Krill Oil Benefits - How is it different from Fish Oil?

Author: ANCP   Date Posted:26 May 2016 

Krill are small prawn-like crustaceans found in the waters of the Antarctic Ocean. They are a rich source of the omega-3 fatty acids eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), so it’s not surprising that fish oil and krill oil are similar in many ways. However, krill oil has some additional unique properties that fish oil does not.


Enhanced absorption and utilisation

Most of the omega-3 fatty acids found in krill oil have a different chemical structure to those found in fish oil, with the majority being attached to phospholipids. In contrast, omega-3s from fish oil are attached to triglycerides . Thanks to this structure, krill oil omega-3s are significantly easier for the body to absorb and utilise than fish oil omega-3s.

  • Phospholipids – Most of the omega-3s in krill oil are bound with phospholipids, which are thought to be responsible for helping to transport EPA and DHA through the body and assist their integration into cell membranes. These phospholipids are major structural components of every cell in our bodies and along with the omega-3s, they form the cell membrane ‘skin’ surrounding the cells of every living thing.





Sustainability at Australian NaturalCare


  • At Australian NaturalCare we only use premium quality, sustainably sourced krill oil. Our krill oil supplier has voluntarily worked with the official international body responsible for the conservation of marine life in the Antarctic (CCAMLR), as well as leading international conservation groups, and ensures that the controls and sustainability of each harvest exceed the requirements set by CCAMLR. It is the only krill harvesting company in the world to do so.
  • Women’s health - Omega-3 fatty acids from both fish oil and krill oil have been used to aid the management of PMS and period pain, however, there is some evidence that krill oil is more effective at reducing emotional symptoms (such as feeling stressed or overwhelmed) and some physical symptoms (such as breast tenderness and joint pain). Both sources of omega-3 appear to be similarly effective for other physical symptoms, such as bloating and abdominal cramps.
  • Brain and eye function - Omega 3 fats essential for brain and eye health and help to maintain their normal function.
  • Astaxanthin – Along with prawns, crabs and some fish, krill contain a red-coloured carotenoid called astaxanthin, which is a powerful antioxidant and free radical scavenger.
