Some studies suggest that protein supplementation after a workout can significantly increase muscle protein synthesis and reduce protein breakdown, while other studies indicate that the timing of protein intake (pre- or post-workout) does not further augment muscle mass or strength gains if adequate dietary protein is consumed.

The role of protein supplementation in muscle building, particularly when consumed post-workout, has been a topic of extensive research. This synthesis aims to consolidate findings from multiple studies to determine whether taking protein after a workout helps build muscle.
Enhanced Muscle Protein Synthesis and Muscle Mass:
No Significant Additional Benefits in Elderly Men:
Pre- vs. Post-Exercise Protein Intake:
Whole Foods vs. Isolated Protein Sources:
Combination with Carbohydrates:
Consuming protein after a workout can help build muscle by enhancing muscle protein synthesis and reducing protein breakdown. However, the timing of protein intake (pre- or post-exercise) appears to be flexible, and whole food sources of protein can be as effective as isolated protein supplements. Additionally, combining protein with high-glycemic carbohydrates post-exercise can further enhance muscle formation. For elderly individuals who already consume adequate dietary protein, additional timed protein supplementation may not provide significant extra benefits.
