Optimum Nutrition Gold Standard 100% Isolate – Ultra-Pure Whey Protein

Gold Standard 100% Isolate is Optimum Nutrition’s most advanced whey protein formula — crafted for those who demand precision, purity, and performance. Through a multi-step filtration and hydrolysis process, this protein isolate delivers over 80% pure protein per serving, with minimal fat, carbs, or sugar. Whether you're targeting lean muscle development, post-workout recovery, or a low-lactose solution, this formula supports your goals without compromise.

 

Key Features

  • Rapid Protein Delivery for Muscle Repair: Provides fast-absorbing, complete protein to support muscle repair and maintenance. Hydrolysed for improved digestion and rapid uptake.
  • Low Carb, Low Fat: Each serve contains no more than 1g of carbohydrates and less than 0.5g of fat — ideal for lean physique goals or low-calorie diets.
  • Supports Muscle Recovery with Naturally Occurring Amino Acids: Delivers 5.5g of BCAAs, 4.3g of glutamine and glutamic acid, and 11.4g of essential amino acids to support muscle recovery and training demands.
  • Enhanced Digestibility Through Precision Filtration: Whey is filtered to isolate out excess fat, cholesterol, and sugar, then partially hydrolysed to break protein into smaller peptides for easier digestion.
  • Tested for Sport & Gluten-Free: Informed Choice certified and gluten-free, making it a reliable choice for athletes and dietary-sensitive individuals.

Hands down.. the best in the game!

I have been using ON protein for years - the taste, texture and the ease in mixing (and results gained) are just right up there.
Love the range of flavors and the subtle taste.
