Key differences between krill oil and other sources of omega 3s

Omega-3s’ impact on heart health is well researched. However, there are important differences between the various sources that need to be taken into consideration.

Let’s take a closer look at 3 key differences.


1) Phospholipid omega-3s

Krill contains phospholipid omega-3s, which have been shown to be more bio-efficient than other marine sources. Phospholipid-bound omega-3s (EPA & DHA) are better absorbed due to better bioavailability and therefore more efficiently delivered to the places that need it most.

2) Compliance

Krill’s phospholipid omega-3s are highly efficient, which – compared to other marine sources – results in smaller capsules and less digestive upset.

If you have heart health issues, you are probably taking multiple pills. Thus, smaller capsules and less digestive upset is a key factor, as you get the opportunity to take smaller and potentially fewer pills.


3) The power of krill oil

A randomized, double-blind, placebo-controlled, multi-center U.S. study on krill oil and hearth health investigated the effects of krill oil on blood lipids in subjects with “borderline high” or “high” triglyceride (TG) levels.

300 subjects participated, and the five treatment groups included a placebo group (olive oil), as well as 4 groups taking 0.5, 1, 2 and 4 grams of krill oil daily.

The research results were remarkable. In those who have borderline high or high triglyceride levels, krill oil was shown to lower triglycerides without raising LDL, the “bad” cholesterol (which has been the case in some fish oil trials).  

And there’s more. Krill oil was shown to be able to raise subjects’ Omega-3 Index, particularly among those taking the highest amounts.

Dr. Clemens Von Schacky, co-inventor of the HS Omega-3 Index Blood test, states:

“It is interesting to point out that with the highest dose of krill oil, the omega-3 index increased by 70%. Even with the lowest dose of 500 mg krill oil, there was a significant increase. Thus, this might have an impact on the risk of sudden cardiac death, which has been demonstrated in several studies during the last decade.”
