Whey protein shakeThe most common types of protein shakes are made from whey, a by-product of cheese. Whey-based proteins can be broken down into three main subcategories: Whey protein concentrate, isolate, and hydrolysate. Whey protein concentratePros: Concentrate is the cheapest option, it tends to mix the best in water and it tastes the best. It’s about 99% lactose-free, so for people who have a lactose problem, isolate protein is one they can normally tolerate. Whey protein hydrolysatePros: It’s been filtered through again, it’s pretty much 95% protein.
