Docosahexaenoic acid (DHA) is an omega-3 fatty acid that is crucial for human health. It is primarily found in fatty fish, such as salmon and mackerel, as well as in algae. DHA plays a vital role in brain development and function, making it particularly important during pregnancy and early childhood. In addition to its benefits for brain health, DHA is also known to support heart health by reducing inflammation and lowering triglyceride levels. It is often included in dietary supplements and fortified foods to help individuals meet their omega-3 needs, especially for those who do not consume enough fish in their diet.
