The Dietary Supplements Sector of United States Pharmacopeia (USP) has designed a fact sheet to guide and inform pharmacists about quality considerations for dietary supplements. The guidelines recommend helping consumers understand how quality is defined and why it matters, as well as advising them to look for certain trusted third-party quality verification indicators, such as USP Verified, when selecting a product. The fact sheet also includes signs consumers can look for to help determine if a supplement might be tainted with illegal or harmful ingredients. The fact sheet can be downloaded from the USP website.
