We investigate the different energy conditions in non-local gravity, which is obtained by adding an arbitrary function of d'Alembertian operator, f(square(-1)), to the Hilbert-Einstein action. We analyze the validity of four different energy conditions and illustrate the different constraints over parameters of the power-law solution as well as de Sitter solution.
