Krill Oil is most often used for
Krill Oil is an oil that is derived from krill; it contains the same two fatty acids that Fish Oil contains (Eicosapentaenoic Acid, or EPA, and Docosahexaenoic Acid, DHA). However, a large portion of the EPA and DHA in krill is in the form of a phospholipid, with a phosphate group on the end of the fatty acid. This results in higher bioavailability (rate of absorption) of krill oil, and thus the same effects of Fish Oil can be seen with Krill Oil but at a lower dose.
Supplementation of Krill oil tends to be in the range of 1-3g daily (overall oil weight), which has been used in the clinical trials of krill oil supplementation.
If supplementing in accordance with the omega-3 content, the omega-3 content that is supplemented from krill oil should be equal to approximately 2/3rds that used with basic fish oil supplementation to account for the increased absorption. If one were to normally supplement 1000mg EPA plus DHA, then 660mg of EPA and DHA from krill oil would be equivalent.
