Protein shakes are for ensuring adequate protein intake, it just so happens that the protein requirements associated with strength/hypertrophy training are significantly higher than the protein requirements associated with other forms of training. So no, protein shakes aren't exclusively for those looking to build muscle/strength and nor will they magically make you build muscle.
