Fish oil supplements are among the most popular supplements available today, as they seek to support cardiovascular health, promote healthy looking skin, and may support healthy cholesterol levels already in the normal range. However, many people are choosing to take an alternate fatty acid supplement: krill oil.
So is krill oil better than fish oil? What are the potential benefits taking this supplement?
What is Krill?
Krill are shrimp-like crustaceans that average about two inches (5cm) in length and reside throughout the open ocean, and it is estimated that there are nearly one hundred krill species throughout the world. The most well known krill are Antarctic krill, which thrive in the clear, icy waters around Antarctica. These krill (ranging in amounts from 125 million tons to 6 billion tons) congregate in swarms so dense they can sometimes be seen from space.
Krill can live up to ten years, and feed on phytoplankton on the oceanâs surface. Krill form an integral part of marine ecosystems, as they are the main staple in the diets of whales, birds, and fish. In recent years, krill has been identified as a source of many potential benefits for humans as well.
Why Try Krill Oil
Krill is a source of both DHA and EPA (docosahexaenoic acid and eicosapentaenoic acid), which are essential fatty acids that are sources of omega-3. Essential fatty acids are considered âhealthyâ fats, but your body doesnât naturally produce them. In order to get the essential fatty acids you need, you must obtain them from your diet or through taking a supplement. These fatty acids work to support healthy cholesterol levels already in the normal range, support a healthy internal response, promote a healthy weight, and may offer other potential health benefits.
Krill oil is also a source of phospholipids, which are a class of lipids that play a role in cell membrane health and help the cell maintain its internal structures. Maintaining phospholipids is essential for overall cell health. Additionally, it contains antioxidants (which is also the source of the krill’s red color), which work to protect cells from oxidation, and from free radical damage. Antioxidants also work to support cardiovascular health and healthy looking skin.
Is Krill Oil Better Than Fish Oil?
If youâre looking for an essential fatty acid supplement, whether you choose fish oil or krill oil ultimately comes down to personal preference. According to a 2015 study that looked at the levels of EPA and DHA obtained through krill oil and fish oil supplementation in a double-blind, randomized trial, both oilsÂ contain bioavailable essential fatty acids to support your health. Researchers noted,
Similar plasma and RBC levels of EPA + DHA were achieved across fish oil and krill oil products when matched for dose, EPA, and DHA concentrations in this four week study, indicating comparable oral bioavailability irrespective of formulation.
If you are looking for a bioavailable essential fatty acid supplement, krill oil could be a great choice!
