I appreciate and understand your cynicsm, but PLEASE PLEASE PLEASE read this as a starting point, and you may begin to appreciate why I keep parroting on about the importance of balancing the threes and sixes.
Taking an omega three supplement is not sufficient if you are at all convinced, several sources would suggest on top of balancing the threes and sixes getting 2-3 mg a day of DHA/EPA as a starting point from diet or supplements.
