Inspired Nutraceuticals ISO is a premium, ultra-pure 100% whey protein isolate engineered to accelerate post-workout muscle repair, enhance lean muscle development, and satisfy your sweet cravings without excess calories. Formulated for athletes, bodybuilders, and active Kiwis demanding the highest standard of daily nutrition, this rapid-digesting isolate delivers maximum protein purity with virtually zero fats, sugars, or carbohydrates.

Key Benefits & Features

• 100% Pure Whey Isolate: Ultra-filtered WPI yielding exceptionally high protein content per scoop to optimise muscle protein synthesis.

• Rapid Nutrient Absorption: Fast-digesting protein fractions flood recovering muscle fibres with essential amino acids immediately post-exercise.

• Enhanced with Digestive Enzymes: Fortified with DigeZyme® to eliminate bloating, improve gut comfort, and maximise amino acid uptake.

• Exceptionally Lean Macro Profile: Virtually zero fat, minimal carbohydrates, and zero added sugars make it ideal for strict calorie deficits or lean bulking.

• Gourmet Bakery Flavour: Blends into an irresistibly rich, decadent shake that completely redefines the standard for lean protein powders.

How It Works

Through advanced cross-flow micro-filtration, Inspired ISO removes the vast majority of naturally occurring fats, cholesterol, and lactose found in whole dairy, leaving behind pristine, bioavailable whey protein isolate. This ultra-refined protein is rich in naturally occurring branched-chain amino acids (BCAAs) and essential amino acids (EAAs), which are critical for repairing microscopic muscle tears caused by intense resistance training.

To ensure your body makes full use of every gramme, Inspired ISO integrates the patented multi-enzyme complex DigeZyme®. These specialised enzymes assist in breaking down proteins into free-form peptides quickly and effortlessly, ensuring rapid gastric transit without the sluggishness, gas, or heavy digestive burden often associated with lesser protein powders.

Recommended Use

Mix 1 level scoop into 200–250ml of cold water or your choice of milk in your Sprint Fit shaker. Shake vigorously for 15–20 seconds until smooth. Consume immediately post-workout to kickstart muscle recovery, or use between meals throughout the day to meet your daily dietary protein targets.
