Iowhey Protein Isolate

Whey protein isolate is a highly purified form of whey protein, a byproduct of cheese production. It is made by further processing whey to remove most of the fat and lactose, resulting in a powder that is at least 90% protein by weight.

Manufacturers add whey protein isolate to foods to boost their protein content. It is commonly found in protein powders, bars, and ready-to-drink beverages, as well as in some baked goods and cereals, where it can also contribute to texture.

Whey protein isolate is generally recognized as safe (GRAS) by the FDA for use in food. It is a complete protein, containing all essential amino acids, and is readily absorbed by the body. Regulatory bodies like JECFA and EFSA have evaluated whey proteins. While generally considered safe and beneficial for muscle health and satiety, some individuals may experience digestive discomfort.
