Perfect For Low Fat Low Carb Diets. No Artificial Sweeteners or Colors!

Whey Protein Isolates are 90% pure protein by weight. They are one of the purest and most expensive form of whey protein that exists. That's why they are the first ingredients you read on the Gold Standard Natural 100% Whey label.


By using Whey Protein Isolates as our primary protein source, we're able to pack 24 grams of the purest, muscle-building protein per serving, with a lot less of the fat, cholesterol, lactose, and other stuff that you can do without.


There's no question this is the standard by which other whey proteins are measured.

Beyond The Basics

  • Free of artificial flavors, colors, and sweeteners.
  • Whey Isolates are the primary protein source
  • Higher Pure Protein Percentage
  • Fast-Acting HYDROWHEY™ Whey Peptides
  • Provides Whey Protein Microfractions
  • More than 5 grams of BCAAs
  • Over 4 grams of Glutamine & Precursors

  1. Quality
    Great flavor and no artificial sweetners
    If sweetness is what you want, keep searching. I don't want a protein powder that tastes like birthday cake, so having a subtly and naturally sweetened protein (mostly isolate) goes perfectly in a smoothie. I've had the regular Gold Standard and this natural one is slightly less sweet. Tip: add a scoop to 8oz cup off coffee... tastes just like vanilla creamer + 24g protein!

    Love this natural protein
    I mix this natural whey with my smoothies and I get a much creamier smoothie than I have ever gotten with any other protein. I use the strawberry and it adds great flavor... I love this is natural protein with out artificial sweetner-which is difficult to find.
  4. Quality
    First class protein powder.
    I used to use the Gold Standard Whey protein but realized it had artificial flavors and sweeteners, don't get me wrong, it's a top shelf protein but I decided I wanted the same effectiveness in a more natural product so I started buying 100% natural whey a few months ago .

    It is basically the same high quality as the Gold Standard but is naturally sweetened and flavored and still has a good taste.
    Some reviewers complained about the taste but if you want really sweet then go for the Gold Standard or some other brand with artificial ingredients. I'll be sticking with this one and the ON natural casein protein.

  6. Quality
    ON Makes Good Supps but.....
    ...if taste is important to you don't take this stuff. Its a good all around whey and its all natural but it tastes terrible. I mix my protien shakes with water so using milk would probably help.
