01
Formula transparency
We examine whether the label identifies each ingredient, its dosage, serving size, and the use of proprietary blends.
Editorial standards
How we research and evaluate supplements
Our reviews examine evidence, formulation transparency, safety, price, and seller practices. We do not treat marketing statements or customer testimonials as clinical proof.
02
Ingredient evidence
We review credible research relevant to the ingredients while distinguishing laboratory findings from human clinical evidence.
03
Complete-product evidence
Evidence supporting an individual ingredient is not treated as proof that the complete supplement produces the same outcome.
04
Safety considerations
We identify known cautions, possible interactions, unsuitable user groups, and situations that require professional medical advice.
05
Pricing and value
We calculate the cost per serving, assess recurring-purchase requirements, and examine shipping, bundles, and subscription terms.
06
Seller transparency
We review contact information, purchasing conditions, refund terms, billing disclosures, and the clarity of the sales process.
Evidence ratings
How we describe the strength of evidence
These labels communicate the quality and relevance of the available evidence. They are not medical diagnoses or guarantees that a product will produce a particular result.
Strong
Supported by relevant human evidence with reasonably consistent findings.
Moderate
Some relevant human evidence exists, but important limitations or uncertainty remain.
Limited
Evidence is preliminary, indirect, inconsistent, or based mainly on small studies.
Unverified
We could not locate adequate evidence supporting the specific claim or complete formula.
