this is where we come in!

Beneficial bacteria:

  • reach the digestive system in full strength,
  • survive the harsh environment of the stomach,
  • thrive and act in the intestines where they are needed,
  • serve as nourishment for existing beneficial bacteria and support their growth.
