Tips for taking probiotics
Choosing the right product is crucial. Pay attention to:
-
The exact name of the strain (e.g. Lactobacillus rhamnosus GG , not just "Lactobacillus rhamnosus")
-
Adequate dosage (at least 1–10 billion CFU/day)
-
Duration of intake (often several weeks required)
-
Storage: Refrigeration required for some products

Quality and study evidence of the manufacturer
Multi-strain products can be helpful if several symptoms occur simultaneously – it is worth taking a critical look at the composition.
