The hypothesis that the physical neutrino is a Goldstone particle associated with spontaneously broken supersymmetry is studied with emphasis on the ensuing low-energy theorems. A picture of low-energy neutrino phenomenology is found which is attractive for neutral-current processes, but is in strong disagreement with experimental end-of-lepton-spectrum behavior in β decays.
