If my fish oil oxidized, is there any point in taking it?

Pretty sure it's oxidized. It's extra fishy smelling, and causes me to have some nasty fish burps. I completely forgot to refrigerate them. I'm willing to deal with the nasty burps if they're still doing me any good. Are they still beneficial at this point?

I think that your nose knows best. If it smells bad, it's literally millions of years of evolution yelling "Don't Eat!" at you.

If your fish oil is really fishy it's probably rancid. I've had luck with Carlson brand.

You could also try Fermented fish oil/ cod liver oil by Greener pastures, which tastes horribly fishy but it's safely fermented rather than rancid. It's very expensive, though.

I asked a similar question a while ago http://paleohacks.com/questions/32354/is-carlson-cod-liver-oil-too-oxidized-to-be-worth-it#axzz1OEKVOhJ8

and someone showed me this chart which is how Carlson processes their fish oil to prevent oxidation. http://www.luckyvitamin.com/skins%5CSkin_1%5CBrochures/FAQaboutFishOils.pdf

Well I've been sick to my stomach (including vomiting) quite a bit over the last couple of weeks, and I now have it narrowed down to the fish oil supplements, for what it's worth, so I'd say no. I'll update if I get sick again without taking them, but so far, so good.

false you cannot smell if it is oxidized. If it has been molecularly destilled the stuff that begins to stink is no more present. This does yet not change that the O3s get oxidized...

in other words: with the cheap oils you can rely on your nose, with the expensive processed ones you have no idea what you are taking
