100% Natural Whey Protein Isolate.
Pure Unflavored Protein, Zero Additives.

Nature's Best® Isopure® Unflavored Whey Protein Isolate contains 26 grams per serving, of pure, unadulterated 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, state of the art carbohydrate free protein supplement.

Nature's Best® Isopure® Unflavored Whey Protein Isolate is a convenient way to fortify your favorite foods.  You simply add Isopure Unflavored Whey Protein Isolate directly to hot food, cold food or beverages.  And since it is virtually tasteless, it is the perfect addition to your favorite recipes.  It is 100% Natural, and has no fat, carbs, sugars or lactose.  It has no fillers, no artificial flavors, and no artificial sweeteners.

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% Pure 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 Unflavored Whey Protein Isolate 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 Albumin 6-8%
Lactoferrin                      .5-1%

In addition, Isopure is rich in branched chain amino acids and glutamine.

Each Serving of Isopure contains:

1404mg of isoleucine
3094mg of leucine
1430mg of valine
2.57g 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 Unflavored Whey Protein Isolate will help you achieve the positive nitrogen state you are seeking.*

It's So Pure The Protein Dissolves Clear.
In addition to dissolving clear, Natural Isopure protein is also light and easy to drink.  The protein used in Isopure Unflavored Whey Protein Isolate 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.
