My whole family takes it (except me, I am a veggie head) They use non- mercury fish and are one the only brands that pass of pharmaceutical standards. They are 3-partied tested and have "no detected levels of metals, dioxins, or PCBs."
They are more expensive, but you know you are getting quality. My DH gets them on the web, but my mom gets them at Whole Foods
I had been buying it at the grocery store for $10 a bottle, but I think I'll get at the place linked above now! I take it in a shot glass with some orange juice.
I take Andrew Weil's Omega-3/Fish Oil capsules, also well-tested and mercury-free. I appreciate that there's no fishy aftertaste. Amazon has the best price on them, and you can do an automatic shipment plan with them.
