Timing & Absorption Engine
Timing & Absorption
When you eat protein matters. Plan meals around the leucine threshold, your workout and your sleep.
Post-workout
High-quality protein within ~2 hours after training supports repair and growth.
Leucine per meal
The “switch” that maximally triggers muscle protein synthesis (MPS).
Per meal × 4
Spreading protein evenly across ~4 meals beats one big dinner.
Pre-sleep casein
A slow protein 30–60 minutes before bed feeds overnight recovery.

Enter your target and routine. We’ll space your meals, place your post-workout feed and pre-sleep protein.
Digestion speed
Fast after training. Slow before sleep.
Fast proteins spike amino acids in the blood quickly, which helps after workouts. Slow proteins release amino acids for hours, which helps between meals and overnight.
“30 g is the limit per meal.” Absorption is steady (~5–10 g/hour) and nearly complete. Total daily intake matters most.
