'omega-3-related' originates from the term 'omega-3', which refers to a type of polyunsaturated fatty acid, combined with the suffix '-related', indicating association or connection.

The term 'omega-3' was adopted into English from scientific nomenclature, and 'related' is derived from the Latin 'relatus', meaning 'brought back'.

Initially, 'omega-3' referred specifically to the chemical structure of the fatty acids, but it has come to encompass health benefits associated with these acids.
