Benefits of Krill Oil

April 4, 2019 by

Krill oil is a healthy oil that comes from a small shrimp-like crustacean called a krill. This oil is known for providing people with healthy omega-3 fats, antioxidants, and phospholipids, which plays a significant role in the absorption of other nutrients.

Krill is a critical player in the global food chain because it fuels the Earth’s marine ecosystems. Krill eat microscopic, single-celled phytoplankton, but hundreds of different creatures in turn feed on krill, including birds, squid, fish and even whales.

Aside from being very sustainable, krill are known for their longevity, with a life span of up to ten years. This makes krill oil an eco-friendly choice for an omega-3 supplement.

Fish oil is extracted from the liver of oily, cold-water fish. While krill oil is often interchanged with fish oil, there are clear differences between the two that make krill oil the superior choice.

First, it has a higher potency with 48 times the antioxidants as fish oil. It is also much more potent in its metabolic effects, meaning you need to consume much less krill oil to get the same benefits as fish oil.

Krill oil is also free from contaminants, unlike fish oil that is extracted from fish that often contain heavy metals and mercury. Because krill are small and they are at the bottom of the food chain, they do not pose this same risk.

Krill is also more easily absorbed by your body due to its phospholipid factor. It also contains phosphatidylcholine, which helps send nerve signals to your brain and increases the bioavailability of krill oil, and trimethylglycine, which can help protect your liver.

Fish oil is prone to oxidation which can lead to free radicals in your body, but krill oil contains a substance called astaxanthin, which makes it more stable and less likely to oxidize in your body. This decreases your need for antioxidants.

Research has also found that krill oil has a better influence on metabolism than fish oil. One study that looked at the livers of mice given krill oil or fish oil found that unlike fish oil, krill oil improves the metabolism of glucose in the liver, promotes lipid metabolism, and improves the function of the mitochondrial respiratory chain. Also, krill oil decreases cholesterol while fish oil increases it.

When looking for a krill oil supplement, look for one that is certified by the Marine Stewardship Council, who recognizes fisheries following sustainable fishing practices.
When a krill oil is MSC-certified, it means that the manufacturing has undergone a high global standard to make sure the product is sustainable.

You also want to make sure that the krill oil is produced using Antarctic krill because this is the most abundant. It should not contain heavy metals, dioxins, PCBs, or other contaminants. You also want to make sure that it is cold-processed, which preserves its health benefits. Your krill oil should be in hard capsules rather than soft gels because the softer coatings let more oxygen enter the krill oil, which can lead to oxidation.

Over two dozen health conditions have been noted to benefit from the use of krill oil, including heart disease, osteoarthritis, rheumatoid arthritis, kidney disease, cognitive or neurological disorders, and autoimmune diseases. One of the most common side effects of fish oil is a fishy aftertaste or the belching of fishy flavors. This effect is reduced with the use of krill oil, assuming you are purchasing a high-quality product from a reputable brand. However, some krill oil brands can also lead to side effects such as heartburn, nausea or upset stomach, bad breath, and loose stools.

While krill oil is usually safe for most of the population, it is still important to consult your doctor before taking this supplement, especially if you suffer from any type of disease or are currently taking other medications or supplements. If you are pregnant or breastfeeding, you should also talk to your doctor before taking krill oil.

If you are on anticoagulants or any other blood thinners or you have a blood clotting disorder, do not take krill oil because it can slow down blood clotting. You should also take caution before taking krill oil if you have an allergy to seafood.
