Protein Timing: What Actually Matters
The 30-minute anabolic window isn't what you've been told. Here's what the research actually says.
For two decades, the "anabolic window" — that 30-minute post-workout panic to slam a shake — has been gospel. The research now tells a different story.
What matters more than timing
- Total daily protein intake (1.6–2.2 g/kg bodyweight for training adults).
- Distribution across 3–5 meals.
- Per-meal leucine threshold (~2.5g) to maximally stimulate muscle protein synthesis.
If you ate a protein-rich meal 1–2 hours before training, the window stretches to 4–6 hours post-workout. Relax.
The exception
Fasted morning sessions are the one case where post-workout protein really does matter sooner rather than later. Otherwise — hit your daily total, spread it out, train hard.
