To create GOLD STANDARD 100% ISOLATE, they start by selecting only the highest quality whey protein which undergoes a series of sophisticated filtration processes to ‘isolate’ out excess fat, cholesterol and sugar. A portion of this Whey Protein Isolate is then hydrolyzed – broken down into smaller chains of amino acids – for easier digestion. The final product is a fast-digesting complete protein containing no more than 1 gram of carbohydrates, less than 1 gram of fat and more than 80% pure protein per serving. Optimum Nutrition put in the hard work to assure super quality, so you can focus on achieving ambitious performance goals.
