Beef protein is made from beef protein isolate and often consumed in powdered form as a protein supplement. It is low in carbohydrates and fat and high in protein and amino acids, including alanine, arginine, glycine, leucine, lysine, and proline.
In this randomized controlled trial, a beef patty increased muscle protein synthesis compared to a soy-based meat alternative patty but not compared to 2 soy-based meat alternative patties.
