FIGURE 13-4 Distribution of reported total vitamin B12 intake for men and women aged 19 years and older, Third National Health and Nutrition Examination Survey, 1988–1994. Reported intakes of vitamin B12 (diet plus supplements) are well above the Estimated Average Requirement (EAR) for young men and women. Data were adjusted for within-person variability. Vitamin B12 intake values were rounded to the nearest 1.0 µg and all values greater than 25 µg were recorded as 25 µg. Data points are from unpublished data on percentiles of B vitamin intake from food and supplements, J.D.Wright, National Center for Health Statistics, Centers for Disease Control and Prevention, 1998.
