Is Omega 3 the Same as Fish Oil? 

Omega 3 and Fish Oil are not the same.Omega-3 refers to a group of fatty acids with a double bond located three carbons away from the methyl end of the molecule. Fish oil, on the other hand, is a dietary supplement derived from the tissues of fatty fish, such as salmon, mackerel, and anchovies, which are rich sources of omega-3 fatty acids.

Omega-3 fatty acids are essential, meaning the body cannot produce them independently. There are three main types of omega-3 fatty acids: alpha-linolenic acid (ALA), eicosapentaenoic acid (EPA), and docosahexaenoic acid (DHA). 

While Fish oil is a popular way to increase omega-3 intake, other sources of omega-3 are worth considering and will be mentioned later in this article.
