It's unclear if it's bioavailable from those sources at all. There's two forms ALA and DHA; the first is found from nuts and the second from algae. The fish get it from the algae.
IIRC there is some evidence that ALA is only bioavailable for women and not for men, but I don't remember if that's reliable.
- DoreenMichele 3y agoI had heard that flax seed may not be bioavailable. Walnuts are my go to as the only vegetarian source I understand to have substantial amounts of bioavailable omega 3. Would love to get a clearer idea of how much I really need and how much produce I consume may be defraying that number.
- derbOac 3y agoIt's difficult to find EPA or DHA from vegetarian sources (other than algal oil), although ALA is easier (e.g., walnuts, flax, chia). Camelina oil is another good source of ALA if you can find human-grade versions of it. I thought it was nice as a sort of alternative to olive oil raw (like served with bread, or maybe tossed in cold salads), although it had its own flavor (sort of a grassy flax-like flavor), and is impossible to find now it seems. It wasn't something I would probably use a lot of but had a solid niche. At one point there was some interest in transgenic camelina oil because it was easily converted into varieties expressing EPA and DHA. For example: https://www.nature.com/articles/srep08104 https://www.nature.com/articles/srep08104 I've never seen that sold anywhere though.
