Your link to the Herald Tribune and Mercola both recommend DHA (and omega-3). It is seriously one of the greatest things you can take, hands down. Nordic Natural is an expensive brand, and buying at Whole Foods is even more expensive (try Amazon, and a cheaper, but quality brand is Carlson's). It is hard to tell sometimes when you go off a supplement the true effects because your high DHA levels can take a while to be used up, and even then the body has processes to try and scavenge or breakdown molecules in other areas to make up for it. It is much more efficient and beneficial to provide the needed stuff in a useable form.
Why? I'd certainly take everything he says cum grano salis, but it's still better than pretty much any other general health information site on the web.
