Cod liver oil or fish oil, make sure it's safe and tested free of mercury and PCB's. Protects your brain cells.

B vitamins also helpful for depression or low moody days.

I've noticed a lot of people using lots of DMSA mention anxiety. Maybe there is a connection. I use it too but only once or twice a week, never more than two doses 50-75 mgs) in a row, rarely more than twice per week, just one dose now and then, when and if I hear the sound of mercury/heavy metal rushing through my head. The heavy whirring sound...

Cilantro, basil and garlic pesto never made me moody, quite the opposite but not sure that's for you at this point.
