What it is

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 lactose and fat, resulting in a powder with a high protein concentration.

Why it's used

Manufacturers add whey protein isolate blends to foods to boost protein content. It is commonly found in protein powders, bars, and ready-to-drink beverages, often used in sports nutrition products for muscle recovery.

Health notes

Whey protein isolate is generally recognized as safe (GRAS) by the FDA when used as a food ingredient. It is a source of complete protein, providing all essential amino acids. The WHO and EFSA have evaluated whey proteins, and they are widely consumed without significant adverse effects at typical intake levels. Some individuals may experience digestive discomfort.

Allergen info

Whey protein isolate is derived from milk, which is one of the 9 FDA major allergens. It does not contain gluten.
