I've recently purchased a couple of different kinds of Omega 3 supplements, but haven't yet added them to my regimen. The one I think I'll like better came from Nature's Sunshine (I got a distributorship through a local holistic doctor, but I've never sold the product - I only purchase it for personal use). At any rate, the reason why I think I'll like Nature's Sunshine's Omega 3 better is because it includes lemon extract, which is supposed to suppress the "fishy" aftertaste that I guess other Omega 3 supplements have to contend with.
Speaking of Omega 3's: I went to my local Wild Oats store today and was going to buy some catfish (I know...not the best source of Omega 3, but I just love catfish). They didn't have any, but they recommended a fish from Vietnam called Basa. They actually gave me a free filet to try. I came home, baked it for lunch with a spiced cornmeal coating, and it was superb! If I hadn't known it wasn't catfish, I would have sworn it was! So, if you like catfish, give Basa a try!
