What are Omega 3 fatty acids?

Omega 3 fatty acids are nutrients that help you build and maintain a healthy body. They help keep the heart, lungs, blood vessels, and immune system healthy. They’re important to the structure of every cell wall. They are also an energy source.

There are three main omega-3 fatty acids are alpha-linolenic acid (ALA), eicosapentaenoic acid (EPA), and docosahexaenoic acid (DHA). ALA is found mainly in plant oils such as flaxseed, soybean, and canola oils. EPA and DHA are primarily found in certain fish.

DHA levels are especially high in retina, brain, and sperm cells.
