Whey protein is one of the best sources of branched-chain amino acids (BCAAs), which are essential for muscle protein synthesis. It has eight times more BCAAs than casein protein. That’s why whey is such a great source of protein. Whey protein isolate is known as the “protein of choice” for athletes because it is cost-effective and high quality. It also contains other beneficial ingredients that make it even more perfect for muscle growth and recovery. So let’s look at some of the best whey protein isolates out there!
