Who buys it, and why
Whey protein refers to protein powder made from whey, the liquid left after cheese making, sold as concentrate, isolate and hydrolysate in many flavours. People search it to compare brands, prices, protein per serving and taste, and to learn when to take it. In practice, gym-goers, people losing weight and older adults aiming to eat more protein drive the searches. Demand has grown with high-protein diets and GLP-1 users protecting muscle. Clean-label, flavour-led and single-serve formats give brands room in a large, repeat-purchase category.
