Understanding SupplementAI Product Quality (Beta)
SupplementAI's product-quality system draws from over 100,000 research papers and clinical trials to create a single, transparent product quality rating. It reflects how strong the science is behind a product's ingredients and how reliable the brand appears to be.
Higher ratings reflect stronger evidence and better practices, but no rating is absolute. Ratings evolve as our models improve and should never replace professional medical advice.
What Product Quality Means
A higher product quality rating usually means the product comes from a brand with solid testing and transparency, uses well-researched ingredients at effective doses, and avoids unnecessary or risky additives.
A lower rating doesn't necessarily mean the product is unsafe; it may simply indicate weaker evidence or limited transparency.
How Product Quality Is Built
High-importance factors
- Brand Quality Index (BQI): Evaluates third-party testing, ISO-accredited labs, public COAs, certifications, and labeling transparency. Foundational indicators such as lot testing, independent verification, and public batch reports act as credibility multipliers.
Lower-impact adjustments
- Ingredient Evidence: Assesses the strength of human research supporting each ingredient and how effectively it's dosed. Ingredients with limited data default to a conservative baseline rather than inflating the rating. This is a supporting adjustment, not the primary driver of product quality.
- Inactive Ingredient Safety: Small penalties for questionable excipients, fillers, dyes, or unnecessary additives.
- Ingredient Interactions: Minor positive or negative adjustments depending on whether ingredients are known to complement or conflict with one another.
Transparency, Not Absolutes
Our goal is to give you a consistent, research-based measure of supplement quality and evidence strength, not a medical verdict.
Disclaimer: Product quality ratings are dynamic and may change as our models improve. They are not personalized medical advice. A high rating does not guarantee safety or effectiveness, and a low rating does not imply that a product is unsafe. Always consult a qualified healthcare professional before making supplement decisions.
