Fish oil is a source of the omega-3 fatty acids, including eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), which have been shown to be beneficial for heart, brain and joint health. With many of us not consuming an adequate intake of omega-3s, supplementing with fish oils has become a popular way of upping our intake to help support health and wellbeing. On the other end of the supplementation scale, fish oil is used to help provide relief from conditions associated with inflammation such as rheumatoid arthritis and also to help to support cardiovascular health.
Krill- the latest in nutritional oils
Antarctic krill or Euphausia superba are shrimp-like crustaceans found in the Antarctic Southern Ocean waters. Like fish oil, krill oil is a source of EPA and DHA, however, it’s the structure of omega-3s in krill that sets them apart from those in fish oil. Omega-3s found in krill oil are found as part of phospholipids.
Phospholipids are a type of lipid and are an essential component of our body’s cell membranes (the outer part of cells that control what goes in and out of our cells). The phospholipids found in krill oil are thought to enhance the absorption of EPA and DHA. And like EPA and DHA phospholipids play a role in supporting healthy brain function. Krill oil is rich in the phospholipid phosphatidylcholine, which helps to support healthy cholesterol metabolism and liver health and function.
Which one should you take?
If you’re after a nutritional oil supplement that is easy and convenient to take, supports brain health, cholesterol metabolism and healthy liver function and provides omega-3 then krill may be the oil for you.
Looking for a higher intake of omega-3s to combat the effect of conditions associated with inflammation? Fish oil provides a higher dose of omega-3s and with a good body of evidence for relief of inflammation associated with rheumatoid arthritis, osteoarthritis, and injury.
