What goes into a score
Every product is meticulously examined by our team by the following criteria.
Manufacturing Standards
Manufacturing standards ensure that a dietary supplement meets brand specifications and adheres to federal safety and quality regulations.
Brand Certifications
3rd party certification verifies that a brand meets a stringent and standardized set of quality requirements based on independent testing and evaluation of its finished products.
Product Certifications
3rd party certification verifies that a brand's products meet a stringent and standardized set of clean, non-toxic requirements based on independent testing and evaluation of its ingredients.
Product Quality Indicators
Product quality indicators highlight areas where a supplement's ingredients surpass standard regulations to ensure high quality and safety, even in the absence of 3rd party certification.
Testing Benchmarks
Testing benchmarks denote when, in addition to federally required tests, a brand performs non compulsory testing using 3rd party, internationally accredited labs, and shares transparent results.
Technical Innovation
Innovation denotes a brand that underscores the scientific validity and efficacy of its products by performing clinical tests or including doctors and scientists on its leadership team.
