Could a daily synbiotic soothe Alzheimer's behavior?
NCT ID NCT06948929
First seen Jun 26, 2026 · Last updated Jun 26, 2026
Summary
This pilot study is testing whether a daily synbiotic supplement called SCV09 can improve behavioral symptoms in people with Alzheimer's disease. The supplement contains probiotics, prebiotics, and vitamins thought to support the gut-brain connection. Thirty participants aged 60-85 with mild-to-moderate Alzheimer's will take the supplement for several weeks, and researchers will track changes in mood, behavior, and daily function.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- SCV09 (a synbiotic formula with probiotics, prebiotics, and vitamins)
- What this could lead to
- If it works, this could point toward a simple dietary supplement to help manage behavioral symptoms in Alzheimer's disease.
- What could go wrong
- This is a very small, early pilot study with no placebo group, so results may not be reliable. The supplement may not improve symptoms at all.
