What's actually in your fish oil tablets? Not much of any use at all.

Looks like un-oxidised Omega 3 fatty acids are a little harder to come by than just tacking a tablet from a jar.

...shocking news about what's really in that fish oil capsule a lot of you swallow every day. A US study which, as you'll discover, replicates findings in New Zealand and Australia, has found that it is far from what you think you are paying for. Preston Mason is a pharmacologist (that's someone who studies the action of drugs) at Brigham and Women's Hospital and Harvard Medical School in Boston. Preston Mason: It's a huge industry. We went to the local stores and started purchasing a number of very popular brands of these dietary supplements, brought them back to the lab, opened up the capsules and began to examine them for their content. And there were several interesting observations. One, the omega-3 or the desired part of the fish oil supplement only represented in many cases a third of the overall product, the other two-thirds being other fats, including significant levels of saturated fat. Norman Swan: Saturated fat? Where did that come from? Preston Mason: That is just the way it comes from the source, and many of the preparations, they do not remove these other fats, they just put it in as it's harvested. The other problem which is as serious is that we found that the omega-3 fatty acids themselves were generally oxidised… Norman Swan: Meaning they had interacted with oxygen, like rust, like biological rust. Preston Mason: Absolutely, so they are no longer effective. So we actually would test them. And because they were oxides they had no benefit, they were not able to have some of the biological activity that we associate with these important omega-3 fatty acids.
