Comparing supplement formats

A capsule count and a powder weight tell you different things about a package.

Use the same unit of comparison

Check how the label defines one serving for each format. Two bottles with the same capsule count can contain different numbers of labeled servings. For a powder, check the stated serving weight and any measuring instructions.

Work out the cost per serving

Divide the package price by the labeled number of servings. This helps compare costs even when package sizes differ. Compare ingredients and warnings separately before making a choice. FDA label questions and answers.
