Essential Fatty Acids (EFAs) are long chain, polyunsaturated fatty acids which cannot be produced in the body so you must get them through diet. Omega 3's and 6's are responsible for many functions in the body like hormone production, regulation of the blood, support healthy skin and hair, increase brain function and cell reproduction.
The latest craze in Australia is using Krill oil instead of cod liver oil capsules. Are there any extra benefits making the switch from cod to krill? Well, krill oil has been around for a couple of years but as the health industry grows there is more interest in health products like this. There is potential that these capsules are absorbed easier and contain a powerful antioxidant called astaxanthin which protects your cells from free radicals. Other benefits of using krill is the positive effects it has on your heart, skin and the reduction in diseases.
There is still research to be done into krill oil to see if it actually is better for you than cod liver oil, however if you go to Australia it will all be about krill and you won't be supplementing on anything different ;)
