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 Data points are from unpublished data on percentiles of B vitamin intake from food and supplements, J.D.
