Protein, By Goal
Grams per kg body weight per day
Summary
The 0.8 g/kg RDA prevents deficiency; it is not optimal. Performance, recomposition, and aging each shift the target upward.
Takeaway
Above ~1.6 g/kg, muscle protein synthesis plateaus in most adults; older adults benefit from the higher end.
