What is Whey Protein?

Whey protein powders are the most common protein supplements and are used to build lean muscle mass. Whey is a by-product of cheese manufactured from cow's milk. Whey protein is a fast-digesting source of protein.

Whey protein usually comes in three types:

• Whey protein isolates are higher quality and are processed to remove the fat and lactose. They are 90%+ protein by weight.
• Whey protein concentrates contain low fat and cholesterol but are lower quality at 29%-89% protein by weight.
• Whey protein hydrolysates are predigested, partially hydrolyzed whey proteins that are more easily absorbed, but their cost is higher.

See the nutrition label of your product to see if it is a pure whey protein isolate, or if it has concentrates in it. We recommend a whey protein powder that has whey protein isolate as its first ingredient.
