Deciding to have a protein shake before or after workout has long been debated among coaches and athletes. The age-old belief centers around a “golden hour” post-exercise, suggesting it’s the prime time for your muscles to soak up all the protein goodness. But how much truth is there to this? A recent study offers clarity, revealing that the timing of your protein shake, whether before or after exercise, might not be as crucial as once believed.

What Exactly is the “Golden Hour”?
Often dubbed the magic period post-exercise, the “golden hour” is when many believe our bodies are most eager to absorb protein, maximizing muscle growth. The common advice? Grab that protein shake within an hour of finishing your workout.

What Did the Study Find?
Some smart scientists in the study wanted to see if this “golden hour” was real. They asked a group of guys who work out regularly to drink a protein shake before or after workout.

Here’s what they found out:

  • The timing of the protein shake before or after workout didn’t significantly alter the results. The participants’ muscles developed and strengthened similarly.
  • This suggests that the “golden hour” might not be as rigid as previously assumed.
