Who searches for it, and why
Whey protein isolate refers to a filtered form of whey protein with more protein and less lactose, fat and carbohydrate than whey concentrate, sold as powders and ready-to-drink shakes. People search it to choose a product, compare brands, flavours and price per serving, and check whether it suits lactose-sensitive diets. In practice, buyers are gym-goers, athletes, people on weight-loss diets and those raising their daily protein. Protein has spread into everyday snacks and drinks. It is a large, repeat-purchase supplement category with room for new brands and formats.
Most people search it to buy or sign up.
