This guidance document provides step-by-step instructions to manufacturers of retail food products marketed in the United States on how they may convert the previous units of measure for certain nutrients to the new units in the updated Nutrition Facts label (81 FR 33742 at 33906-33916 and § 101.9 (21 CFR 101.9)). This guidance document also provides conversion factors that can be used for each of these nutrients and example  calculations for converting to the new units of measure for conventional foods and dietary supplements. Lastly, this guidance document provides information that can help manufacturers understand and comply with relevant labeling requirements.

FDA's guidance documents, including this guidance, do not establish legally enforceable responsibilities. Instead, guidances describe our current thinking on a topic and should be viewed only as recommendations, unless specific regulatory or statutory requirements are cited. The use of the word should in our guidance documents means that something is suggested or recommended, but not required.
