If a vitamin supplement is needed to improve health, here are some tips when shopping for supplements. Look for the USP (U.S. Pharmacopeial Convention) Verified Mark. This mark means that the supplement:
- Contains the ingredients listed on the label, in the declared strength and amounts;
- Does not contain harmful levels of specified contaminants; and
- Is made according to FDA and USP Good Manufacturing Practices, using sanitary and well-controlled processes.
USP standards are enforced by the U.S. Food and Drug Administration. But, the use of the USP label is voluntary. Using the label signifies a commitment to good quality supplements. Learn more at www.usp.org/usp-verification-services
