Whey Protein Isolate 90

Whey protein isolate 90 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 lactose, fat, and other components, resulting in a powder that is at least 90% protein. This process typically involves filtration and drying.

Manufacturers add whey protein isolate 90 primarily as a protein source to boost the protein content of foods and beverages. It is commonly found in protein powders, bars, sports nutrition products, and sometimes in baked goods or dairy alternatives. Its neutral flavor and good solubility make it versatile.

Whey protein isolate 90 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 a popular supplement for muscle building and recovery. International bodies like JECFA have evaluated whey protein and its components. While generally considered safe, excessive protein intake can put a strain on the kidneys in individuals with pre-existing kidney conditions.
