Anecdotal datapoint: vitamin D provokes depression for me. Take 5000IU in the morning and an episode is guaranteed in the next evening. Episode consists of pretty bad mood and "inability to think" for the lack of better words. And it builds up of course. After about a month of 10000IU daily I was on a brink of suicide. Unfortunately I did no tests whatsoever. I've had zero psychiatric issues before but I do have a fistful of medical conditions.
