We construct the energy conditions for the recently proposed f(R, L, T) gravity theory, for which f is a generic function of the Ricci scalar R, matter Lagrangian density L and trace of the energy-momentum tensor T. We analyze two different forms for the f(R, L, T) function within the framework of the Friedmann-Lemâitre-Robertson-Walker universe. We constrain the model parameters from the energy conditions. This approach allows us to assess the feasibility of specific forms of the f(R, L, T) gravity.
