I briefly review the physics case for supersymmetric grand unified theories, which are a well-established and popular scenario for New Physics. Then I show that decays of B mesons are an excellent tool to study such theories, with the potential to provide evidence of physics beyond the Standard Model of Elementary Particles. I discuss the rare decay B_s -> mu^+ mu^- and point out correlations with particle searches at the Tevatron collider, the anomalous magnetic moment of the muon and the mass of the lightest Higgs boson. I further present new results on B-B-bar mixing.
