Even though there are many different types of protein powders out there, I’ve always preferred plain old unflavored whey. Its creamy flavor and texture make it great not just for shakes but for other dairy-themed meals like yogurt parfaits. But another great protein powder has finally won me over, and it’s a weird one: clear whey.

It’s just what it sounds like: whey protein powder that is clear when it dissolves in water. The result is something that is more like drinking lemonade or juice than a creamy shake. It comes almost exclusively in fruity flavors that might remind you of an energy drink rather than a milkshake. That’s because the chemistry that allows the whey to be clear requires it to be in an acidic solution—and acid pairs well with fruity flavors. I’ve tried a peach-mango and a lemonade flavor from MyProtein; I've also heard of margarita and mojito flavors. This sour strips flavor from Ghost intrigues me.How does the nutrition compare?

Clear whey is still whey, so you’re still getting a good quality protein (with all nine essential amino acids) whether you choose the clear or regular variety. One difference, though, is that clear whey is made from whey isolate rather than concentrate. Whey isolate contains the proteins and almost nothing else, while whey concentrate is about 80% protein. The other 20% includes small amounts of fats and carbs. Thus, the nutritional content of clear whey is basically the same as a traditional (milky-appearing) whey isolate powder.Both isolates and concentrates are good choices if you’re looking to add a little protein to your diet. The “extra” fats and carbs in a whey concentrate only add about 20 calories per scoop, so they’re not going to make or break your diet. That said, if you’re lactose intolerant or find that whey powder sometimes upsets your stomach, an isolate like clear whey may agree with you a little better.
