Fish oil is a dietary supplement derived from the tissues of oily fish. It is rich in omega-3 fatty acids, primarily eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), which are essential nutrients that play a crucial role in maintaining heart health, brain function, and overall well-being. Fish oil is often taken to support cardiovascular health by helping to reduce triglyceride levels, lower blood pressure, and decrease the risk of heart disease. It is also known for its anti-inflammatory properties, which can benefit individuals with conditions such as arthritis. Additionally, fish oil is believed to support cognitive function and may contribute to the maintenance of healthy skin. It is available in various forms, including capsules, liquid, and as an ingredient in fortified foods. Regular consumption of fish oil, under the guidance of a healthcare professional, can be a valuable addition to a balanced diet.
