NCT ID NCT07469462
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether taking high-dose vitamin B6 can reduce symptoms of anxiety and depression by changing brain activity. Researchers will measure brain waves with EEG and track mood changes in 44 adults who have mild to moderate symptoms. Participants will take either vitamin B6 or a placebo for a set period, and the results will show if this simple supplement can help calm the brain.
