Fish oil is a popular dietary supplement that is derived from the tissues of oily fish, such as salmon, tuna, and mackerel. It is rich in omega-3 fatty acids, which have been linked to a variety of health benefits, including reduced inflammation, improved brain function, and lower risk of heart disease.
In particular, the omega-3s EPA and DHA have been shown to have important roles in supporting heart health by reducing triglyceride levels and improving blood pressure. While it is possible to obtain omega-3s from whole fish, fish oil supplements are a convenient and popular option, particularly for individuals who do not regularly consume fish in their diet.
However, it is important to note that fish oil supplements may interact with certain medications and should be taken under the guidance of a healthcare professional.
