A minimum daily protein intake of ≥1.6 g/kg is necessary to observe significant improvements in muscle mass from whey protein supplementation.
Athletes should ensure their total protein intake meets or exceeds 1.6 g/kg for optimal muscle gain.
StrongSupportsmedium confidence
Nonetheless, the observed improvements are minimized when the total daily protein intake reaches a minimum of ≥1.6 g/kg.
Why this rating
Based on studies conducted on humans.
