Wondering which omega-3 supplement you should take? While fish oil and krill oil can both be beneficial for our bodies, there are a few differences to consider. Here we look at how fish oil and krill oil differ, to help you make the right choice.
What is Krill Oil?
Around the Antarctic, in freezing waters, reside crustaceans that are high in eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) – fatty acids that are vital for maintaining good health. These fatty acids are also found in fish oil, though in krill oil they are packaged as phospholipids. These are much easier for our bodies to absorb. They also contain antioxidants and choline – another must-have nutrient.
Krill: A Better Absorption Rate
Research says krill oil is absorbed up to 60 per cent faster than fish oil. This means you need less of it to get the same benefits as fish oil. Manufacturers also reckon it's better for us, saying it's safer since the crustaceans come from cleaner waters. Although it's hard to know if that's just marketing spin.
What is Fish Oil?
Fish oil is extracted from cold water fish. Their oil is high in long chain omega 3 fatty acids – just as krill oil is – which have been shown to reduce rates of cancer, heart disease and other chronic illnesses.
Why Choose Fish Oil?
Compared to krill oil, fish oil has been studied extensively. It's been around for eons and scientists say it's heart healthy. It may also lower cholesterol, ease rheumatoid arthritis, reduce period pain and even aid attention deficit disorder.
Krill Oil or Fish Oil?
The experts say it doesn't really matter whether you choose fish oil or krill oil. While more research needs to be done on the benefits of krill oil, both oils are great sources of omega-3s. So long as you're including plenty of omega-3s in your diet, it doesn't matter where you source it.
And while supplements make it easy to take krill and fish oil, consider adding more fish to your diet. Nothing beats the real thing!
