Read serving counts
This reads the label's arithmetic. A labelled serving is not a personal recommendation or safe dose.
Labels
Start with the labelled serving, then check how many tablets, capsules or measures it contains.
In practice
A bottle with sixty units and two units per serving contains thirty labelled servings. That describes the container, not how much a person should take.
Compare cost and quantity on the same label basis while keeping suitability and safety separate.
Label maths
Compare serving cost
Cost does not establish ingredient quality, effectiveness, safety or suitability.
Compare label amounts
Compare the same ingredient form, unit and serving basis. Do not convert this result into a dose.
