What is Whey Protein?

Whey protein is a high-quality protein derived from milk during the cheese-making process and is rich in essential amino acids. It is naturally found in dairy products and has become a staple in the nutrition and fitness worlds due to its impressive profile of branched-chain amino acids (BCAAs), particularly leucine, which plays a critical role in muscle protein synthesis. Research indicates that whey protein can support muscle growth, enhance recovery from exercise, and even aid in weight manag
