The intestine is the “second brain” of the body. Over 70% of the immune system resides in the gut, and the microbiome (a collection of microorganisms) affects mood, weight, allergies, and even the risk of chronic diseases. Probiotics are a proven way to support the microbiome and restore it after disturbances.
What are probiotics
Probiotics are living microorganisms that, when taken in sufficient quantities, have a beneficial effect on human health (WHO definition). The most studied probiotics belong to the genera Lactobacillus and Bifidobacterium.
Prebiotics are dietary fibers (inulin, FOS) that feed beneficial bacteria. Probiotics + prebiotics = synbiotics — the most effective combination for the microbiome.
When probiotics are needed
Main situations where probiotics have been proven to be effective:
- After antibiotics — antibiotics destroy not only pathogens, but also beneficial flora
- Irritable bowel syndrome (IBS) — bloating, pain, unstable stool
- Traveler’s diarrhea — Lactobacillus rhamnosus reduces duration by 1-2 days
- Frequent colds – strengthening of immunity through restoration of the microbiome
- Vaginal dysbiosis — Lactobacillus reuteri and L. rhamnosus
- Allergy and atopic dermatitis – especially in children
- Inflammatory bowel diseases — UC, Crohn’s disease (as an adjunct to treatment)
How to choose the right probiotic
1. Number of CFU (colony-forming units)
More is not always better. For prevention, 5–10 billion CFU per day is sufficient, for treatment of dysbiosis — 20–50 billion CFU. It is important that these CFUs are alive at the time of expiration, not at the time of production.
2. Variety of strains
Multistrain probiotics are more effective than monocultures. Optimal combination: several species of Lactobacillus + several species of Bifidobacterium.
3. Resistance to stomach acid
The probiotic must reach the intestines alive, overcoming the acidic environment of the stomach (pH 1.5–3.5). Look for capsules with an acid-resistant coating or use lyophilized (freeze-dried) forms.
4. Storage conditions
Most probiotics need to be stored in the refrigerator. But modern stabilized forms (NSP Bifidophilus) can be stored at room temperature.
NSP Probiotics: Bifidophilus Flora Force
Bifidophilus Flora Force from Nature’s Sunshine contains 4 strains of bacteria: Lactobacillus acidophilus, L. casei, L. rhamnosus and Bifidobacterium longum — a total of 4 billion CFU per capsule with guaranteed activity until the end of the shelf life.
Additionally contains fructooligosaccharides (FOS) as a prebiotic base – nutrition for probiotic cultures.
When and how to take probiotics
- Time of administration: on an empty stomach or 30 minutes before a meal – less stomach acid
- After antibiotics: start 2 hours after taking the antibiotic, continue 2-4 weeks after the end of the course
- Prevention: 1-3 months with breaks
- Storage: follow the conditions on the package
Conclusion
Probiotics are an effective and safe way to support intestinal health and strengthen immunity. The key to the effect is the correct selection of strains and a sufficient dose of CFU. After antibiotics, probiotics are a must — they shorten the restoration of the microbiome from 6 months to 2–4 weeks.
