Dosage Recommendations
General recommendation: 20-40g per serving, 1-3 times daily to meet total protein goals
Timing: Within a few hours of resistance training for optimal MPS; total daily intake matters more than precise timing
Dosage by Condition
Muscle building
20-40g post-workout + as needed to reach 1.6-2.2g/kg/dayStrong
Recovery
20-25g within 2 hours post-exerciseStrong
Weight management
25-50g per day as meal replacement or snackModerate
Sarcopenia prevention
30-40g per serving (older adults need higher leucine threshold)Moderate
General health
20-25g per serving, 1-2 times dailyStrong
