What is Krill Oil?
Chances are if you ever heard of krill it was while watching a nature documentary about whales. Krill, it’s long been known, is a favorite food of whales who simply open their mouths and swim through vast swarms of the tiny crustaceans consuming tons at a time. In fact it is thought that one of the reasons species like blue whales (who eat vast amounts of krill) live so long (100+ years is not unusual) is because of the beneficial effects of eating krill.
As far as humans are concerned krill are too small to make an attractive seafood dish. However, when harvested and processed in large amounts krill oil is produced that is then used to create krill oil supplements like those profiled above. Some worry about the effects of harvesting krill for the purposes of creating supplements but the fact is krill are one of the most abundant creatures in the oceans, with estimated populations in the tens of trillions in the Antarctic alone. So as long as the harvesting is done in a responsible way the negative impact is considered negligible.
What are Some of the Benefits of Krill Oil?
As we mentioned krill oil is able to generate many of the same benefits as fish oil. But, because it also contains the powerful antioxidant astaxanthin its benefit package is even more comprehensive. Those benefits include:
- Anti-inflammatory properties – The omega 3 fatty acids (EPA and DHA) found in krill oil are known to have powerful anti-inflammatory properties (3). The presence of astaxanthin in krill oil is thought to enhance the anti-inflammatory properties of these fatty acids even further in a way unique to krill oil. Inflammatory diseases include all types of arthritis. So anything that will suppress damaging inflammatory behavior by the immune system is considered a good thing in most all cases.
- Improved cardiovascular health – The omega 3 fatty acids in krill oil are known to help reduce inflammation, lower blood pressure, reduce instances of blood clotting, reduce or eliminate irregular heartbeats and perhaps reduce the risk of heart failure and/or stroke. That’s a lot to expect from a fatty acid but both EPA and DHA deliver on this promise (4).
- Better overall health – The omega 3s in krill oil are also thought to play an important role in the prevention of a number of other diseases and conditions including heart disease, asthma, depression, ADHD and perhaps even certain types of cancer. While both fish oil and krill oil possess docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA) the greater bioavailability of these fatty acids in krill oil make it the safer bet for maintaining optimal health.
- Reduced joint pain – The anti-inflammatory properties of krill oil provide it with the means to significantly reduce pain caused by swollen joints related to osteoarthritis and other conditions. Krill oil may also have a beneficial role to play in speeding up recovery from joint injuries by reducing inflammation and increasing mobility.
- More tolerable PMS – Medical science has been searching for decades for way to mitigate the debilitating effects of Premenstrual Syndrome. Now, studies are beginning to show (5) that omega 3 fatty acids like those found in krill oil may in fact produce a measurable reduction in some of the most odious effects of PMS.
Does Krill Oil Have any Side Effects?
In the vast majority of cases krill oil is considered a safe and effective supplement. However, since krill is a type of crustacean those with an allergy to shellfish should avoid taking krill oil. In addition, it is possible that krill oil may produce a negative interaction with some medications. Therefore, if you are currently taking any medications you should talk to the prescribing physician before you begin to take krill oil supplements.
What Makes a Good Krill Oil Supplement?
Separating the good krill oil supplements from the not so good is not terribly difficult. Essentially you’ll want to check for the EPA and DHA content to make sure it’s within the range your doctor suggests you should be taking. You’ll also want to be sure your krill oil supplement includes the potent antioxidant astaxanthin as well as phospholipids which will help increase bioavailability. If you are concerned about possibly consuming genetically modified organisms make sure your potential supplement says on the label that it is GMO free.
Who Can Benefit from Krill Oil?
- People with arthritis – Because of the powerful anti-inflammatory properties of omega 3 fatty acids people suffering from any stage of arthritis should talk to their doctor about taking krill oil. That includes those suffering from osteoarthritis or the more ruthless rheumatoid arthritis (6).
- Athletes – The anti-inflammatory properties of krill oil make it attractive to athletes who regularly put enormous stresses on their muscles and joints. 500 mg of krill oil per day is often enough to significantly reduce inflammation and help athletes recover quicker from strenuous workouts and performances.
- Those with elevated cholesterol levels – High levels of LDL cholesterol can significantly increase a person’s risk of heart attack or stroke. Krill oil is known for its ability to help reduce cholesterol levels (7) which makes it a must for people with a vested interest in reducing their chances of heart failure.
- Women who suffer from PMS – As mentioned above studies have shown that krill oil may have an important role to play in reducing some of the more debilitating effects of premenstrual syndrome. Bloating, mood swings, depression, headaches and more may all be alleviated to some degree by krill oil.
The Bottom Line
For years krill oil has existed in the shadows of its more famous cousin, fish oil. But that has begun to change recently. People the world over are discovering that krill oil not only delivers many of the same benefits as fish oil but does so in a more efficient and effective manner while also providing potent antioxidants that help combat the scourge of free radicals. If you are interested in attaining a higher degree of overall health ask your doctor if a krill oil supplement might be right for you.
