I did a check on the selenium, and supplements are not good, can overdose on it. Get it from fish, nuts,meat, egg yolks, mushrooms,grains, onions, and garlic. A normal daily amout is 108mcg. 350mcg is a safe maximum, according to my health book. 1000mct can cause hair loss and fragile nails. Just to let anyone know who might be reading this. Thanks! We eat lots of these good foods, so this is probably not his problem. I think the depression is closer.
