10 Best Krill Oils for Omega-3 Fats

10 Best Krill Oils for Omega-3 Fats

Fish oil is often considered to be one of the greatest “wonder supplements” the industry has ever known, treating everything from the heart, joints, brain, skin, inflammation, hormone regulation, etc. The list goes on. The shear amount of general health benefits provided by fish oil is pretty astounding.

Then, a few years ago, we discovered krill oil. And ever since, it’s been promoted as the next big thing, specifically, as it relates to essential fatty acids and omega-3 supplementation.

Krill Oil Explained

Krill are shrimp-like shellfish found in every ocean and are a major food source for marine life. One of the most abundant (and fished) sources of krill is Euphausia supera, or Antartic Krill.

Like fish, krill consume foods naturally high in fats, such as algae. As a result, krill become rich sources of omega-3 polyunsaturated fatty acids (PUFAs), eicosapentaenoic acid (EPA), and docosahexaenoic acid (DHA).

That said, consuming enough healthy fats in the diet is vital for normal bodily function. Not getting enough good fat can cause deficiencies and lead to numerous cardiovascular issues. Quality krill oil can help mend this nutritional gap and help keep you performing at your best.

Best krill oil choices based off:

  • Clean, high-quality sources of krill oil
  • Helps support your overall health
  • Provides a wide range of health benefits
  • Small, easy to swallow soft-gels
  • Highly bioavailable source of healthy fats
  • Easily digestible with no fishy aftertaste
  • Safe and effective alternative to Fish Oil
  • Helps protect cells from damage with antioxidants

Krill Oil may be more bioavailable than fish oil.

In fish oil, most omega-3 PUFAs are bound to triglycerides, while in krill oil, they’re bound to phospholipids [1]. When compared to fish oil, studies have suggested that krill may be more bioavailable because of lower doses required for a similar blood level of DHA and/or EPA [2]. This is likely because of krill oil’s chemical structure, which may be absorbed more efficiently.

It also provides an effective antioxidant.

Naturally found in certain types of algae, astaxanthin is a powerful antioxidant. This carotenoid is responsible for the reddish pigment seen in krill, shrimp, salmon, lobster, and other seafood.

Clinical research is coming together to suggest astaxanthin is anti-inflammatory, anti-apoptotic, anti-oxidative (protects cells), and may help promote or maintain neural plasticity [3]. These effects implicate astaxanthin to be a useful agent for encouraging healthy brain function.

Now that you are familiarized with the benefits of krill oil supplementation, here are our top 10 recommended best krill supplements.

Additional Krill Oil Supplement Benefits

Krill Oil for Cardiovascular Health

Results from a study published in the Journal of the American College of Nutrition reported that krill oil can significantly help maintain healthy inflammatory pathways. The study was conducted by measuring the presence of C-reactive protein (CRP) levels in the blood. One way to measure the risk of cardiovascular health is to determine the amount of the body’s CRP levels. The lower the CRP levels, the healthier the heart. Participants of the study were divided into two groups; a placebo and a kill oil group.

During the study, CRP levels were measured three times, which started at the beginning, 7 days after the study concluded, and 14 days after the study concluded. The study found that:

  • After 1 week (7 days), the placebo group had increases of CRP levels by 15.7%, while the krill oil group reduced their CRP levels by 19.3%, resulting in a total variance of 35% in favor of the krill oil group.
  • After 2 weeks (14 days), the placebo group had increases of CRP levels by 32.1%, while the krill oil group reduced their CRP levels by 29.7%, resulting in a total variance of 61.8% in favor of the krill oil group.

Krill Oil for Cholesterol Health

At McGill University in Montreal, a study was conducted that shows us that krill oil sustains healthy cholesterol levels. The study divided participants into 4 groups:

  • A: Given .5 – 1.5 grams of krill oil per day
  • B: Given 2-3 grams of krill oil per day
  • C: Given 3 grams of fish oil daily
  • D: Given Placebo

The findings revealed that individuals who took just 500mg (Group A) of krill oil per day achieved greater improvements in sustaining good cholesterol (HDL) that individuals who took 3 grams of fish oil per day.

Krill Oil for PMS Distress

Though I can’t speak as a woman, I’ve spoken and with many regarding the benefits that krill oil has on easing the distress of PMS. Women love this stuff for its ability to ease the anguish of PMS. When looking at the research analyzed on the effects of krill oil on menstruating women, not only was PMS-related stress reduced, but krill oil was also shown to be far more effective than women who used standard fish oil supplements during the study. The results of the study showed decreases in:

  • Emotional Mood Swings
  • Unwanted Fluid Retention; and
  • Cramp Discomfort

Krill Oil for Joint Function

With millions of men and women around the world suffering from joint pain and discomfort, a supplement like krill oil is a perfect, simple opportunity to find relief. One study, in particular, published in the American Journal of Nutrition analyzed krill oil’s effectiveness to lubricate joints and support healthy inflammatory responses. The participants of the study experienced:

  • Reduction in Joint Stiffness
  • Less Joint Stress; and
  • Increase in overall mobility

Krill Oil for Cognitive Function

Naturally, as we know, there are deteriorations associated with the aging process. For one, memory, clarity, and alertness all begin to slowly decline. For those entering the later years of their lives, krill oil is something to seriously consider adding to your supplement arsenal. With several scientific studies that demonstrate significant brain health benefits associated with omega-3’s and krill oil, which include:

  • Study 1: 30 adults with attention difficulties were shown to have increased mental concentration and mental focus after only 90 days of krill oil supplementation.
  • Study 2: Higher levels of omega-3’s in older adults resulted in better concentration and prevention of memory loss than those with lower omega-3’s.
  • Krill oil contains astaxanthin, a powerful antioxidant, which helps to maintain cellular integrity by crossing the “blood-brain barrier”.

Krill Oil for Healthy Skin

Oxygen radical absorbance capacity, or “ORAC”, which is a scale that measures the effectiveness of antioxidants and their ability to fight free radicals. Krill oil has actually been shown to carry an ORAC value of 43, which as standard fish oil is only 8… Astaxanthin, a powerful antioxidant, is known to defend cells against the effects of damaging free radicals, which helps to protect skin health and achieve the beautiful complexion you’ve always wanted.

The Bottom Line

We could go on forever about the many supportive health benefits of (good) fatty acids like those found in krill oil. But to achieve these benefits, you have to consume enough of them. Western foods barely provide any.

If you or a loved one have to deal with inflammation, high-cholesterol or feel the onset of arthritic symptoms, supplementing with krill oil may very well help [4].

Krill oil is by and large arguably superior to fish oil. As a result, countless people have added it to their fat deficient diets in hopes of improving their well-being. For many, it’s been a saving grace for unwarranted bodily pain and has served to even help others around them.

So, as long as you aren’t allergic, try it. If it helps, that’s worth a million bucks in our book.
