How to read a Supplement Facts label
The label helps you identify what the manufacturer says is in a serving. It does not, by itself, establish that the product is effective.
Serving size
Compare research doses and product amounts on the same serving basis.
Ingredient amount
An ingredient name without a meaningful amount makes evidence comparison difficult.
Proprietary blends
A blend may list a total amount while withholding individual quantities. That limits dose-level evaluation.
Other ingredients and warnings
Check excipients, allergens and directions as well as headline ingredients.
