Q. What is Krill oil—and is it better than fish oil for omega-3 fats?

A. Krill are the tiny shrimp-like crustaceans eaten by whales and other marine animals. Wild salmon get their rich color from the krill they eat [1]. And like all seafood, krill contains the vital omega-3 fatty acids, EPA and DHA.

Here's what you need to know. There's no clear advantage of taking krill oil over other fish oil supplements. The vast health benefits of fish oil, specifically its bioactive components, EPA and DHA, have been documented in studies using: fish oil, EPA concentrates, DHA concentrates and not to mention, eating fish, itself.

Most fish oil is produced from sardines and anchovies, which are in abundant supply. Krill however, are a critical link in the marine food chain and is becoming endangered [2]

While there is no harm from taking krill supplements [3], it is best to choose a supplement that provides the right kinds of omega-3 and in the right amount.
