What It Is ⌄

Gold Standard 100% Isolate is Optimum Nutrition’s ultra-filtered whey isolate formula, built around whey protein isolate and hydrolysed whey isolate for a cleaner, lighter protein profile.

  • 25g high-quality whey isolate protein per serving.
  • 5.5g naturally occurring BCAAs per serving.
  • Very low sugars and fats in current product panels.
  • 31 servings per 930g tub in the current EU format.
  • Gluten-free formula in current product and official highlights.
Why It Stands Out ⌄

This formula stands out because it combines isolate purity with the kind of reliability and mixability Optimum Nutrition is known for. It is clean enough for leaner phases, but still easy to use every day without feeling clinical or under-dosed.

  • 25g protein per 30g serving for strong recovery support.
  • 5.5g naturally occurring BCAAs from the whey isolate base.
  • Very low sugars and fats for a tighter macro profile.
  • Hydrolysed and ultra-filtered isolate blend for a lighter feel.
  • 31-serving tub for a clean, premium everyday setup.

Why It Works ⌄

The formula logic is simple: keep protein purity high, keep the profile lean, and make the shake feel premium and easy to use. Protein contributes to the growth and maintenance of muscle mass, and the isolate-led design helps keep every serving focused on recovery rather than unnecessary extras.
