Muscle building unaffected by vegan or animal-based protein sources

A new study asked three questions about muscle protein synthesis in response to a nine-day diet and weight training regimen: First, does the source of protein - plant or animal-based - make any difference to muscle gain? Second, does it matter if total daily protein intake is evenly distributed throughout the day? And third, does a moderate but sufficient daily protein intake influence any of these variables? The answer to all three questions is "no," the researchers found.
