Krill Oil Vs. Fish OIl

Are you confused about which fishy oil you should be taking? Krill oil? Fish oil? Wondering what the difference between these omega-3-filled oils is?

Omega-3 fatty acids like krill and fish oil get a lot of hype in the health and nutrition world.  They are both boasted as being superfoods and healthy fats that we should be getting more of. Below, we will look at both oils, their similarities, differences and which you should be taking.

What is Krill Oil? 

What is Krill Oil? 

Krill oil comes from a tiny shrimp-like crustacean that lives in the cold icy Antarctic waters. They are found in large numbers in every ocean.  Its main health benefit is its rich source of the omega-3 fatty acids eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA).  These omega-3 fatty acids are important to our health. In addition to these omega-3 fatty acids, krill oil also contains astaxanthin, an antioxidant, as well as the nutrient choline.

Krill oil is said to have a higher concentration of EPA, and people report that there is less fish burping that commonly comes with taking fish oil supplements. In addition, the omega-3s in krill oil are packaged differently from fish oils.  They are packaged in a way that makes it easier for the body to absorb. Manufacturers claim the absorption rate is up to 60% better, meaning you can take less capsules to get the desired benefits.  For example, people taking fish oil to treat arthritis may need to take between 9 and 14 capsules a day. However, krill oil’s higher absorption rate means they would only need to take 1 capsule for the same desired effect.

Some other benefits of krill oil include:

  • Linked with reducing arthritis pain and symptoms
  • Prevents heart disease and other cardiovascular issues
  • Helps to combat inflammation in the body
