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's Whey Protein is 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.
