How to Read a Supplement Facts Label

A label will not tell you whether a supplement works for you, but it gives you the minimum data needed to ask better questions.

Serving size

Ingredient amounts are tied to the stated serving. Do not compare bottle counts without comparing servings.

Ingredient amount

Exact amounts help you compare a product with research. If multiple ingredients are grouped into a proprietary blend, dose-level comparison may be limited.

Other ingredients

Capsule materials, excipients and other non-active ingredients may matter for allergies, dietary preferences or tolerability.
