We consider mixed three-point correlation functions of the supercurrent and flavor current in three-dimensional 1≤N≤4 superconformal field theories. Our method is based on the decomposition of the relevant tensors into irreducible components to guarantee that all possible tensor structures are systematically taken into account. We show that only parity-even structures appear in the correlation functions. In addition to the previous results obtained in [E. I. Buchbinder J. High Energy Phys. 06 (2015) 138JHEPFG1029-847910.1007/JHEP06(2015)138], it follows that supersymmetry forbids parity-odd structures in three-point functions involving the supercurrent and flavor current multiplets.
