No. Fish oil is a source of docosahexaenoic acid (DHA) and other fatty acids like EPA. DHA is one specific compound within fish oil.
Yes. While fatty fish are the richest source, DHA is also produced by certain microalgae, and algae-based supplements are available.
DHA is a primary structural component of the brain and retina. Adequate intake during pregnancy and infancy supports optimal cognitive and visual development.
Both are omega-3s. DHA (22:6) is more concentrated in the brain and eyes and is crucial for structure. EPA (20:5) is more involved in inflammatory processes and heart health. They have overlapping but distinct biological roles.
