Optimum Nutrition Gold Standard 100% Whey is currently the most popular whey protein in America. It is a whey protein blend consisting of whey protein isolate, whey protein concentrate and whey peptides. It is sweetened with the artificial sweeteners sucralose and acesulfame potassium.
What the label doesn’t tell you, and it is with almost all American protein powders, is that they might contain rBGH (or rBST), a hormone the dairy farmers inject into the cows for added milk production. This hormone is banned in all of Europe, Canada, Australia and New Zealand. The US did not ban it. We’re not saying that all American milk products contain rBGH. Ben & Jerry ice cream for example refuse to use milk with rBGH. Unless it is specifically stated on the product label otherwise, you should assume all American protein powders to contain rBGH.
