2 g/d of omega-3 acid ethyl esters (930 mg of eicosapentaenoic acid [EPA] and 750 mg of docosahexaenoic acid [DHA]) = 1680g omega 3 about 5 or 6 daily of the omega 3 you bought.
I can't get the full text so I can't see if these people were in hospital or not but I guess these were at home.
I guess also they were eating their "normal" SAD diet.
As we know
High Omega-6 Diet Lowers Omega-3 Status, but Low Omega-6 Diet Preserves
it is a fact that higher omega 6 intake displaces omega 3 although a higher intake of omega 3 does in the short term help improve plasma and stroke, surgery, accident, survival a significant reduction in omega 6 enhances that action.
IDEALLY our omega 3 ~ omega 6 ratio would be 1~1 at worst it should be no more than 1~4
current UK average is 1~10
current USA average 1~20
So you can see why Dr Davis is using much higher amounts of omega 3 to try to make a significant difference to the ratio.
Stephan on the other hand thinks the main emphasis should be on
REDUCING THE OMEGA 6 side of the see saw
I don't know if any of you have listened to the talks at the omega 3 conference here

Really set up for the military but still interesting.
The Hibbeln session was particularly interesting in regards to depression.
Omega Fatty Acids and Aggression, Suicide and Psychiatric Distress
CAPT Joseph R. Hibbeln, M.D.
At some point in the day someone asked how long it takes to change brain omega 3 DHA status and the answer was 2.5yrs to change 50%.
So given a background where omega 3 is added in a situation where it's being overwhelmed (neutralised, displaced) by omega 6, too little is being used and only 10 weeks was allowed, is anyone surprised by the result.
