Description

Supercharge your physical performance and accelerate lean muscle gains with Optimum Nutrition Micronised Creatine Powder. Formulated with 100% pure creatine monohydrate, this gold-standard supplement rapidly replenishes your body's adenosine triphosphate (ATP) energy stores during heavy lifting and high-intensity interval training. Engineered using advanced micronisation technology, the powder particles are mechanically broken down to yield superior liquid suspension and maximum digestion. Whether your goal is breaking personal records, driving training intensity, or speeding up recovery, ON Micronised Creatine delivers an uncompromised foundation for serious athletes across New Zealand.

Key Benefits & Features

  • 100% Pure Creatine Monohydrate: Delivers a potent 5g serving of high-grade creatine per scoop to fuel explosive muscular endurance and athletic output.

  • Advanced Micronised Particle Structure: Refined formula dissolves easily in fluids without leaving behind gritty residue or heavy powder at the bottom of your shaker.

  • Maximises ATP Energy Production: Rapidly recycles cellular energy to increase heavy workout volume, push extra reps, and delay fatigue.

  • Supports Lean Muscle Growth: Helps increase intracellular hydration, driving enhanced nutrient delivery directly into target muscle tissue to support hypertrophy.

  • Versatile Unflavoured Formula: Stacks effortlessly into post-workout protein shakes, pre-workout formulas, or everyday hydration drinks with zero flavour crossover.

How It Works

Creatine monohydrate is one of the most thoroughly researched sports nutrition compounds on the market today. During demanding physical exertion, your muscles rely on intracellular ATP (adenosine triphosphate) for instantaneous power. As ATP depletion occurs, strength and explosive output naturally drop off. Supplementing daily with Optimum Nutrition Micronised Creatine saturates your muscle tissue stores, rapidly synthesizing phosphocreatine to replenish ATP supplies on demand.

The key distinction with ON Micronised Creatine lies in its processing. By drastically reducing the raw particle size compared to standard coarse powders, the overall surface area is expanded. This yields rapid absorption into the system while preventing stomach bloating or gastrointestinal discomfort often associated with lower-grade monohydrates.

Recommended Use

Mix 1 rounded teaspoon (5g) with 250–300ml of cold water, fruit juice, or your preferred post-workout protein shake. Stir or shake until fully dissolved.

  • Daily Consistency Phase: Consume 1 serving (5g) daily at a consistent time to maintain full tissue saturation, on both training and rest days.

  • Optional Loading Phase: To saturate muscle stores quickly, consume 20g daily (divided into four 5g doses throughout the day) for the first 5 days, followed by a standard 5g daily maintenance serving thereafter.

Optimum Nutrition Micronised Creatine Powder Frequently Asked Questions

What is the difference between standard creatine monohydrate and Optimum Nutrition Micronised Creatine?

While both products provide 100% pure creatine monohydrate, Optimum Nutrition Micronised Creatine has undergone an advanced mechanical milling process. This process refines the raw powder particles until they are up to 20 times smaller than standard creatine crystals. The smaller particle size dramatically increases surface area availability, offering two major performance benefits:

Superior Mixing: It dissolves rapidly and stays suspended in fluid significantly longer, completely eliminating the gritty texture or heavy sludge often left behind at the bottom of a shaker.

Gentle Digestion: The micro-pulverized structure is exceptionally easy for the digestive system to process, making it highly popular for trainers prone to mild stomach bloating or gastrointestinal discomfort from coarse powders.

How many servings are in the 300g, 600g, and 1.20kg container sizes?

Based on a scientifically standard daily maintenance serving size of 1 rounded teaspoon (5g), the exact volume yields available at Sprint Fit include:

300g Tub: Provides 57 full servings (ideal for testing out the pure unflavoured formula).

600g Tub: Provides 114 full servings (the perfect multi-month gym staple).

1.20kg Tub: Provides a massive 228 full servings (delivering the absolute best long-term cost-per-scoop value for dedicated trainers).

Do I need to follow a loading phase when taking this product?

No, a loading phase is entirely optional and depends strictly on your personal timeline goals:

The Fast-Track Loading Phase: Take 20g daily (divided into four independent 5g doses taken with meals) for 5 consecutive days to rapidly saturate your muscle tissue, then transition to a 5g daily maintenance serving.

The Steady Maintenance Phase: Skip the loading period completely and simply consume 1 rounded teaspoon (5g) every single day. Your system will reach peak baseline saturation within 3 to 4 weeks with zero loading required.

Should I take Optimum Nutrition Micronised Creatine Powder on rest days?

Yes. Creatine operates via continuous cellular accumulation over time rather than acting as an immediate, fast-acting stimulant. To ensure your muscle tissue energy stores remain completely saturated for ongoing daily power output and physical conditioning, you must consume a 5g serving every day, including non-training rest days.

Can I stack this unflavoured creatine with my pre-workout or protein shake?

Absolutely. Because it is 100% raw, unflavoured, and completely free from artificial fillers, chemical additives, or sugars, it blends seamlessly into any beverage. You can easily stir or shake 5g into cold water, juice, your favorite pre-workout, or an intra-workout electrolyte drink without altering the consistency or flavour profile.

Is Optimum Nutrition Micronised Creatine Powder safe for competitive, drug-tested athletes?

Yes. Optimum Nutrition is a globally recognized benchmark brand for purity and strict quality control. This pure monohydrate powder is Informed-Choice certified, meaning samples from every production batch undergo regular, independent laboratory screening for banned substances to ensure total label accuracy and peace of mind for competitive Kiwi sports players.

What is the best liquid to mix creatine powder with?

While it mixes easily with standard cold water, consuming your 5g serving alongside a carbohydrate-based beverage—such as fruit juice or a recovery formula—can be highly beneficial. The presence of natural carbohydrates helps stimulate a mild, everyday insulin surge, which acts as a transport driver to guide the creatine particles directly into muscle cells more efficiently.

ON generally have good products. Difficult to comment on creatine monohydrate as there is no taste. But mixes well and appears to work as well as other monohydrates I have used. I trust the brand so tend to stick with them for most products.
