Does anyone know if the total essential fatty acids need to be 1000 mg to be effective or if the various components, EPA and DHA, each or either need to be 1000 mg. I ask because my girls currently take Coromega orange squeeze (one packet daily) and the breakdown is this:

2,000 mg fish oil
650 mg Omega-3
350 EPA
230 DHA

my girls are between 30-40 lbs so I am wondering if this is meeting the threshold. They also eat DHA enhanced peanutbutter and egs, and their regular vitamin has a small amount of DHA.

I have read that you need to have a higher EPA to DHA ratio. Does anyone have more information about determining the best ratio and the best amounts of EPA and DHA... I may also post this as a stand alone question. Thanks.
