In the past few years, the Minimal Flavor Violation (MFV) hypothesis has emerged as an appealing framework, allowing to reconcile the ever more constraining low-energy data with the possibility of New Physics below the TeV scale. In this talk, after a brief introduction, several aspects of its implementation are reviewed. First, CP violation in the MFV framework is revisited, showing that new phases are unavoidable. Second, if MFV is assumed to hold already at the GUT scale, its evolution exhibits IR fixed-points, translating as definite predictions for flavor-violating observables. Finally, enforcing MFV on baryon and lepton number violating interactions is shown to be sufficient to prevent a too fast proton decay. MFV is thus a viable alternative to R-parity, opening the door to additional channels for discovering supersymmetry at colliders.
