Krill Oil Environmentally Friendly?

As we know, krill is mostly harvested for its oil due to the fact that it’s a highly abundant source of Omega 3 fatty acids (particularly DHA and EPA) along with astaxanthin, a carotenoid known for its powerful antioxidant capabilities.

Some questions that may be on people’s minds are:

Does krill have excellent sustainability?
Is krill harvesting harmful to the environment?
Are krill an endangered species?

First of all, krill makes up the largest biomass on earth – weighing more than any animal population or for that matter, the human population.

Secondly, because there are more krill on earth than any other creature, it is a strong indication that krill is in no danger of becoming extinct at any time in the near future.

In fact, krill harvesting has great environmental sustainability and rest assured there is no threat of krill being over-harvested.

Like any other industry, krill harvesting is also closely monitored and carefully regulated to ensure its environmental sustainability. The Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR), is an international environmental organization comprised of 25 countries. CCMALR’s mission is to preserve marine life and the environmental integrity within and surrounding Antarctica. CCAMLR is considered an exceptional organization for its highly detailed research programs to help ensure successful conservation practices (especially of krill) in the Southern Ocean.


Studies

How does it work?

Krill oil contains fatty acids similar to fish oil. These fats are thought to be beneficial fats that decrease swelling, lower cholesterol, and make blood platelets less sticky. When blood platelets are less sticky they are less likely to form clots.

High cholesterol. Developing research shows that taking 500mg of a krill oil product daily reduces total cholesterol and “bad” low-density lipoprotein (LDL) cholesterol, and increases “good” high-density lipoprotein (HDL) cholesterol in patients with high cholesterol. Higher doses of 1,000mg daily also appear to significantly reduce levels of triglyceride, another type of blood fat.

Osteoarthritis. Early research shows that taking 300 mg of a specific krill oil product daily reduces pain and stiffness in people with osteoarthritis.

Premenstrual syndrome (PMS). Early research shows that taking a specific krill oil product might reduce PMS symptoms.


Rheumatoid arthritis. Early research shows that taking 300 mg of a specific krill oil product daily reduces pain and stiffness in people with rheumatoid arthritis.


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 krill oil group.

During the study, CRP levels were measured three times: at the beginning of the study, after seven days and after 14 days. Here are the results they found…

After 7 days, the placebo group’s CRP levels increased by 15.7 % while the krill oil group REDUCED their CRP levels by 19.3%

After 14 days levels in the placebo group increased again by 32.1% while the group that had been taking 300 mg of krill oil daily reduced their CRP levels by 29.7%!.

Findings from a study conducted at McGill University in Montreal indicate that krill oil helps sustain healthy cholesterol levels. Participants were divided into four groups:

Group A was given .5 – 1.5 grams of krill oil daily
Group B was given 2 – 3 grams of krill oil daily
Group C was given 3 grams of fish oil daily
Group D was given a placebo.

Findings revealed that individuals taking just 500mg of krill oil daily achieved improvement in sustaining good (HDL) cholesterol levels compared to individuals taking 3 grams of fish oil.

Krill Oil also contains:

Phospholipid-derived fatty acids (PLFA), which may result in better absorption, and marine lethicin2
A carotenoid antioxidant called astaxanthin. Antioxidants inhibit oxidation and may neutralize the oxidant effect of free radicals and other substances in body tissues that may lead to disease.

Warnings issued by the FDA note that certain fish (marlin, tuna, swordfish) may contain toxins such as methylmercury, leading some consumers to be wary of eating fish to obtain omega-3 fatty acids. 

One of the advantages of Krill Oil over Fish Oil is that it does not lead to the fishy aftertaste, reflux or belching of fish flavors, a common side effect with fish oil supplements.
