Probiotics are living microorganisms that, when taken regularly, can produce health-promoting effects. However, not all probiotics are the same – their effectiveness depends heavily on the strain, dosage, and the specific health condition. In this article, you'll learn which probiotics are truly among the best, which specific strains help with which conditions, and how to find the right probiotic for your needs.
Why is choosing the right probiotic so important?
Probiotics usually have strain- and indication-specific effects. While a specific strain of bacteria can promote gut health, others are specifically effective for skin problems, allergies, or mental health. Therefore, it's essential not to just buy any product, but to specifically select the strain that's scientifically recommended for the specific problem.
Probiotic strains and their main applications
1. Lactobacillus paracasei LP-33 – Probiotic for allergies
The Lactobacillus paracasei LP-33 strain has made a name for itself in allergy research. This strain exhibits immunomodulatory properties, particularly in hay fever, house dust mite allergies, and other allergic reactions. Studies show that LP-33 supports the immune system by improving the balance between different immune cells and reducing the production of allergy-triggering inflammatory messengers.
In addition to LP-33 , Bifidobacterium longum GMNL-133 has also been shown to be helpful in treating allergies. This strain can regulate the immune response and has anti-inflammatory effects, which contributes to symptom relief.
2. Streptococcus salivarius M18 – For oral health
The oral flora is often underestimated, but it plays a crucial role in the health of teeth and gums. Streptococcus salivarius M18 is a specially researched probiotic strain that contributes to the reduction of bad breath, tooth decay, and gingivitis. By producing natural antibacterial substances, M18 can displace pathogenic germs in the mouth, thus reducing the risk of dental problems.
3. Lactobacillus helveticus Rosell®-52 and Bifidobacterium longum Rosell®-175 – For mental health and stress
The gut-brain axis is a fascinating field of research that shows how gut bacteria can influence our mood, anxiety, and stress levels. Lactobacillus helveticus Rosell®-52 and Bifidobacterium longum Rosell®-175 play a central role here. Studies show that these strains promote the production of neurotransmitters, reduce stress hormones, and thus contribute to improved mental health.
4. Lactobacillus rhamnosus GG (LGG) – classic remedy for diarrhea and immune system
The Lactobacillus rhamnosus GG strain is one of the most researched probiotics in the world. LGG exhibits a protective effect, particularly in diarrheal diseases such as traveler's diarrhea or antibiotic-associated diarrhea. LGG also strengthens the immune system and promotes the barrier function of the intestinal mucosa.
5. Bifidobacterium infantis 35624 – Irritable bowel syndrome and digestion
Patients with irritable bowel syndrome (IBS) often benefit from Bifidobacterium infantis 35624. This strain helps improve the balance of intestinal flora, reduce inflammation, and relieve symptoms such as bloating, abdominal pain, and diarrhea.
6. Lactobacillus acidophilus – General intestinal health
Lactobacillus acidophilus is a versatile strain often used in combination supplements. It supports digestion, improves nutrient absorption, and helps restore healthy intestinal flora after antibiotic treatment.
Table: Overview of the best probiotic strains & indications
| Probiotic strain | Main indication | Effect & Special Features |
|---|---|---|
| Lactobacillus paracasei LP-33 | Allergies | Immune modulation, relief of hay fever & house dust allergy, atopic dermatitis |
| Bifidobacterium longum GMNL-133 | Allergies | Anti-inflammatory, supports immune response |
| Streptococcus salivarius M18 | Oral health | Reduces caries, gingivitis, combats bad breath |
| Lactobacillus helveticus Rosell®-52 | Mental health, stress | Improves mood, reduces stress hormones |
| Bifidobacterium longum Rosell®-175 | Mental health, stress | Supports neurotransmitter production, calms the nervous system |
| Lactobacillus rhamnosus GG (LGG) | Diarrhea, immune system | Protects against diarrhea, strengthens intestinal barrier |
| Bifidobacterium infantis 35624 | Irritable bowel syndrome (IBS) | Relieves flatulence, abdominal pain, regulates intestinal flora |
| Lactobacillus acidophilus | General intestinal health | Supports digestion, common combination probiotic |
How do I choose the best probiotic for me?
1. Determine your health goals
Before purchasing a probiotic, you should be clear about the health issue you want to address. The choice of strains depends on your individual situation—whether it's allergies, digestive issues, oral health, or mental well-being.
2. Pay attention to the scientific evidence
Not every probiotic strain is equally well researched. Look for products with strains that have been confirmed by clinical studies. Also pay attention to the exact name of the strain (e.g., Lactobacillus paracasei LP-33), as the effect is strain-specific.
3. Dosage and survivability
For probiotics to be effective, they must reach the intestine alive and in sufficient quantities. Check the number of colony-forming units (CFU) contained in each dose. A minimum of 1 to 10 billion CFU is appropriate for many indications.
4. Quality and storage
Quality products guarantee the viability of the bacteria until consumption. Some probiotics require refrigeration, others are heat-stable. Read the storage instructions carefully.
Conclusion: Probiotics are as individual as you are
The best probiotics depend on your health situation. Those who specifically select the right combination of effective strains will benefit significantly more than with a single "all-rounder." Lactobacillus paracasei LP-33 and GMNL-133 help with allergies, M18 is the ace for oral flora, while L. helveticus Rosell®-52 and B. longum Rosell®-175 boost your mental health. Classic strains such as LGG and Bifidobacterium infantis complement the range for digestion and the immune system.
