IntroductionThe relation between docosahexaenoic (DHA) and eicosapentaenoic (EPA) vs. arachidonic acid (AA) seems characterized by both synergism and antagonism.Materials and methodsInvestigate the relation between EPA+DHA and AA in populations with a wide range of EPA+DHA status and across the life cycle. EPA+DHA and AA were determined in erythrocytes (RBC; n=1979), umbilical arteries (UA; n=789) and umbilical veins (UV; n=785).ResultsIn all compartments, notably RBC, the relation between EPA+DHA and AA appeared bell-shaped. Populations with low RBC-EPA+DHA (<2 g%) exhibited positive relationships; those with high RBC-EPA+DHA (>8 g%) negative relationships. Antagonism in UA and UV could not be demonstrated.ConclusionBoth synergism and antagonism might aim at a balance between ω6 and ω3 long-chain polyunsaturated fatty acid (LCP) to maintain homeostasis. Synergism might be a feature of low LCPω3 status. AA becomes suppressed by antagonism from an RBC-EPA+DHA >8 g%.
► The relation between the ω3-index and AA status was investigated.
► The ω3-index and AA relate synergistically at low ω3 status.
► The ω3-index and AA relate antagonistically at high ω3 status.
► Synergism and antagonism might aim at a ω3/ω6 balance to maintain homeostasis.
