'omega-3-associated' originates from the combination of 'omega-3', a type of polyunsaturated fatty acid, and 'associated', meaning connected or related.

The term 'omega-3' was derived from the Greek letter 'omega' (ω), indicating the position of the first double bond in the fatty acid chain, and '3' indicating its position from the methyl end of the chain. 'Associated' comes from the Latin 'associatus', meaning 'joined with'.

Initially, 'omega-3' referred specifically to the chemical structure of the fatty acid, but over time it has come to be associated with health benefits.
