About this study
Official title: Multicenter Interventional Real-world Study Evaluating the Impact of the Dietary Supplement GynMDD Administered as an add-on to Supportive Psychotherapy in Patients With Mild to Moderate Depression.
The goal of this clinical trial is to learn whether the dietary supplement GynMDD, when taken as an add-on to supportive psychotherapy, can improve symptoms of mild to moderate depression in adults aged 18 to 65. The main questions it aims to answer are:
Does adding GynMDD to supportive psychotherapy lead to a greater reduction in depressive symptoms (measured by the MADRS scale) compared with supportive psychotherapy plus placebo?
Read more
Does the supplement also improve digestive well-being and influence gut microbiota profiles over the course of treatment?
Researchers will compare patients receiving supportive psychotherapy + GynMDD to those receiving supportive psychotherapy + placebo to see if GynMDD provides additional benefits beyond standard care.
Participants will:
- Attend regular appointments with their general practitioner
- Complete one supportive psychotherapy session per week for 8 weeks
- Take a daily dose of GynMDD or placebo
- Complete weekly self-assessment questionnaires on mood, digestive symptoms, and any side effects via a mobile app
- Provide two stool samples (at the start and end of the study) for microbiota analysis
