Incorrect Dosage Information—In the Medical News & Perspectives Health Agencies Update column
published in the June 25, 1997, issue of THE JOURNAL (1997;277:1924), incorrect
dosage information was introduced in editorial revision. In the first sentence
of the third paragraph under the subheading "Advised Folate Intake Falls Short?"
the correct dosages for the National Academy of Sciences' recommended daily
allowance for folate should be 400 μg per day for pregnant women; 180 μg
per day for other women; and 200 μg per day for men.
