Jay Robb uses the highest grade of whey protein possible when creating the best-tasting whey protein powder. This unique process also yields a whey protein isolate that is much higher in protein than a whey protein concentrate and is also rich in immunoglobulins, alpha-lactalbumin, and beta-lactoalbumin and other immune boosting factors. Jay Robb Non-GMO Whey Protein Isolate powders are made from the finest natural ingredients available and delivers 25 grams of first class protein, 0-fat, 0-cholesterol, 0-sugars, and only 1 gram of carbohydrate per 30 gram serving. Only cold-processed cross-flow microfiltered whey protein isolate is used as the protein source and this material comes from farm-raised, pasture-grazed, grass-fed cows not treated with the synthetic bovine growth hormone rBGH*. One taste of our easy-to-mix delicious Jay Robb Non-GMO Whey Protein Isolate powders, and you’ll be a fan for life! *Because rBGH-free whey is primarily obtained from small farms throughout the world, there is only a limited supply. The Jay Robb Corporation secures large quantities abroad each year to meet our growing needs; however, there are times when the world supply runs short. During these periods, we may choose to procure the highest quality domestic whey protein in conjunction with rBGH-free raw materials to produce our world-class whey protein.
