What this trial studies

This pilot interventional study tests the synbiotic formula MQU10 in adults reporting mild to moderate depressive symptoms. Eligible participants (age ≥18) with PHQ‑9 scores of 5–14 will take MQU10 and complete self‑report mood and well‑being questionnaires while being monitored for safety. The protocol excludes people with bipolar disorder, psychosis, recent suicide attempts, active substance dependence, recent major GI surgery, or certain serious medical conditions. The study is conducted at GenieBiome Limited and Healthymind Centre in Hong Kong and will collect symptom and safety data to inform whether larger trials are warranted.

Who should consider this trial

Good fit: Adults aged 18 or older with mild to moderate depressive symptoms (PHQ‑9 score 5–14) who can read, consent, complete questionnaires, and are not on recently changed psychotropic medications are ideal candidates.

Not a fit: People with severe depression, bipolar disorder, psychotic illnesses, active substance dependence, recent suicide attempts, or major uncontrolled medical conditions are unlikely to be eligible or to benefit from this pilot.

Why it matters

Potential benefit: If successful, MQU10 could offer a well‑tolerated supplement option that helps reduce depressive symptoms and improve quality of life for some patients.

How similar studies have performed: Emerging clinical research on probiotics and synbiotics shows some promise for mood improvement via the gut–brain axis, but results have been mixed and larger definitive trials are limited.
