We study natural supersymmetric scenarios with light right-handed neutrinosuperfields, and consider the possibility of having either a neutrino or asneutrino as a dark matter candidate. For the former, we evaluate thepossibility of having SUSY corrections on the $\nu_4\to\nu_\ell\gamma$ decayrate, such that the NuStar bounds are relaxed. We find that corrections are toosmall. For sneutrino dark matter, we consider thermal and non-thermalproduction, taking into account freeze-out, freeze-in and super-WIMPmechanisms. For the non-thermal case, we find that the $\tilde\nu_R$ canreproduce the observed relic density by adjusting the R-sneutrino mass andYukawa couplings. For the thermal case, we find the need to extend the model inorder to enhance sneutrino annihilations, which we exemplify in a model with anextended gauge symmetry.
