What is fish oil?

The omega-3 fatty acids in fish oil include essential eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). It has been shown that fatty acids regulate several biological processes in the body. This includes controlling inflammation, metabolic signaling pathways, and brain functioning. 

Fish oil is known to be derived from fatty fish, such as salmon, tuna, and mackerel. In addition, fish oil can be derived from animals and phytoplankton. EPA and DHA are essential fatty acids synthesized by the body from alpha-linolenic acid (ALA), but the conversion rate is typically low. As a result, dietary sources such as fish oil are a significant way to obtain these vital fatty acids.
