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