What Is Whey Protein Derived From?

Whey protein has long been a way for bodybuilders, athletes and fitness enthusiasts to ingest whey protein. Whey protein has many benefits, including antioxidant properties and providing branched-chain amino acids necessary to build and retain muscle mass.

  1. How Whey Is Derived

    • Whey protein is produced from milk and is a by-product of cheese production. Most supplements sold in stores today come from cow's milk.

    Process

    • Cheese is produced by curdling and straining milk. Whey is the product that remains, and is separated from milk after curdling.

    Finished Product

    • After the whey is separated, it is often combined with artificial flavoring and sold in powder form as a nutritional supplement. There are two types of whey produced. Whey protein isolate is the most concentrated form and contains up to 90 percent protein and very little fat or lactose. Whey protein concentrate may contain anywhere from 20 to 89 percent protein and corresponding amounts of fat and lactose.

    Additional Sources

    • The first milk produced by a breastfeeding mom is nearly 100 percent whey and boasts immune-boosting properties. (While this is a different form than cow-produced whey, it offers similar health benefits.)

    Benefits

    • Whey protein isolate is considered a biologically "perfect" protein, meaning 100 percent of the protein is absorbed and used by the body.

    Forms

    • Whey protein can be incorporated into such foods as yogurt and energy bars as well as in drink form as ready-to-drink shakes, meal replacement powders and milk-based beverages.
