What Is Creatine Monohydrate?

Creatine monohydrate is one of the most studied sports-nutrition ingredients, with an extensive human and meta-analytic research base spanning muscle strength, power, lean-mass preservation, exercise recovery, and — increasingly — cognition and brain energy metabolism. Creatine supports the resynthesis of ATP, the cell’s primary energy currency. The general- ingredient research supports creatine monohydrate supplementation broadly; that evidence should not be attributed to any specific branded creatine (such as Pürest) unless the actual study used that branded material. Wellnex uses a branded creatine monohydrate while presenting the supporting research as ingredient-level evidence, attributing branded-specific claims only to studies that actually used the branded product.

Creatine Monohydrate vs Other Forms

Creatine monohydrate remains the most research-backed form: nearly every major meta-analysis, consensus position, and systematic review is conducted on monohydrate. Newer forms (hydrochloride, micronized, buffered, ethyl ester) are marketed on convenience or solubility, but the head-to-head and meta-analytic evidence base overwhelmingly favors monohydrate on both efficacy and cost. For any formula where the objective is a defensible creatine claim, monohydrate is the standard.

Research Highlights

Meta-Analyses

Strength & Power

Multiple meta-analyses support creatine for strength, power, and lean-mass gains with resistance training.

Human Research

Healthy Aging

Creatine is studied for preserving muscle and functional capacity with aging.

Emerging Human Research

Cognition

Studies examine creatine’s role in brain energy metabolism and cognitive outcomes.

Human Research

Women & Creatine

Recent work examines creatine effects in women across performance and health contexts.

Evidence Distinction

Research labeled “Branded Ingredient Study” used the named branded material. Research labeled “Ingredient-Level Research” studied the nutrient or ingredient class generally and is informative without implying the same exact material was used. We do not imply a study used a branded ingredient unless the publication identifies it.

Systematic ReviewIngredient-Level ResearchStrong

International Society of Sports Nutrition position stand: safety and efficacy of creatine supplementation in exercise, sport, and medicine

Kreider RB, et al.

Journal of the International Society of Sports Nutrition, 2017

The ISSN position stand affirms creatine monohydrate is the most effective and best-researched form for strength, lean mass, and high-intensity performance.

Population:Athletes and general populations

Participants:—

Duration:Acute to long-term

Dose:3–5 g/day (typical)

Primary Area:Performance, body composition, safety

Key Finding

The ISSN concludes creatine monohydrate is the most effective and best-researched ergogenic supplement for improving high-intensity exercise capacity and lean mass, with a strong safety profile.

The effect of creatine supplementation on resistance training-based changes to body composition: A systematic review and meta-analysis

Desai I, et al.

Journal of Strength and Conditioning Research, 2024

A 2024 meta-analysis found creatine plus resistance training added ~1.1 kg lean mass and reduced fat versus training alone in adults under 50.

Population:Adults <50 y

Participants:12 RCTs

Duration:Resistance-training programs

Dose:~7 g/day (or 0.3 g/kg) vs placebo

Primary Area:Lean body mass, body-fat %, fat mass

Key Finding

Creatine added to resistance training increased lean body mass by 1.14 kg and reduced body-fat percentage and fat mass versus resistance training alone.

Frequently Asked Questions

What does creatine do?

Creatine supports ATP resynthesis, supporting repeated high-intensity muscle work; research also explores roles in cognition and healthy aging.

Is creatine monohydrate the best form?

It has the strongest evidence base; nearly all major meta-analyses use creatine monohydrate.

How much creatine should I take?

Common researched doses are 3–5 g daily; loading protocols (e.g., 20 g for 5–7 days) are optional.

Does creatine research apply to Pürest specifically?

Only studies that actually used Pürest support brand-specific claims. General creatine monohydrate research supports the ingredient class, not the specific brand.

Is creatine studied in women?

Yes — recent research examines creatine responses and applications in women.
