Omega-3s are a family of essential fatty acids that play important roles in your body and may provide a number of health benefits. As your body cannot produce them on its own, you must get them from your diet.
The three most important types are ALA (alpha-linolenic acid), DHA (docosahexaenoic acid), and EPA (eicosapentaenoic acid). ALA is mainly found in plants, while DHA and EPA occur mostly in animal foods and algae.
Omega-3 fatty acids play several important roles in your body. They have anti-inflammatory effects and are an essential component of your brain and eyes.
