NootroScore™
Our comprehensive rating system that helps you find the best supplements
What is NootroScore™?
NootroScore™ is our proprietary rating system designed to objectively evaluate and compare supplements across multiple factors. Our team of experts analyzes each product through a rigorous methodology to provide you with a single, easy-to-understand score that represents the overall quality and value of a supplement.
Example of a high-quality supplement with a score of 9.2
How We Calculate the NootroScore™
Efficacy (35%)
Based on scientific evidence, clinical trials, and peer-reviewed research that supports the effectiveness of the active ingredients.
Safety (22%)
Evaluation of potential side effects, contraindications, and overall safety profile of the supplement and its ingredients.
Transparency (15%)
Assessment of clear ingredient disclosure, honest marketing claims, public availability of research, and company accountability practices.
Quality (13%)
Assessment of manufacturing standards, quality control processes, third-party testing, and certification of the product.
Value (8%)
Analysis of price per serving, dose effectiveness, and overall value compared to similar products in the market.
User Experience (7%)
Consideration of user reviews, reported experiences, and customer satisfaction across multiple platforms.
Understanding the Score Range
Exceptional supplements with outstanding efficacy, safety, and quality. These are the gold standard in their category.
High-quality supplements with solid scientific backing and good overall value. Recommended options for most users.
Decent supplements that may work for some users but have limitations in efficacy, quality, or value.
Supplements with limited evidence of effectiveness, potential safety concerns, or poor value. Generally not recommended.
Our Methodology
At NootroWorld, we've developed a comprehensive evaluation process to ensure that our NootroScore™ ratings are accurate, fair, and scientifically sound. Here's how we approach the evaluation of supplements:
Research Collection
Our team of nutrition scientists and medical professionals gather all available scientific literature, clinical trials, and research studies related to the supplement's ingredients and formulation.
Data Analysis
We evaluate the quality, quantity, and consistency of scientific evidence supporting each ingredient's efficacy and safety, with emphasis on peer-reviewed, placebo-controlled human studies.
Quality Assessment
We review manufacturing protocols, certifications, testing practices, and the presence of quality assurance measures like third-party testing and Good Manufacturing Practices (GMP) certification.
User Experience Evaluation
We collect and analyze user reviews, feedback, and experiences from verified purchasers across multiple platforms to assess real-world effectiveness and satisfaction.
Transparency Verification
We assess the clarity and completeness of ingredient disclosure, the honesty of marketing claims, and the company's willingness to share research and information about their products.
Value Analysis
We calculate the cost per serving and evaluate the overall value proposition, comparing the product against others in its category to determine if the price point is justified.
Scoring and Review
Our evaluation committee assigns scores for each category based on the collected data, which are then weighted according to our formula to produce the final NootroScore™.
All NootroScores™ are regularly reviewed and updated as new research, formulations, or feedback becomes available. We are committed to providing the most current and accurate information possible.
Version History
The NootroScore™ system is continually evolving as new research emerges and our understanding of supplement efficacy improves. Here's how our rating system has evolved over time:
Current Version: Enhanced Transparency Factor
March 2025- Added Transparency (15%) as a major new scoring factor to account for ingredient disclosure, honest marketing, and company accountability
- Rebalanced Weights: Adjusted existing categories to accommodate the new transparency factor while maintaining a 100% total
- Efficacy: 40% → 35%
- Safety: 25% → 22%
- Quality: 15% → 13%
- Value: 10% → 8%
- User Experience: 10% → 7%
Refined Quality Assessment
November 2024- Enhanced Quality Evaluation: Added more stringent criteria for manufacturing standards assessment, including third-party certifications
- User Experience Refinement: Improved methodology for collecting and analyzing user reviews across multiple platforms
- Value Calculation Update: Developed more precise formula for calculating cost per effective dose
Five-Factor Model
March 2023- Expanded to Five Factors: Added Value (10%) and User Experience (10%) as distinct scoring categories
- Rebalanced Weights: Efficacy (40%), Safety (25%), Quality (15%), Value (10%), User Experience (10%)
- Improved Scientific Analysis: Enhanced criteria for evaluating clinical studies and research quality
Initial Release: Three-Factor Model
July 2022- Original Three Factors: Efficacy (50%), Safety (30%), Quality (20%)
- Basic Score Range: Established the 0-10 scoring system with simple tier classifications
- Foundation Work: Created initial framework for evaluating supplements based on scientific evidence
Future Development
We're constantly working to improve the NootroScore™ system. Future enhancements being considered include:
- Individual bioavailability assessment for specific ingredients
- Population-specific scoring adjustments (for athletes, seniors, etc.)
- Environmental sustainability and ethical sourcing factors
- Integration of emerging pharmacogenomic research
