100% Whey Isolate


Note: Chocolate Flavor has 3 carbs per serving.

NATURE'S BEST® PERFECT® ZERO CARB ISOPURE® contains 50 grams of 100% Whey Protein Isolate. Any and all impurities typically found in most whey proteins have been removed to provide you with a great tasting, lactose free, glutamine enriched, state of the art carbohydrate free protein supplement.

Nature's Best set out to create a product that didn't hide anything from its customers. We wanted you to know that you're purchasing the best product available on the market. Our protein source is clearly identified as 100% Whey Protein Isolate. We didn't try to confuse you by listing a protein blend that doesn't tell you how much of the product is superior whey protein isolate and how much is whey protein concentrate or sweet whey or some other inferior protein source.

Furthermore, ISOPURE contains 0 g of sugar and is instantized so it can be taken anywhere and mixed with a spoon.
ISOPURE's Major Proteins include:
Beta-lactoglobulin 55-62%
Alpha-lactalbumin 19-22%
Immunoglobulin 9-10%
Bovine Serum Albimin 6-8%
Lactoferrin .5-1%
In addition, ISOPURE is rich in branched chain amino acids and glutamine.
Each serving of ISOPURE Contains:
3465 mg of isoleucine
7865 mg of leucine
3080 mg of valine
4.6 g of L-Glutamine.

Athletes tend to need more protein than sedentary individuals to achieve positive nitrogen balance. Most recommendations range from 1.5 - 2.0 grams of protein per kilogram of body weight per day. Isopure will help you achieve the positive nitrogen state you are seeking.

It's So Pure The Protein Dissolves Clear.

In addition to dissolving clear, Isopure protein is also light and easy to drink. The protein used in PERFECT ISOPURE doesn't have the properties typically associated with a milk protein. It doesn't look, smell or taste like milk. We isolated the whey protein molecules and eliminated the impurities to provide you with the purest product of its kind.

You'll note when you mix ISOPURE powder the results are cloudy. This is due to the addition of valuable vitamins, minerals and flavorings. However, the proof is in our 20 oz ready-to-drink Zero Carb ISOPURE bottles. Please check out our selection of assorted flavors. The protein dissolves so clear you can see right through the bottle.


For a rich, thick shake, mix 2 scoopfuls (62g) with 12 fluid ounces of water in a shaker or blender. If a shaker or a blender is not convenient, Isopure can be stirred into solution with a spoon.
