Fish contain protective compounds beyond DHA and EPA, such as secoiridoids, which may protect against oxidation.

“And his argument is that, of course, fish have much more than just DHA and EPA and things like that, so they have antioxidants, things like the secoiridoids and things like this, whether you find them in plants or animals that actually are protective, because you have to remember you're looking at something with multiple sites of desaturation so it's very sensitive to oxidation. And so you have to protect that, and you're absolutely right. Again, this idea that we had in the past that, you know, fish, hey, it's just as good just to get that oil out, it's not just as good.”
