100 g of flax seeds said to be containing approx. "22.8 g" omega-3 ("mostly ALA"). The body needs to convert the ALA to EPA (conversion rate: "5-10%") and DHA (conversion rate: "2-5%"). (sorry, don't have the sources but it is found quickly by searching for those numbers)
My questions are (1) how much of that flax seed ALA is acual EPA and DHA already, Wikipedia says only "mostly ALA", if any, and (2) how correct is my calculation of estimated EPA/DHA from the flax seeds's ALA amount?:
My calculation so far: Let's say the "22.8 g" are 90% ALA, so:
EPA at 10% conversion: 2,052 g.
DHA at 5% conversion: 1,026 g.
The flax seeds are grounded very well for maximum absorption, and the question is, how much of that is absorbed compared to an flax oil form. Also, did I forget anything else regarding actual absorbed amount of fatty acids form that 100 g flax seeds? Or just: Is my calculation close enough?
(I know the conversion of ALA to EPA/DHA by the body can suffer with age and/or how nutrified the body is, so other EPA/DHA sources, like from fish, may be advised, but this is a different topic)
