Lithium supplements maybe? There are over-the-counter supplements available. Prescription lithium has proven uses for some mental treatments. I read some positive things about areas with naturally occurring lithium in drinking water. As far as elements go, it is the first solid element at terrestrial conditions, so one might expect it to be a trace nutrient for organisms living in terrestrial conditions.

I'll research this a bit and give it a try. Thank you
