Creatine monohydrate is the gold standard in sports nutrition supplements, with decades of research supporting its efficacy, safety, and bioavailability. This product provides 5 grams per serving of micronized creatine monohydrate, a form shown to enhance intramuscular phosphocreatine stores, enabling faster ATP regeneration during short-duration, high-intensity activities such as weightlifting and sprinting [1][2]. The micronization process improves solubility and mixability, though it does not alter the fundamental bioavailability of creatine itself.

The dose of 5 g/day aligns precisely with the recommended maintenance phase following a loading protocol or as a standalone daily intake to achieve muscle saturation over 3–4 weeks [1]. While a loading phase (0.3 g/kg/day for 5–7 days) can accelerate muscle creatine accumulation, consistent daily dosing at 5 g is effective and well-tolerated long-term. This product contains no additional ingredients, ensuring purity and minimizing potential for adverse reactions or interactions.

Quick Summary

Transparency100

Full transparency: exact amount of creatine monohydrate (5 g) is clearly listed with no proprietary blends or hidden ingredients.

Efficacy90

High efficacy due to 5 g of creatine monohydrate per serving, which is at the clinical midpoint (3–5 g) and proven to enhance performance, strength, and lean mass with regular use.

Bioavailability95

Creatine monohydrate has excellent bioavailability (~95%), and the micronized form enhances dispersion in liquid, improving user experience without altering absorption kinetics.

Safety95

Excellent safety profile in healthy individuals; no evidence of organ toxicity with long-term use. High-quality manufacturing standards from Optimum Nutrition further support safety.

Suggested: 1 serving/day to reach clinical midpoint

Why Take This Product

You should consider taking Micronized Creatine Powder, Unflavored by Optimum Nutrition if you're looking to improve performance in high-intensity, short-duration exercises such as resistance training, sprinting, or interval-based sports. The 5 g dose of creatine monohydrate per serving is clinically validated to increase muscle phosphocreatine levels, which enhances energy production during anaerobic activity, leading to improved strength, power output, and training capacity. It is especially beneficial when taken consistently alongside a structured exercise program.

Key Benefits

  • Enhanced Exercise Performance: Creatine monohydrate supplementation increases intramuscular phosphocreatine stores, supporting rapid ATP regeneration during high-intensity exercise, leading to improved performance in activities like weightlifting and sprinting [1][2].
  • Increased Muscle Strength and Power: Clinical studies show that creatine combined with resistance training significantly improves muscle strength and power output in both men and women [5][3].
  • Greater Lean Mass Gains: Long-term creatine use with resistance training leads to greater increases in fat-free mass compared to placebo, likely due to enhanced training capacity and cell hydration [3].
  • Improved Recovery and Injury Prevention: Emerging evidence suggests creatine may reduce muscle damage and inflammation post-exercise, supporting faster recovery and potentially lowering injury risk [2].
  • Neuroprotective and Cognitive Benefits: Creatine plays a role in brain energy metabolism, with some studies indicating benefits in cognitive performance under stress, sleep deprivation, or aging [2].

Who Should Take This

This product is ideal for athletes, fitness enthusiasts, and individuals engaged in resistance or high-intensity training who want to improve strength, power, and muscle mass. It is also suitable for older adults seeking to combat age-related muscle loss (sarcopenia), vegetarians (who typically have lower dietary creatine intake), and females aiming to enhance training adaptations. Healthy individuals with normal kidney function can use it safely for both short- and long-term supplementation.

Potential Side Effects

The most common side effect is transient water retention in muscles, particularly during initial use, which may lead to slight weight gain. Gastrointestinal discomfort (e.g., bloating or cramping) may occur with large doses but is minimized with split dosing or consistent 5 g/day intake. There is no evidence of kidney damage in healthy individuals, even with long-term use [6][4]; however, those with pre-existing kidney conditions should avoid creatine or consult a healthcare provider. Staying well-hydrated is recommended.

Ingredient Breakdown

Each serving contains a single active ingredient: creatine monohydrate. This compound is naturally synthesized in the body and obtained through diet (primarily meat and fish), but supplementation ensures maximal intramuscular saturation for performance and health benefits.

Primary Ingredients

Creatine Monohydrate

Enhances high-intensity exercise performance, increases muscle strength and lean mass

5 g
per capsuleGoal: 3-5 g

Micronized form improves solubility and mixability. Dose of 5 g/day is at the upper end of the clinical range and sufficient for maintenance or standalone use without loading.

Creatine monohydrate is the most effective and well-studied form of creatine, proven to increase intramuscular phosphocreatine and support ATP regeneration during anaerobic activity. It is safe, well-tolerated, and effective in both males and females [1][3].

Practical Recommendations

  • Daily Dosing Without Loading: Take one 5 g scoop daily, with or without food. Muscle saturation occurs within 3–4 weeks, making this a simple and effective approach.
  • Accelerated Loading Phase (Optional): For faster saturation, take 20 g per day (split into 4 doses) for 5–7 days, followed by 5 g/day for maintenance [1].
  • Timing And Co-Ingestion: While not required, taking creatine with carbohydrates or protein may enhance uptake due to insulin-mediated transport. Post-workout timing may offer slight advantages in muscle accretion.

Is it Safe?

Creatine monohydrate is one of the most studied supplements in sports science, with an excellent safety profile across diverse populations. Long-term studies show no adverse effects on renal, hepatic, or cardiac function in healthy individuals [4][2].

Safety & Considerations

  • Renal Impairment: Avoid in individuals with severe renal impairment; monitor kidney function in those with pre-existing kidney disease.
  • Hydration: Ensure adequate fluid intake to minimize risk of gastrointestinal discomfort or cramping.

The Science

The efficacy of this product is driven entirely by its 5 g dose of creatine monohydrate—the most bioavailable and well-researched form. This dose meets clinical standards for maintaining elevated muscle creatine levels and enhancing physical performance.
