Docosahexaenoic acid (DHA) is another vital omega-3 fatty acid found in cold-water fish, and it's especially important for brain and eye development. It is a major structural component of the brain, retina, and other neural tissues, making it essential during pregnancy and early childhood. For adults, DHA supports cognitive function, helps maintain heart health, and may reduce inflammation throughout the body. It also plays a role in preserving vision and supporting healthy aging of the brain.

Omega-3 fatty acids, including EPA and DHA, are essential fats that the body cannot produce on its own, meaning they must be obtained through diet or supplements. They are widely known for their cardiovascular benefits, such as lowering high blood pressure, reducing triglyceride levels, slowing the buildup of plaque in the arteries, and decreasing the risk of heart attack and stroke. Omega-3s also support brain health, reduce inflammation, and may help improve symptoms of mood disorders, support eye health, and promote joint flexibility. Regular intake is associated with overall improved well-being and long-term health.
