What are the different forms of whey protein and their characteristics?
Whey protein comes in three primary forms: concentrate, isolate, and hydrolysate. Concentrate contains 70–80% protein and includes some lactose and fat, making it the most economical option. Isolate boasts over 90% protein with minimal lactose, suitable for lactose-sensitive individuals, while hydrolysate is pre-digested for marginally faster absorption, though it comes at a premium price with minimal functional advantages.
