Read the detailed description

A double-blinded, randomised and placebo-controlled study will be conducted to assess the effect of 3 months of daily consumption of a postbiotic (inactivated lactic acid bacteria), Humiome® Post LB, on stress measured by the Depression Anxiety Stress Scale-21 (DASS-21) adjusted for baseline in study participants when compared to placebo.

The study will be in healthy subjects who are getting older (ageing population) and will measure factors such as stress, sleep, anxiety as well as gut microbiome. The intervention period will be 90 days, and study will include 236 subjects in two arms (active and placebo),

Questions about this trial

What is this clinical trial studying?

A study testing Humiome Post LB (Postbiotic) in people with Healthy Aging, run by dsm-firmenich Switzerland AG at 3 sites in 2 countries.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 8 inclusion and 16 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Where is the study taking place?

The record lists 3 sites in France, Germany. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

How can a doctor refer a patient or contact the research team?

Contact Liana Vismane, DR (+493040008122, lvismane@a-r.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Effect on stress (time frame: Timeframe - Day 0 (V2), and Day 90 (V4)). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 6 Nov 2026.
