Fish Oil vs. Krill Oil: What’s the Di?erence?
Understanding Fish Oil and Krill Oil
Fish oil and krill oil are two popular sources of omega-3 fatty acids commonly used in dietary supplements. Both naturally contain EPA and DHA, two omega-3s widely recognized in modern wellness supplements.
Fish oil is commonly sourced from oily fish species naturally rich in omega-3 fatty acids, while krill oil is derived from small crustaceans known as krill, which are commonly harvested from cold ocean waters, including Antarctic regions.
What Makes Krill Oil Different?
Krill oil naturally contains omega-3s in phospholipid form, a structure commonly discussed in wellness and nutrition research. It also naturally contains astaxanthin, a red carotenoid compound responsible for krill oil’s distinctive color.
These structural characteristics are some of the main features that distinguish krill oil from traditional fish oil supplements.
Why Do Some People Prefer Fish Oil?
Fish oil remains one of the most widely used omega-3 supplement forms because of its concentrated EPA and DHA content and long history in daily supplementation.
Modern omega-3 supplements are available in several forms, including fish oil and krill oil, both of which continue to be widely used in contemporary wellness routines.
