New from Optimum Nutrition!

Gold Standard 100% Whey Isolate

  • 25g of Pure Whey Protein Isolate
  • 4.4g of Naturally Occurring BCAAs
  • 1g of Carbohydrates

Optimum Nutrition rejects more whey protein than some companies sell in a year. Every batch is manufactured & tested at their state-of-the-art registered NSF GMP for Sport facilities.

Uncompromising Quality

Optimum Nutrition tests every product at different stages of production to verify precise specifications. This hard work assures superior quality, so you can focus on achieving ambitious performance goals.

Starting with only the highest quality whey protein—filtered to isolate out excess fat, cholesterol, and sugar—a portion is hydrolyzed into smaller chains of amino acids.

The result is a fast-digesting complete protein containing no more than 1g of carbs, less than 1g of fat, and more than 80% of pure protein per serving.
