Whey Protein


What is it? Whey protein is the protein from whey, the watery portion of milk that separates from the curds when making cheese. It is commonly used as a protein supplement.

Whey protein might improve the nutrient content of the diet and also have effects on the immune system.

People commonly use whey protein for improving athletic performance and increasing strength. Whey protein is also used for asthma, diabetes, weight loss, and many other conditions, but there is no good scientific evidence to support most of these uses.
