Probiotics: their importance for health, types and rules of administration

Digestive problems, frequent colds, allergic reactions and even chronic fatigue can be the result of an imbalance in the intestinal microflora. The human body is inhabited by billions of bacteria that form microbiome – a complex system that affects all aspects of health. Probiotics play a key role in maintaining a balance between beneficial and pathogenic microorganisms.
What are probiotics and why are they needed?
Probiotics are live microorganisms that help restore the balance of intestinal microflora. They help absorb nutrients, stimulate the immune system, prevent inflammation, and protect the body from pathogenic bacteria.
According to gastroenterologist Oleksandr Vlasenko, probiotics are important not only for the health of the digestive system, but also for overall well-being. An imbalance of microflora can cause a decrease in immunity, the development of allergic reactions, and increased fatigue.
Functions of probiotics:
- Restoration of intestinal microflora after antibiotic therapy
- Supporting normal digestion
- Protection of the intestinal mucosa
- Improving the absorption of vitamins and minerals
- Immune system support
- Reducing the risk of intestinal infections
Types of probiotics
Different groups of probiotic bacteria have specific functions that help the body in different aspects of health.
| Probiotics group | Examples of bacteria | Main action |
|---|---|---|
| Lactobacillus | L. acidophilus, L. rhamnosus, L. casei | Improves digestion, protects the intestinal mucosa |
| Bifidobacteria (Bifidobacterium) | B. bifidum, B. longum, B. lactis | Strengthens immunity, regulates metabolism |
| Saccharomyces | S. boulardii | Prevent antibiotic-associated diarrhea |
| Spore-forming bacteria | Bacillus coagulans | Improves resistance to pathogenic bacteria |
Immunologist Dr. Svetlana Nikitina explains that the intestinal microbiome plays a central role in regulating immune responses. Regular intake of probiotics can reduce the risk of developing infections and allergic diseases.
How probiotics work
When probiotics enter the intestines:
- Create favorable conditions for the growth of beneficial bacteria
- Inhibits the reproduction of pathogenic microorganisms
- Produce enzymes that help absorb nutrients
- Promotes the synthesis of vitamins B and K
- Improve intestinal barrier function
Gastroenterologist Maryna Savchenko emphasizes that probiotics have a positive effect not only on digestion, but also on the nervous system. It has been proven that some strains of probiotic bacteria can reduce stress levels and improve emotional state.
Products containing probiotics
In addition to pharmaceutical supplements, probiotics can be obtained from natural fermented foods.
| Product | What probiotics does it contain? |
|---|---|
| Kefir | Lactobacteria, bifidobacteria |
| Yogurt | Lactobacillus acidophilus, Bifidobacterium |
| Sauerkraut | Lactic acid bacteria |
| Kimchi | Lactobacteria |
| Miso | Lactobacillus casei |
| Kombucha | Yeast and bacteria |
Nutritionist Olga Dmitrieva recommends including probiotic products in your daily diet. This helps to gradually restore the microflora and improve your overall well-being.
How to take probiotics correctly
For probiotics to work as effectively as possible, certain rules should be followed.
- Take probiotics on an empty stomach or before meals
- Combine probiotics with prebiotics (fiber, inulin) for better effect
- Follow a course of treatment from 10 days to several months, depending on the need
- Choose appropriate strains for specific problems
Gastroenterologist Oleksiy Kovalenko advises including probiotics in the treatment regimen when taking antibiotics, but taking them at an interval of 2-3 hours after the antibiotic to avoid neutralizing beneficial bacteria.
