AB  - We investigate the non-relativistic limit of spherically symmetric boson stars in (4+1)-dimensional general relativity (GR). In this limit, the resulting Newtonian theory exhibits an exact scale invariance, leading to a critical boson star configuration with a fixed global U(1) charge and vanishing binding energy. We identify the origin of these properties in the restored scale symmetry and analyze how relativistic and gravitational corrections break this symmetry. By comparing the full (4+1)-dimensional Einstein-Klein-Gordon system with the Wick-Cutkosky model, we quantify the effects of these corrections on the energy-charge relation and the kinematic stability of the configurations. Our results demonstrate how weak violation of scale invariance lifts the degeneracy of the non-relativistic solutions and determines the behavior of boson stars away from the critical limit.
