Fish oil oxidizes at room temperature, and even quicker as soon as it hits your stomach, causing oxidative damage instead of helping your body. After a lot of research, I'm switching to Arctic Ruby Oil instead of fish oil.  Arctic Ruby Oil contains a lot of astaxanthin to keep it from oxidizing, and will last 3 years in sealed containers kept below 25 degrees C; it was exposed to oxygen for 190 hours without showing any sign of oxidative damage, is much better than fish oil, and works better than Krill oil.

It's important to have these oils each day to support your cell membranes, heart, arteries, brain, joints, and to optimize your health:
(See the links, because these are just short excerpts. It's best to have a 1:1 omega-6 to omega-3 ratio like our healthier hunter-gatherer ancestors did, instead of the 20:1 and even as much as 40:1 ratio that most people have today [mostly from processed foods that contain hydrogenated or rancid processed corn, soybean, canola, safflower, sunflower, "vegetable" and other oils], but it's important not to get too much of omega-6 and omega-3 also, since they can oxidize and excesses can deplete your antioxidants and harm your body, so it's important to decrease your omega-6 -- not to just increase your omega-3.)

Rudi Moerck on Fish Oil  When to Never EVER Use It

...Remember, You Can't Substitute with Plant-Based Omega-3…

    Plant-based omega-3 sources like flax, hemp, chia and perilla seeds are high in ALA – the third type of omega-3 fat. ALA is an absolutely essential fatty acid. It is converted in small quantities to EPA and DHA in your body.

    Dr. Moerck recommends men to consume a minimum of 1.6 grams a day; women 1.2 grams daily. However, you do not want to consume more than 5 grams a day.

    This means that if you eat just 2 tablespoons of chia seeds, you've actually exceeded your daily dose.

    Still, I do not recommend using these plant-based sources as a substitute for animal-based omega-3 (DHA/EPA), or as your only source of omega-3.

    Why?

    Because the conversion of ALA to the far more essential EPA and DHA is typically severely impaired by inhibition of delta 6 desaturase. This is an enzyme that is necessary to produce the longer chain EPA and DHA from ALA.

    Elevated insulin levels impair this enzyme, and over 80 percent of Americans have elevated insulin levels. So from that perspective alone, plant-based omega-3 simply will not work well for most people.

    There are also studies that indicate ALA from flaxseed might actually increase your risk of cancer… In addition, flax seed oil is also used in industrial manufacturing, such as paint, so it can be trickier to ensure that the flax seed you get is actually fit for human consumption, since paint manufacturing does not have to worry about damaging the omega-3...

    For these reasons, Dr. Moerck and I agree that flax seed oil is best avoided.

    If you want to use flax seed, buy organic, whole seeds, then grind them just before consuming them to ensure freshness. This is also important because, just like fish oil, plant-based omega-3 fats are also highly perishable. For this reason you want to avoid buying pre-ground seeds, because you can be guaranteed that they have been damaged by the time you even get them home from the store.

    Personally, I regularly include ALA omega-3 plant based foods, like flax and hemp in my diet, but I always use them in combination with animal based omega-3 fats.

    For more information about omega-3 fats, both plant- and animal based, please listen to the interview in its entirety, or read through the transcript.

Differences Between Omega-3 Fats From Plants and Marine Animals

...Dosage Recommendations

According to Hoem, fatty fish is your best source of long-chained omega-3 fats. However, remember that all fish do NOT contain these fats. Tilapia, for example, contains no EPA or DHA. Ideally, the fish needs to be harvested from cold water, as this is what triggers the production of these fats in the fish.

    "There are particular types of fish that are fatty and fish that live in cold waters. You need to inform yourself with regards if your particular type of fish contains enough of the long-chain omega-3s or not. But I would guess in a fatty fish, typically I would say two to three servings a week would be enough.

    With regards to krill oil, again depending on who you are and what you do, I certainly would not recommend less than 1 gram. I take 2 grams a day. By that I am well supplemented. I'm between eight and 10 in my omega-3 index. Also, I would say ... I wouldn't be afraid of taking too much. I hardly think, within the normal ranges we're seeing, that we would be able to do that. I have still not yet seen an overdose of fish."

Ground flaxseeds are a useful addition to most peoples' diets. The unfortunate problem though with using them for most people is that when one has elevated insulin levels, the delta six desaturase enzyme is severely inhibited.

This enzyme is responsible for converting the alpha linolenic acid (ALA) in flax to longer chain fats (like EPA and DHA) and it is easy to develop an excess of ALA in one's system, which is counterproductive.

Who has elevated insulin levels?

Most Americans, as just about anyone who is overweight (60% of the US population) has excess insulin, as do most of those with high cholesterol, high blood pressure or type 2 diabetes.

So the flax should be used sparingly and probably alternated with other ground grains, like sunflower, sesame and pumpkin, which will help to balance the omega six and omega three ratios.

Pumpkin seeds have other fats in them which are likely to be particularly beneficial for prostate health.

The seeds should be freshly ground in a coffee grinder and I prefer to have them in my freshly produced vegetable juice pulp. Most people who juice throw away the pulp, but I am convinced it is a valuable source of nutrients and should be consumed like a porridge while drinking your fresh vegetable juice.

Drink your juice and eat your pulp.

I don't recommend the use of flaxseed oil however, particularly because of its instability. Five years ago, I used to recommend it to nearly all my patients and I noticed the majority of them could not tolerate it.

This is despite the fact that they were using two of the best brands of flax oil in the country (Omega Flow and Barleans). I came to the conclusion that the nausea they were experiencing was a giant clue from their body and subsequently concluded that most people do not do well with flaxseed oil, which is why I no longer recommend it...
