I use cod liver oil as it's so cost effective. The only problem with it is the high vitamin A and D content. In summer i only take half the recomended dosage. And you'll always know if it's rancid as it's in liquid form.
Twinlab Dale Alexander Omega 3 Fish Oil. It is highly concentrated and economical. It tastes kinda funky, but you get used to it pretty quick. It is mint flavored.
