Available in Strawberry Shortcake, Vanilla Milkshake and Chocolate Milkshake flavors, the drinks are designed to support both protein intake and post-workout recovery while eliminating the preparation required with traditional powders. For MET-Rx, the launch expands its established sports nutrition portfolio into a convenient format that can reach consumers beyond traditional gym settings.
