Whey proteins are complete proteins that provide the essential aminos your body needs. It is rich in branched-chain amino acids (bcaas) and glutamine. But not all whey proteins are alike. Some are cleaner and purer than others. Gram for gram, these superior whey protein “isolates” (wpis) have more protein, less fat and carbs, than their counterparts, whey protein “concentrates” (wpcs). Ultra Iso Whey from Universal Nutrition contains only premium 100% ultrafiltrated whey protein isolates with zero carbs, zero sugar, zero fat, and zero lactose. While there are distinct differences between wpcs and wpis, there are also differences between different WPI products, and some whey protein isolate products are purer than others. With Ultra Iso Whey we don¹t add any gums, binders, fillers, and thickeners to weigh the shake down or interfere with the absorption of the protein. We also don¹t use any aspartame. And because we use only ultrafiltrated whey isolates, Ultra Iso Whey preserves many of the important biological fractions found in whey including immunoglobulins, lactoferrin, GMP, and BSA. With our Ultra Iso Whey, you get a full spectrum whey isolate protein shake that mixes easily with a spoon and goes down easy.
