Creatine monohydrate is one of the most studied ingredients used for high-intensity exercise. For most shoppers, the best starting point is a simple product with a clearly stated creatine monohydrate dose, transparent ingredients, and a price that makes sense per serving.
Our top pick criteria
We do not rank products by commission rate. Key Score™ weighs evidence, formula and dose, testing and transparency, and value. Because creatine monohydrate is the ingredient with the strongest research base, a plain monohydrate formula is generally easier to evaluate than a proprietary blend.
What to look for
- Creatine monohydrate clearly named on the Supplement Facts panel.
- A stated dose with no hidden proprietary blend.
- Few unnecessary active ingredients.
- Batch testing or credible quality information when available.
- Price compared by full serving, not only container price.
What to skip
- Products that promise to cure a condition or transform results without training.
- Blends that do not disclose the amount of creatine.
- Paying a large premium for a different form without a clear reason.
Current products to compare
- Thorne Creatine — premium positioning and a simple formula.
- Optimum Nutrition Micronized Creatine — a mainstream monohydrate option; full review coming soon.
- Sports Research Creatine Monohydrate — a single-ingredient option; full review coming soon.

How the scores were set
Ingredient evidence matters most in this category: both scored products use creatine monohydrate at a stated 5 g serving. Thorne earns a higher transparency score because its Creatine is listed by NSF Certified for Sport®. Optimum Nutrition earns a stronger value score based on its current direct-store price per serving. Scores are editorial judgments, not medical advice or a guarantee of product suitability. We will revisit them when product labels, testing status, or pricing materially change.

Key Score™ framework
For creatine, we place the greatest weight on an evidence-aligned ingredient, transparent dosing, quality information, and sensible price. We update product pages when labels, certification information, or pricing meaningfully change.
Bottom line
A transparent creatine monohydrate product is the sensible comparison point for most adults considering creatine for repeated high-intensity training. Speak with a clinician before using a supplement if you have a medical condition, take medications, are pregnant, or have questions about your individual situation.
