One of the most popular supplements in the last few years has been the use of fish oil as a health supplement. Fish oil was thought to have beneficial effects on our cardiovascular system, reduce inflammation and deliver a key dosage of healthy fats into the average diet. However, they also can be expensive, too much can deliver an unhealthy amount of mercury as a side effect and their potency can often be diluted.

Krill oil has emerged as a potentially better option than traditional fish oil, offering all of the same benefits but in smaller doses and with less risk of side effects. Krill are very small fish often consumed by whales and the like in artic climates, particularly the Antarctic area. They are high in health fats and oils and are thought to be just as beneficial as fish oil in reducing inflammation and being a key supplement for diets or cases of high cholesterol or fats needing to balance out. In this article, we’ll examine exactly what krill oil is, how it is best used and the best products on the market today.

What is Krill Oil?

Krill are tiny sea creatures that can best be described as tiny versions of shrimp. They are fed on by whales and are commonly found in the arctic, including the most popular version found in the waters near Antarctica called euphuasia superba. They’re a swimming crustacean, and they live in very large schools of up to 30,000 krill per cubic meter.

The traditional process for extracting krill oil comes from fisherman capturing krill in the open water, extracting the oil from them and then packing the oil into pre-designated capsules as a potential supplement. Different processes exist for extracting the krill oil but center on extracting it with minimal contamination or loss of the critical EPA/DHA components, which are the healthy fats that make krill oil the anti-inflammatory solution it portends to be.

Krill oil is used as a nutritional supplement in a similar way to fish oil, since it contains many of the same nutrients. Like fish oil, krill contains omega-3 fatty acids and phospholipid-derived fatty acids.

In many ways, krill oil is even more beneficial than fish oil. Krill oil has an additional antioxidant, which helps protect your cells from free radicals. It’s also more likely to be free of harmful metals like mercury, unlike fish. Since krill oil is made from Antarctic krill, it’s inherently made from relatively clean and unpolluted waters.

The nutrients in krill oil are also easier for the body to absorb. In nature, krill feed on phytoplankton, which are tiny photosynthesizing creatures. Since this is the main part of their diet, krill are directly absorbing the nutrients made available by these powerful photo-synthesizers. In turn, krill contain an abundance of nutrients that are often difficult for humans to obtain elsewhere.

Krill oil is often used for its overall health benefits. Scientific research has also shown it to be beneficial for improving the symptoms of arthritis and for reducing PMS side effects. Other uses that are not scientifically documented include using it for high blood pressure, stroke, and depression.

Common Forms of Krill Oil

The primary ingredient of any krill oil supplement is, of course, krill oil. However, every product will have differing levels of krill oil, an important measure to keep track of will be the mg of krill oil per dose as that will inform on the potency of the product in each serving.

Additionally, krill oil tends to be combined with other ingredients at times, such as astaxanthin, a carotenoid antioxidant used to fight free radicals and inflammation, all of which may be a factor in which product is best for you.

Finally, the source of the krill oil and the method by which it is extracted may be an important consideration, some sources use all organic while others create more synthetic blends.

Benefits of Krill Oil?

The health benefits of krill oil stem primarily its levels of oil and good fats. Krill oil contains the omega-3 polyunsaturated fatty acids EPA (Eicosapentaenoic Acid) and DHA (Docosahexaenoic). These are effective fatty acids for reducing triglycerides and potentially preventing coronary disease. They are also critical for reducing inflammation in the body.

One of the primary differentiators of krill oil as compared to fish oil is their delivery method. Krill oil is absorbed by the body and carried to its cells in phospholipid form, making it easier to absorb. Krill oil not only lowers LDL or low-density lipoprotein levels, it is also thought to raise HDL or high-density lipoprotein levels, which help to keep the cardiovascular system healthy.

Who Is Krill Oil Best Suited For?

In short, just about everyone who doesn’t get enough healthy fats or fish in their regular diet. While as a generality this probably includes most of us, it would specifically apply to those who are especially active and thus require more nutrients, such as athletes or gym enthusiasts, and those who do not get much naturally occurring healthy fats in their diet.

It is especially useful for those who are battling chronic inflammation symptoms, such as the early signs of arthritis, or those who anticipate that may be a future issue, as well those who may be battling or anticipating coronary issues due to higher fat or cholesterol levels.

Taking Krill Oil & Precautions

As with any supplement or health-related product, it is always advised to consult with a medical professional on if it is the right choice for you, and it is also always advised to follow the recommended dosing strategy by the product.

When taking a krill oil supplement, if the dosage and/or overall consumption is in line with the recommended dose, there are no side effects generally speaking. However, once you begin to increase dosage amounts beyond that level, you may begin to see possible side effects such as diarrhea, nausea or vomiting, and an upset stomach. These are essentially your body’s way of telling you you’ve had too much, and it doesn’t need the excess.

As another consideration, if you have a seafood allergy then practice extreme caution with krill oil supplements and be sure to consult a medical professional prior to use to ensure that it is safe for you. Also, though it would take extreme amounts, most seafood-based supplements contain trace amounts of mercury, which when too much is taken could lead to health issues, though as mentioned it would take an extreme amount far beyond the recommended dosage. Finally, due to its qualities that positively affect the coronary system, it can have blood thinning effects in the right set of circumstances, though it is not common. Make sure to consult a medical professional if you are not sure about this.

If you are unsure what the proper dosage is, consult with your medical professional and check the product packaging for the RDA (recommended dietary allowance) as well. The RDA will vary depending on age, gender and in general your activity level as well.

Always speak with your doctor before taking any supplements.

Things to Look For in a Good Krill Oil Supplement

Most krill oil products will have little variability in their ingredients, generally it will just be krill oil, therefore you’ll have to identify which version of krill oil is the right choice for you and look for that option. Krill oil comes in capsule forms, powders to mix with drinks, drops and more. It is also often combined with other ingredients, which is a factor to consider.

Be sure when selecting a product to review any additional ingredients aside from krill oil, such as additional supplements, fillers, artificial additives etc. as these may carry their own side effects or dilute the quality of the product.

Finally, as with any good product decision, look for reputable brands that are backed by strong scientific backgrounds, as well as offering a strong value. A good rule of thumb in terms of comparing price and value is to evaluate the price per dose rather than overall dose, as most products will have varying sizes.

A high-quality krill supplement should contain only pure krill oil, without any added filler oils. You can also look for a supplement that doesn’t have artificial flavors, coloring or preservatives; though often a little higher in price, this can be worth the peace of mind.

Krill supplements should also specify the amount of fatty acids and astaxanthin, the antioxidant found in krill oil.
