In this paper we consider very weakly interacting and ultra light scalar and pseudoscalar dark matter candidates. We show that quantum gravity has important implications for such models and that the masses of the singlet scalar and pseudoscalar fields must be heavier than 3×10-3 eV. However, if they are gauged, their masses could be much lighter and as light as 10-22eV. The existence of new gauge forces in the dark matter sector can thus be probed by atomic clocks or quantum sensors experiments.
