Omega-3s are essential polyunsaturated fatty acids that your body can’t make itself, so you have to get them from your diet. They’re found naturally in fish oil — meaning it can be difficult to get enough of it from what you eat alone, if you don’t eat enough fish in your diet.
What is omega-3?
Omega-3s are a group of essential fatty acids that play numerous important roles in your body. They occur naturally in one of two forms, triglycerides or phospholipids. As your body cannot produce omega-3s on its own, these fatty acids must be sourced from your diet.
Three important omega-3 essential fatty acids include ALA (alpha-linoleic acid), EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid). DHA and EPA play a vital role in human physiology as they have benefits such as helping to support heart health.1
