Eicosapentaenoic Acid (EPA) is an omega-3 fatty acid primarily found in fatty fish, such as salmon and mackerel. It plays a crucial role in human health, contributing to heart health by reducing inflammation and lowering triglyceride levels in the blood. EPA is also important for brain function and may support mental health by potentially alleviating symptoms of depression and anxiety. It is often consumed through fish oil supplements or by eating fish, making it accessible for those looking to improve their overall well-being.
