Erratum

        In “Is Nutrient Content and Other Label Information for Prescription Prenatal Supplements Different from Nonprescription Products?” from the September 2017 issue of the Journal (117(9):1429-1436), an error appears in Table 1, which affects the text in the results and conclusions sections on the proportion of products that exceed the UL levels for folate. The Tolerable Upper Intake Levels (ULs) for folate established by the Food and Nutrition Board (FNB) of the National Academies of Sciences, Engineering, and Medicine, applies to the synthetic form of folate obtained from supplements, fortified foods, or a combination of the two, ie, the amounts are in micrograms folic acid and not dietary folate equivalents (DFE). Thus, the UL range for pregnant and lactating women is 800-1,000 μg folic acid and not 480-600 μg folic acid as reported in the paper. Using the corrected values, the percentage of prescription prenatal supplements that were at or exceed the 1,000 μg UL amount is 99% and the percentage of nonprescription prenatal supplements that were at or exceed the 1,000 μg UL amount is 16%. The authors regret this error.
