What You Need To Know About Optimum Nutrition Creatine

Optimum Nutrition Creatine: Power, Endurance & Mental Performance

Creatine is among the most extensively studied sports supplements, known for its ability to support muscular strength, recovery, and high-intensity performance. Recently, it has also gained recognition for its potential role in supporting brain function and cognitive resilience.

Optimum Nutrition (ON) offers premium-grade, banned substance-tested creatine formulas trusted by athletes worldwide. At Nutrition Warehouse New Zealand, you’ll find ON creatine options designed to fuel both physical training and mental sharpness.

Explore the Optimum Nutrition Creatine Range

Micronised Creatine Powder
A pure, unflavoured creatine monohydrate delivering 5 g per serve. Micronised for quicker mixing and absorption, this formula contains zero fillers, carbs, or sugars—making it ideal for stacking with your favourite protein, amino acids, or pre-workout blends.

Why Creatine Is a Go-To for Athletes and Lifters

Strength & Muscle Recovery
Creatine helps restore ATP, the body's quick-release energy source used during weightlifting, sprinting, and explosive movements.

Cognitive Function
Emerging research suggests creatine may support brain energy metabolism, improving mental clarity, focus, and performance under stress.

Long-Term Wellness
Reviews also point to creatine’s role in supporting neurological and cellular health, which may aid in long-term energy balance and cognitive maintenance (MedTech News, 2023; Business Insider, 2025).

Take Your ON Stack Further

Creatine works well as a base supplement—but its benefits multiply when combined with other Optimum Nutrition products:

  • Protein Powders – Gold Standard Whey, Isolate, and Casein for lean muscle support and recovery

  • Pre-Workouts – Gold Standard Pre-Workout to boost energy, focus, and intensity

  • Amino Acids – Products like Essential Amino Energy and BCAA Boost for endurance and hydration

  • Mass Gainers – High-calorie blends such as Serious Mass to meet growth and bulking needs
