Liquid Fish Oil is a product category that contains select fish oils. These are characterized by a high content of omega-3 fatty acids, which are also known as very important healthy fats. They contain the eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), which are essential for the overall health of our body. This is mainly because they contribute to a proper heart function. On top of that, DHA also helps maintain proper brain functions and good eyesight. Our bodies cannot synthesize these healthy fats on their own in sufficient quantities. Therefore, it is of utmost important to include foods that contain them in our diet or supply them via dietary supplements.
