How to Use the Post-Workout Protein Timing Guide
Enter your body weight, workout type, intensity, and whether you ate before training. The calculator provides your recommended post-workout protein serving, optimal timing window, and daily protein target.
The strict 30-minute "anabolic window" is largely overstated. If you had protein before your workout, the post-workout window extends to 2–3 hours. What matters most is your total daily protein intake of 0.7–1g per pound of body weight. Distribute protein across 4–5 meals throughout the day for best results. Post-workout protein is important, but it's one piece of the nutrition puzzle.
Frequently Asked Questions
Not necessarily for muscle growth. Shakes are convenient and absorb faster, but whole food protein (chicken, eggs, Greek yogurt) is equally effective if consumed within the timing window.
Recent research suggests the body can efficiently use 40–60g per meal — more than the old "25g limit" myth. Larger servings aren't wasted, just absorbed more slowly.
Yes — pre-workout protein (1–2 hours before) reduces muscle breakdown during training and extends the post-workout anabolic window, making exact post-workout timing less critical.
