Quality Testing

In addition to testing each ingredient that arrives at our factory to verify precise specifications, Optimum Nutrition tests every product at different stages of production. This uncompromising commitment to quality assurance is what distinguishes us as a company.

Gold Standard 100% Isolate

To create GOLD STANDARD 100% ISOLATE™, we start by selecting only 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. The final product is a fast digesting complete protein containing no more than 1 gram of carbohydrates, zero grams of fat and more than 80% of pure protein per serving. We put in the hard work to assure superior quality, so you can focus on achieving ambitious performance goals.

Selecting Only The Best

OPTIMUM NUTRITION qualifies, tests, and re-tests every step of the way. After carefully selecting raw material suppliers, each ingredient is tested to assure exceptional purity, potency and composition. The effort then intensifies with Uncompromising Quality where each batch is tested before it leaves our factory. We use advanced applications to maintain standards so high, we reject more whey protein than some of our competitors sell in a year.

GOLD STANDARD 100% ISOLATE™ was formulated and developed at the OPTIMUM NUTRITION U.S. Research & Development Center and made in our own U.S. manufacturing facilities. Our top professionals in the industry put in long hours to set this new standard for delicious taste and high protein percentage per serving.
