PRO

  • Krill oil is derived from tiny, shrimp-like crustaceans that are abundant in cold waters of the Antarctic Ocean. It is effective in the same ways that fish oil is beneficial, including improving cholesterol and triglycerides, and reducing inflammation and the risk of cardiovascular events.
  • Krill oil is rich in EPA and DHA, two essential omega-3 fatty acids. Furthermore, krill oil improved absorption and delivery of DHA to the brain in animal studies.
  • Krill oil appears to be as safe as fish oil.
  • Krill oil requires a smaller dose to deliver the same benefits of fish oil.

CON

  • Krill oil has been studied only for its EPA and DHA content. Although the benefits of krill oil appear to be the same as those of fish oil, we recommend that krill oil be used only as an alternative until additional studies can be completed in humans.
  • Krill oil has not been studied as thoroughly as fish oil. Future studies are needed to confirm the benefits.
  • Side effects are similar to fish oil, the most common being increased gastrointestinal complaints.

* *ADVISORY* *
If you take medications that affect blood clotting, such as warfarin (coumadin) or aspirin, krill oil (usually more than 3000 mg of active component DHA+EPA) can increase your risk of bleeding. If you are taking any blood thinning medications, we recommend working with your medical provider before taking these supplements.

DOSAGE:Take 1-3 grams daily for treating high blood pressure or high cholesterol. Take 300 mg daily to decrease arthritis pain and inflammation.

CONCLUSION:We conclude that krill oil is a safe and effective supplement for improving cholesterol numbers and lowering inflammation. While it appears to have the same benefits as fish oil, and requires a lower dosage for the same benefits, it has not yet been thoroughly studied so we recommend using it only as an alternative. Remember to include it in your list of medications when you visit your doctor and other health care providers.
