How to Get Fish Oil

Fish oil contains omega-3 fatty acids, which are essential fatty acids that you can only obtain from your diet. These acids are found naturally in fatty and oily fish, such as tuna, salmon and halibut. Omega-3 fatty acids are important for brain function, growth and development. Consuming fish oil may also help to reduce the risk of certain chronic diseases, such as cardiovascular diseases, cancer and arthritis. Although you can obtain omega-3 fatty acids from consuming some types of fish, you can also take a fish oil supplement.
