Fish oil supplements provide a source of omega-3 fatty acids. They are derived from the tissues of oily fish. Omega-3 fatty acids are considered essential as the body cannot make them itself. The main health benefits associated with omega-3 fatty acids include supporting heart health, cognitive function and joint health.
Omega-3 fatty acids can also be beneficial for pregnant women and children as they contribute to the development of the brain, eyes and nerves in unborn babies and young children. The best dietary sources of omega-3 fatty acids are oily fish such as salmon, mackerel, herring, sardines, pilchards and fresh tuna. For vegetarians and vegans, flaxseed oil and chia seeds are a good source of omega-3 fatty acids.
