How Does Krill Oil Stack Up Against Fish Oil?


Salmon Fish Oil Pills - Omega 3

Fish oil has become the most popular supplement in America — and for a good reason. Hundreds of scientific studies have demonstrated that the omega-3 fats it contains are extremely effective at protecting the heart and brain.[1,2]

They’re so effective, in fact, that even the mainstream medical establishment now stands behind it. In addition, a mountain of research has shown that omega-3s are also critical for mood balance, immune strength, supple joints, sharp vision, and youthful-looking skin.[3-7] The list of benefits simply goes on and on.

But as amazing as the benefits of fish oil are, researchers are learning more and more about a new source of omega-3s that they claim may be much more absorbable than fish oil and have unique antioxidant properties that provide additional health benefits. But is this just the latest omega-3 fad or a true scientific breakthrough?

Are You Critically Deficient in Omega-3s?

Every cell in your body requires omega-3s to function properly. Yet according to many experts, nearly all Americans are critically deficient.[8] When you lack omega-3s, you’re vulnerable to a wide range of health problems, including unexplained joint discomfort, mood swings, cognitive decline, vision loss, premature skin aging and cardiovascular issues.

However when you replenish your omega-3 levels, you’ll begin to notice amazing improvements in your health. But as emerging research is beginning to reveal, not all omega-3 supplements are created equal.

The Dangers of Low-Quality Fish Oil Supplements

There’s big money in fish oil and unfortunately, many supplement manufacturers looking to capitalize on fish oil’s popularity try to pass off worthless pills that contain pathetically low levels of omega-3s. What’s worse, these pills are often filled with toxins like mercury and PCBs. Of course, there are also some potent, high quality fish oil supplements that have been molecularly distilled for purity.

In recent lab tests, Consumer Reports found that 1 in 3 fish oil supplements fell short of claims made on their labels.[9] Some of these pills even contained rancid, oxidized or heavily polluted oil. Sadly, the problems with inconsistent fish oil quality are only getting worse, as the oceans become increasingly polluted.

A New Omega-3 Source That Renders Fish Oil Obsolete

You may have heard about a new omega-3 supplement called krill oil that certain experts, such as Dr. Oz, claim is healthier and more powerful than fish oil. Krill oil is made from krill, which are tiny pink shrimp-like crustaceans that are abundant in the waters surrounding Antarctica. Well, I’ve spent enough time in the natural health industry to know that not every trendy new supplement is worth its salt, so I set out to investigate the claims about this new discovery.

What I found out was that, while fish oil may have certain benefits over krill — the primary one being that it’s been much more extensively researched and tested long-term — krill oil may be superior to fish oil as a source of omega-3s in several ways. Here’s a summary:

Potency: Krill oil contains extremely high levels of the same important omega-3 fatty acids, EPA and DHA that fish oil provides. But unlike fish oil, krill oil also contains brain-protecting omega-3 compounds called phospholipids AND the potent antioxidant astaxanthin.[10] This combination is unique to krill oil.

Absorption: The omega-3s found in krill oil have a chemical structure that makes them easier for your body to absorb than the omega-3s found in fish oil.[11-13] This means you get more DHA and EPA in every serving.

Purity and Safety: Krill is harvested from the pristine icy blue waters of Antarctica, one of the cleanest marine environments in the world. Krill is also low on the food chain, so it doesn’t accumulate the toxins that fish does. As Dr. Oz put it when he featured krill oil on his TV show, taking krill oil is like “cutting out the middleman.”

So What Can Krill Oil Do for You?

Here are some of the clinically researched benefits:

1) Reduce Dangerous Inflammatory Markers by 30%

Unfortunately, the standard American diet is high in unhealthy fats, which can promote inflammation and damage cells throughout your body.[14] Inflammation is thought to be a major culprit in heart disease and brain aging, and is often responsible for various “mystery symptoms,” such as joint problems, fatigue, seasonal discomfort and dry skin.

Research shows that omega-3s found in krill oil can neutralize these unhealthy oils, keeping joint discomfort and soreness at bay. In addition, krill oil has been shown to be particularly effective at combating joint pain and inflammation.[15] One landmark clinical study showed that after just 14 days of krill oil supplementation, inflammation markers dropped 30%, while they rose by 32% in the placebo group.[16] In all my years in the natural health industry, I’ve never seen any supplement reduce these markers so quickly and efficiently.

2) Harmonize Your Cholesterol Ratios and Protect Your Heart

For a healthy cardiovascular system, you need strong, pliable blood vessels, and maintaining balanced levels of LDL (bad) and HDL (good) cholesterol is vital to keeping your blood vessels healthy. The trouble starts when LDL cholesterol oxidizes, building up inside your blood vessels and arteries, causing them to harden.

It turns out that there is perhaps no substance on earth more effective than krill oil at balancing LDL and HDL. In fact, one clinical study showed that just one-third of the amount of krill oil is up to 10 times more effective than other omega-3 sources at balancing cholesterol. For example, those taking krill oil had their LDL cholesterol reduced by as much as 32% versus 5% for fish oil, and their HDL cholesterol levels improved by up to 43% versus 4% for fish oil. In another head-to-head study, krill oil was shown to balance triglycerides by up to 28%, compared to just 3% with fish oil.[17]

3) Nourish, Protect and Supercharge Your Brain

Earlier, I mentioned that krill is rich in a type of healthy fat not found in fish oil, called phospholipids. When you nourish your brain with phospholipids, you’re giving it the fuel it needs to function optimally.[18,19] You’ll experience better moods, more alertness, improved focus and concentration and fewer “senior moments.”

A recent quality of life survey conducted on people taking either krill oil or fish oil revealed that those taking krill oil experienced a 48% improvement in mental health, compared to only a 15% improvement for fish oil.[20] Krill oil has also been shown to be extremely effective at combatting mood imbalances associated with premenstrual syndrome in women.[21]

Astaxanthin: Krill Oil’s Antioxidant Edge

In addition to its miraculous omega-3 benefits, krill oil is also incredibly rich in the antioxidant astaxanthin, the natural carotenoid pigment that gives krill, as well as salmon and flamingos, their rosy hues. Astaxanthin,which is thought to be one of the most powerful antioxidants every discovered, has been hailed for its anti-aging properties. It’s been shown to help prevent wrinkles, blemishes and dryness, and even reverse years of skin damage.[22]

Astaxanthin is unique in that, unlike many antioxidants, it can cross the blood-brain barrier to protect your brain and nervous system and the blood-retinal barrier to protect your eyes.[23,24] Astaxanthin has also been shown to enhance immunity, strength and endurance, making it easier to recover from exercise.[25,26]

As an added bonus, astaxanthin acts as natural preservative for the krill oil, preventing oxidation and rancidity, giving it a longer shelf life, as well as eliminating any possible “fishy” aftertaste that can happen with some fish oil supplements.

Try Krill Oil for Yourself

If you currently take a fish oil supplement, should you toss it out and immediately switch over to krill oil? Well that depends on personal preference and experience. As I mentioned earlier, fish oil is well studied and has many known health benefits, so long as you are taking a high quality supplement that has the right amounts of omega-3s and doesn’t contain any toxins, you should be safe. However, the initial scientific data on krill oil is very promising and the fact that you have to take less of it each day is very appealing to many people.

The only way to really know whether you should switch from fish oil to krill oil is to take it and see how it affects your body. You can certainly also take the two concurrently — that’s what I’ve been doing.

The Best Krill Oil Supplement for Your Money

There are lots of krill oil supplements out there, but sadly, many of them are junk made by companies try to take advantage of a new trend. So how do you know what getting a high quality supplement? The krill oil supplement I personally take is called OceanPure®.

    As always another well written piece.
    My only knock against krilloil, as is WHOLE FOODS who will not sell oit nationally is…
    Krill is an extremely important link in the oceans food chain …

    Krill oil is usually twice as expensive as say pharmaceutical grade fish oil from mackerels/sardines, both renewable, and there still remains some controversy about the absorption reality.

    where as I use to use krill for the added boost of Astaxanthin, However I stopped because of global ecosystem concerns. One certainly can’t emply that one doesn’t get enough omega -3 goodies w/ a high grade fish oil. And as well there is no need to buy expensive salmon based oil. That’s simply a marketing ploy !

    • Richard A says:

      Dr. Mercola convinced me to switch to Krill years ago for all the reasons stated in this article.
      He also stated that Krill are the largest biomass on the planet and , contrary to your assertion, Krill are a virtually inexhaustible renewable resource. I’m curious to know the source of your information.

  2. Sharon Peterson says:

    Thank you for this very informative article on Krill Oil. It was very informing.

  3. One thing I want to touch upon is that weight loss program fast can be achieved by the appropriate diet and exercise. Your size not just affects appearance, but also the quality of life. Self-esteem, depression, health risks, as well as physical capabilities are afflicted in putting on weight. It is possible to do everything right and at the same time having a gain. If this happens, a problem may be the reason. While excessive food and not enough workout are usually at fault, common health conditions and trusted prescriptions might greatly help to increase size. Thx for your post right here.

  4. roger anderson says:

    Krill oil is the basic food of most marine inhabitants.
    It is suicide to promote it. We will kill off the last bit of life in the oceans. Why not promote rhino horn.!!

  5. Esther Egan says:

    I have dry lips. I have had this problem for a number of years now. I drink plenty of water, put Vicks on my lips at night, and take a number of vitamins. I also take Krill and Fish oil. How much would I take of the oils to benefit me and my lips. It seems one week, my lips are about to heal and the next back to dry. I am taking SSKI right now and my lips seem to be responding. I was told to take higher doses of fish oil, so how much would I take?

    • Carolyn Banach, MS, RD says:

      Thank you for participating in this discussion.

      My first suggestion would be to discontinue the use of Vicks on your lips, it could be making it worse. Lastly, I recommend reading our article “7 Natural Ways to Heal & Prevent Chapped Lips” for natural remedies:

  6. I’m not seeing any information about shellfish properties of krill oil, which I’ve read about before.
