Omega-3 Krill Oil

Recently krill oil has been gaining popularity as a superior source of omega-3 fatty acids. But what exactly is krill oil and is it better than fish oil?


Krill are tiny shrimp-like crustaceans that live near Antarctica and are a staple food source for baleen whales and penguins. Oil extracted from these small sea creatures are being extracted and manufactured into capsules as a source of omega-3 fatty acids for human consumption. Omega-3 fatty acids are famous for their numerous health benefits: everything from boosting the immune system and increasing brain function to preventing cancer and heart disease. Krill oil also contains vitamin A, vitamin E, vitamin D, and astaxanthin, a powerful antioxidant that protects your skin from UV-damage.

The components of omega-3 fatty acids, DHA and EPA, are have a different structural arrangement in krill oil versus fish oil. This structural difference allows the krill oil to be more easily absorbed by the human body thus preventing “fish burps” commonly associated with fish oil capsules. Krill oil has been found to decrease LDL (bad) cholesterol, increase HDL (good) cholesterol, and lower blood sugar. It has also been shown to be an effective treatment for reducing aches, pain, inflammation, and PMS.


Krill oil capsules are slightly smaller than fish oil capsules in size but tend to be more expensive. The red pigment of the capsules comes from the red algae that krill consume as part of their diet. Most products recommend that you take 1 krill oil capsule/day and people with shellfish allergies should not take krill oil. While the research is still new on krill oil capsules, it appears that there are no adverse side effects to taking them. Overall, krill oil seems to have similar effects as fish oil with a few added perks. You can find krill oil capsules at your local health food store and give them a try!
