About this trial
This clinical trial investigates the effects of Vitamin B6 supplementation on neural inhibition using electroencephalography (EEG), in relation to depression and anxiety symptoms in participants from the general population with a relatively high level of symptoms at baseline. Researchers will compare a placebo group to high-dose Vitamin B6 to test the hypothesis that Vitamin B6 moves the excitation/inhibition balance towards inhibition.
