Good post McBain. Flax oil is full of omega 3 oils, but jif you need DHA and EPA(for the brain and heart) then fish oil is a good choice also. I take two tablespoons of flax and two tablespoons of cod liver oil(flavored, of course) a day. Udo Erasmus, who is supposed to be the expert on oils has had patients take up to 10 tblespoons a day for weight loss. There is a product you can get at most health food stores called "Udos Perfected oil blend" which is supposed to be the perfect blend of omega 3's and omega 6's. Great stuff and tastes a little better than plain flax. Great info can be found at his website. Just go to any search engine and type in "Udo Erasmus".
BTW-flax oil is reportd to be good for preventing breast cancer and many othe types of cancer. It is also good for preventing prostate problems. Also-after about a month your skin will be as soft and smooth as a baby's butt!
