Working in the fish oil industry, oxidation of fish oil is very low for pharmaceutical grade. Stability trials (5-7 years) show low oxidation or degradation of product. If you buy fish oil, buy the best you can, pharmaceutical grade and the best advice I have heard from nutritionist/sports science is to immediately store your omegas/supplements in the freezer. The benefits of omegas have been clearly documented in scientific journals. Supplements is to supplement deficiencies in your eating plan.
If oxydation is very low, then it is all the more concerning that they still produce worse outcome long-term [cf. Ray Peat's "The Great Fish Oil Experiment"]. The only conclusion it leads to is that chronic PUFA intake, even from fish, is harmful.
Chicken today is totally disgusting and gives me gut rot, I stopped eating it around 2 years ago. Chickens in the wild would eat insects and worms, not grains and seeds
Thanks again to Dr Bikman for the elucidation of oxidation and peroxidation. I’ve bandied those two around interchangeably for a while. Erroneously fifty percent of the time I might add…Further, I recently read in a blog accompanying a grass fed meat sales purveyor email- possibly US Wellness Meats, a person was discussing current research data supporting the notion of omega 3 supplementation being healthful and empirically supported. However, actually eating salmon was superior. I’ll see if I can find that- it really put the argument about the two issues to rest.
PUFAs are obviously not bad, at least not inherently. We need them for basic functioning. DHA is an essential fat, after all, and it can be converted into EPA that is also necessary. But on an ancestral whole foods diet, many traditional populations got sufficient PUFAs without eating much or any fatty cold water fish. The body doesn't require high levels of omega-3s, as long as levels of omega-6s are lower. But the more physically active we are the more we burn through our omega-3s. And studies do show that some of the seeming health problems blamed on saturated fats are actually mediated by omega-3 deficiency. So, omega-3s are obviously healthy. It's just there is no particular need to supplement them on a healthy diet and no particularly reason to obsess over constantly eating fish.
Seed oils are all absolutely devoid of nutrient, except for vitamin E, naturally present to avoid oxydation. Fun fact: if you don't eat PUFA you don't need vitamin E (and vitamin A also acts as antioxidant agent anyway).
There aren't any pure Omega-3 extracts as I understand it. It's all fat extracts with no ability to separate EPA DHA completely, if that was what you were suggesting, I may have misunderstood
"Essential fatty acid deficiency" is a meme. Thousands of peaters worldwide should be having terrible symptoms -- but nothing is happening. The best way to improve omega-3 concentration in the blood is to abandon omega-6 (linoleic acid) entirely -- that's what we see in the Masaii studies, they have high n-3 content in the blood while they have practically no n-3 or n-6 sources. Even wild fatty fishes aren't even that fatty -- much less than their farmed cousins. Dietary animal n-3s are rare, their overconsumption is harmful. We had practically no linoleic acid intake before 1950. Trendy health advices can sound good but I'd rather trust long-term historical tendencies.

Exactly. Beef and seafood are the way to go.

It’s the plant and seed PUFAs, not the fish.
There might not be a need but I think we'll see that a higher intake of EPA and DHA will result in a direct drop in inflammatory responses.
The Vitamin A in cod liver oil isn't an issue. It's actually a good thing.

You are what you eat...
So I eat humans.
Most if not all omega 3 fish oil supplements always contain vitamin e as a "preservative".

"I don't know."
Imagine hearing your doctor say that. 👍
Brains need fat! Yes
😎👌👍🖖✌😁
