 Fish, mackerel, sardines, trout, and then also supplements. But it's very hard to get all your omega-3s in from just fish alone. I mean, you'd have to be downing fish every night. But that's not good because there's a lot of mercury in those fish that could also lead to health complications. But you can also find ALA omega-3s and flax seeds, chia seeds, and walnuts. So you don't have to just get them from fish alone.
