Whey protein powder is a high-quality protein supplement derived from milk during the cheese-making process. When milk is curdled and strained, it separates into curds and whey. The liquid whey is then processed and dried to create whey protein powder.
Whey protein is popular among athletes, bodybuilders, and fitness enthusiasts due to its excellent amino acid profile, which includes all nine essential amino acids. This makes it a complete protein source that is easily digested and absorbed by the body.
