"Scientifically tested bacterial strains"
Institut AllergoSan has published peer-reviewed research on W-series strains; the gut-brain axis rationale is scientifically grounded.

"Improves IBS symptom severity"
Multi-strain Lactobacillus/Bifidobacterium blends have moderate clinical evidence for IBS symptom reduction.
Examine.com: Probiotics and IBS meta-analysis -
"Improves memory and cognition"
PubMed has no large RCTs showing these 9 specific strains improve cognition in healthy adults.
Internal: strain-level PubMed literature review -
"7.5 billion CFU supports gut-brain axis"
7.5B CFU split 9 ways averages 833M per strain — below the 1-10B CFU per strain used in most clinical trials.
Consumer advice
- • If you're specifically interested in gut-brain axis support, this is a credible product from a reputable Austrian manufacturer (Institut AllergoSan) with some strain-specific research behind it. However, before buying:.
- • Check if the specific strains (W-series) have published human trials for stress/mood — some do, some don't.
- • Compare to Seed DS-01 (~$50/month) or Garden of Life Dr. Formulated Mood+ (~$35) which have similar strain diversity at lower cost.
- • The subscription lock-in requires 2 billing cycles before cancellation — factor that in.
