the reason for the omega 3 content being lower in udo's oil is due to the impact that omega 3 and 6 fatty acids have on the prostaglandins derived from them. too much of one or the other will result in an imbalance between the series 1 and 2 prostaglandins. many assume that our diet is high enough in omega 6's, so we need a higher content of omega 3's like that found in flax. however, if you're on a strict diet and most of your fat is coming from flax, then you may not be getting enough omega 6's, depending where the rest of the fat comes from other than flax. this is where udo's choice can help. not to mention that udo's oil has some monosaturates in it, which are also very healthy and should not be neglected in your diet. so, as someone already mentioned, the ratio's found in udo's oil are the ratio considered optimal, although, depending on what other types of fat you eat, it may or may not be a better choice than flax oil.
