Who buys it, and why
Whey isolate protein powder refers to protein powder made from whey filtered to remove most fat and lactose, giving a higher protein share per scoop than whey concentrate. People search it to compare brands, flavours, protein per serving, price and lactose content. In practice, buyers are gym-goers, athletes, people with mild lactose sensitivity and anyone raising protein intake, including GLP-1 users. Protein demand keeps growing across mainstream shoppers. The category is crowded, so angles are niche flavours, clean labels, subscriptions and comparison content.
