Product Information



Isopure Unflavored WPI powder contains 26 grams per serving of unadulterated 100% Whey Protein Isolate, stripped of fat, carbs, fillers, sugars and lactose. Easy to add to any food and beverage (hot or cold), and so pure you won’t even taste it.

That’s what we’re made of. It’s also what we stand for—protein that’s lactose-free, low calorie, with little or no fat and carbs, and no impurities. The purest stuff out there. Not to mention delicious. Beyond quality. This is protein with taste.
Pack in powerfully pure protein, without packing on the carbs. Our 100% whey protein isolate powders amp you up, without any unwanted weight. Just pick your level: Zero Carb or Low-Carb (which also has ZERO sugar), both with 25 grams of protein per scoop. It's 100% whey protein isolate loaded with vitamins, minerals and nutrients to keep you going strong—and always without gluten, lactose, or any impurities. Made with our complete microfiltration process to be the only completely clear milk protein when dissolved in water. Available in a range of delicious flavors to mix up some seriously delicious and dynamic recipes. Note: Zero/Low Carb Isopure powders have a vitamin/mineral premix which is not soluble; they will be cloudy when dissolved.


Add one rounded scoop of Isopure unflavored whey protein isolate to any of your favorite foods to increase your daily quality protein consumption. Isopure mixes with a spoon and is easily added to hot food, cold food or beverages. Drink one serving daily.
This product is produced in a facility with soy, dairy, egg and wheat ingredients, peanuts and tree nuts.

Unflavored stuff
I really enjoy the unflavored version of Isopure. It doesn't have any aftertaste, dissolves quickly and completely. If I want to add a flavor, I can pick one that I like and add it manually.
I recommend the unflavored, it is versatile.

Different Than Any Other Powder/Shake
I'm sure the benefits are incredibly similar to the other Isopure, etc. whey protein powders but the real difference is in the consistency. The Natural Isopure is a lighter, more liquid consistency than any other shake I've had. It's more like drinking a clear liquid than a thick shake. And it tastes great. Not super sweet, not watered down, just right. It blends well even with a glass and spoon although I still prefer a shaker. It packs a great 50g per serving with only 6 carbs & 1 fat. I often just do half a serving at points in the day. It isn't a filling product so you don't feel like you're going to explode after you drink even a full serving. It's kind of costly but some things are worth the cost. I love Isopure's clear liquid bottled proteins and this is a nice, simple (& cheaper) addition/alternative. I definitely recommend trying it.
