Is this trial a fit for you?
✓Likely a good fit
Adults aged 18 and older in Spain who are either regular kefir consumers or willing to start consuming Activia Kefir and complete online questionnaires.
✕Probably not a fit
Individuals not consuming kefir or not providing online questionnaire data may not benefit from the study findings.

What this trial studies
This observational study will collect real-world data from adults who either regularly consume or start consuming Activia Kefir. Participants will complete questionnaires about digestive wellbeing, general wellbeing, and related factors, and provide stool samples to explore potential microbiome associations. The study will analyze consumer perceptions and any microbiome signals associated with kefir consumption in Spain. Data will come from self-reported outcomes and biological samples collected across designated Spanish sites. No experimental intervention beyond regular product use is required.
Why it matters
Potential benefit: If successful, findings could help understand how Activia Kefir relates to digestive comfort and quality of life in real-world use.
How similar studies have gone: Observational work in real-world nutrition often identifies associations between dairy probiotic products and digestive well‑being, though mechanisms remain exploratory in this context.

Show full inclusion / exclusion criteria
Inclusion Criteria: 1. Males and females aged 18 years and older at the time of screening; 2. Willingness to consume Activia Kefir and complete the requested questionnaires; 3. Living in the designated locations in Spain, able to read and write in Spanish; 4. Have a personal electronic device compatible and connectable to internet (i.e., computer, laptop, smartphone) to fill the questionnaires; 5. Signed informed consent. Exclusion Criteria: 1. People that currently participate in another study with (dairy) investigational or marketed products; 2. Severely immunocompromised individuals (e.g., post-transplant, advanced HIV/AIDS, undergoing chemotherapy); 3. Individuals with known allergies or intolerances to product ingredients. For lactose maldigestion, kefir may improve tolerance, so individuals who are aware of their condition and still wish to participate can be included.
