Krill oil supplements are fairly new to the scene but are starting to make waves, thanks to their health benefits. They’re made from krill, a small crustacean eaten by other sea creatures. Supplement manufacturers extract the oil from krill to make it viable for their products. 

Also, krill oil supplements are drawing comparisons to the more known fish oil due to their similarities. Although, more research is needed for a better comparison between the two. Regardless, krill also provides many advantages since it contains omega-3 fatty acids (DHA and EPA), which are associated with many health benefits, including heart health [1]. 

We’ll find out more about those benefits as we get to the FAQs, but for now, let’s see the best krill oil supplements and what they can do for your health needs.
