What is Whey protein?
Whey protein is a high-quality protein derived from milk during the cheese-making process. It is separated from the liquid part of milk after the milk is curdled and strained. The resulting whey is then dried to create a powder that is used in various food products and supplements.
Whey protein is popular for its high levels of essential amino acids and its role in supporting muscle growth and repair. It is often used in dietary supplements, protein bars, and meal replacements. While it is considered a complete protein, some people may be lactose intolerant or allergic to it.
When you see whey protein on a label, it indicates the product contains additional protein, often to enhance its nutritional content, especially in fitness and health-related products.
