Krill oil is a supplement that is rapidly gaining popularity as an alternative to fish oil.
It is made from krill, a type of small crustacean consumed by whales, penguins and other sea creatures.
Like fish oil, it is a source of docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA), types of omega-3 fats found only in marine sources. They have important functions in the body and are linked to a variety of health benefits.
Therefore, it’s a good idea to take a supplement containing EPA and DHA if you don’t consume the recommended eight ounces of seafood per week (5).
Krill oil is sometimes marketed as being superior to fish oil, though more research on that is needed. Regardless, it may have some important health benefits.
