Finnish scientists may have discovered exactly how a protein-packed beverage helps you build more muscle.
In a recent study, the researchers determined that weight lifters who drank a protein shake just before and just after their workout produced more of a molecule called cyclin-dependent kinase 2, or cdk2, than those who consumed a placebo did.
“Cdk2 signals your muscles to produce more stem cells, which aid in the process of building muscle and improve your body’s ability to heal after resistance training,” says study author Juha Hulmi, Ph.D.
In this study, the protein-shake drinkers downed 15 grams of whey protein immediately before and immediately after hitting the weights.
