Fish oil contains vital fatty acids known as Omega-3 polyunsaturated fatty acids, in particular, eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). These fatty acids are known as “essential fatty acids”, which means that our bodies can’t manufacture them so we have to obtain them from our diet. 

The best source of Omega-3 fatty acids is oily fish such as salmon, sardines, mackerel and tuna. But we’d have to ensure we ate the recommended two to three serves of oily fish every week – can you be sure your intake is high enough?.
It’s no wonder that many of us turn to fish oil supplements to make sure our bodies get an adequate amount of these essential fatty acids.
