DHA, or docosahexaenoic acid, is an omega-3 fatty acid that is crucial for brain health and development. It is primarily found in fatty fish, such as salmon and mackerel, as well as in algae. DHA plays a significant role in the structure of brain cell membranes and is important for cognitive function, vision, and overall neurological health. In addition to its benefits for brain health, DHA is also essential during pregnancy and early childhood. It supports the development of the fetal brain and may contribute to better cognitive outcomes in children. Many people choose to supplement their diets with DHA through fish oil or algae-based supplements to ensure they receive adequate amounts.
