Krill Oil – The Studies are So Good They’re Shocking!

Move over fish oil, there’s a new sheriff in town; and his name is Krill. 


The studies on Krill oil, for joint comfort and flexibility, for focus and concentration, for the symptoms of PMS, for cholesterol and triglycerides, even for healthy blood sugar, are so good they’re shocking.  I will outline the pros and cons of Krill oil for you below.

In a randomized placebo controlled trial with 90 patients who received either 300 mgs of Krill Oil or a placebo, after just 7 days the group taking krill oil had 28% less pain!! After 30 days pain was reduced by 38%(wow) !!! The krill supplementation also enhanced joint function and flexibility.1

Another study using 500mgs of Krill oil was done with a group of adults who had ADHD.  After just 3 months of supplementation, concentration, planning skills and focus were all 47-50% better (wow).2

The first results my patients look at when they get their blood work are: cholesterol (total, LDL and HDL), blood sugar and triglycerides.  I call these the “big 3.”  So the results of the study I’m about to outline for you get my patients very excited.  One hundred twenty patients were assigned to 1 of 4 groups. They either received 1-1.5 grams of krill oil (depending on their body mass index), 2-3 grams of krill oil (again, depending on their body mass index), 3 grams of fish oil, or a placebo.  After 3 months of supplementation, the patients in the 1-1.5 grams of krill oil group dropped their total cholesterol by 13.5%, with their LDL’s (bad cholesterol) dropping by 33.9% and their HDL’s (good cardioprotective cholesterol) rising by 43.3%.  Their triglycerides went down by 11.5% and their blood sugar dropped by 6.3%.3

The patients in the 2-3 grams of krill oil group dropped their total cholesterol by 18%, with their LDL’s (bad cholesterol) dropping by 38% and their HDL’s (good cholesterol) rising by 57.5%.  Their triglycerides went down by 27% and their blood sugar dropped by 5.6%.3

The subjects taking 3 grams of fish oil dropped their total cholesterol by 5.9%, with their LDL’s (bad cholesterol) dropping by 4.6% and their HDL’s (good cholesterol) rising by 4.2%.  Their triglycerides went down by 3.2% and their blood sugar dropped by 3.3%.  These results are good, but as you can see, not even close to the results gleaned by those taking krill oil.3

Finally, blood parameters in those taking a placebo remained generally similar during the 3 month study.3

As we look at these results, one can only marvel at how incredibly positive they are.  And this is from a completely natural substance which provides benefits to all of the cells and tissues in the body with no side effects.  I wish that I could say this about all of the medical drugs my patients are taking.

Finally, the results for PMS are remarkable.  If you suffer from PMS pay close attention to this study.  Over a period of 90 days, 70 women took either 1 gram of krill oil or fish oil.  For the first month they took the supplements daily.  Thereafter they supplemented for 8 days prior and 2 days during menstruation. After 90 days:

Bloating was reduced by 21% in the krill group and 10% in the fish oil group.

Weight gain was reduced by 15% in the krill group and 29% in the fish oil group.

Abdominal pain was reduced by 34% in the krill group and 20% in the fish oil group.

Swelling was reduced by 37% in the krill group and 25% in the fish oil group.

Stress was reduced by 38% in the krill group and 12% in the fish oil group.

Depression was reduced by 39% in the krill group and 13% in the fish oil group.

Breast tenderness was reduced by 42% in the krill group and 15% in the fish oil group.

Feelings of being overwhelmed were reduced by 42% in the krill group and 4% in the fish oil group.

Irritability was reduced by 47% in the krill group and 10% in the fish oil group.

Joint Pain was reduced by 64% in the krill group and 23% in the fish oil group.4

The studies which I have outlined above show the incredible benefits of krill oil for human health.  In fact, in these studies krill oil outperforms fish oil; but we need to understand is that these are just a handful of studies.  There are literally tens of thousands of studies on fish oil showing the incredible benefits that the omega 3’s: EPA and DHA from fish have on human health.  Benefits for the joints, the heart, vision, brain health, memory, mood, learning, inflammation, blood pressure, arterial flexibility and the list goes on and on.

The point is this, we don’t want to jump from the fish oil band wagon to the krill oil bandwagon just yet; there simply is not enough data.  Furthermore, krill oil tends to be relatively weak in terms of its content of the essential omega 3 oils: EPA and DHA which are the reason that we supplement with fish oil.  Unfortunately, the leading brand of krill oil has only 72 mgs of EPA and DHA per serving while the next most popular krill oil has just 140mgs of EPA and DHA per serving (2 caps).  That’s very low considering that the American Heart Association recommends that we get 500 to1000mgs of EPA and DHA per day.5  The Council for responsible Nutrition points out that the average American gets about 100mgs of EPA and DHA per day from diet alone.  This leaves us at least 400mgs short per day requiring either increased wild caught fish consumption or daily supplementation to restore adequate levels.

Do to the high levels of contaminants in fish, including mercury, and the relatively low levels of omega 3’s in farmed fish, I recommend that my patients supplement to achieve a target level of at least 1,000mgs of EPA and DHA per day.  Two to three thousand milligrams per day for those with high triglycerides and or chronic pain.  If we have to use just Krill Oil to achieve these outcomes we would be taking a lot of capsules.  If we look at the two leading brands above for example, one would have to take over 10 capsules per day to achieve these goals.  Most of my patients are not willing to do this.

Krill oil promoters point to increased absorption and utilization for the krill based omega 3’s, and they’re correct; but it’s just too soon to risk giving up fish oil and switching completely to krill oil unless you are willing to take it at the levels we just discussed. 

Fortunately, one of my favorite supplement companies has come up with the solution.  It’s so simple that I can’t believe it hasn’t been done sooner.  Purity Products has combined fish oil with the krill oil in a new product called Krill Omega-3 Super Formula. You may have seen me talk about it on TV or heard me on the radio.   Just 2 capsules of this Krill Omega formula have a total of 1,000 mgs of the omega 3’s: EPA and DHA and a full 300mgs of krill oil which is the same amount used in the joint study at the beginning of this article.  In addition each serving provides 1,000 IU’s of vitamin D, a nutrient which most of us are deficient in, making this formula arguably the finest omega 3 supplement in the world. 

In my opinion this is the evolution of omega 3 supplementation.  The benefits of Krill Oil combined with the benefits of concentrated, ultrapure fish oil.  I can see no reason to use another formula at this point.  I personally take 4-6 soft gels per day to support my heart, comfortable joints and sharp thinking.

Eat right, exercise, supplement wisely and maintain a positive mental attitude. That’s how we’ll age gracefully, together.
