Dietary Reference Intakes for Vitamin A, Vitamin K, Arsenic, Boron, Chromium, Copper, Iodine, Iron, Manganese, Molybdenum, Nickel, Silicon, Vanadium, and Zinc
and weight gain was observed in six studies of U.S. women (IOM, 1990). Therefore, 16 kg is added to the reference weight for adolescent girls and adult women for extrapolation.
Molybdenum EAR and RDA Summary, Pregnancy
EAR for Pregnancy
14–18 years
40 μg/day of molybdenum
19–30 years
40 μg/day of molybdenum
31–50 years
40 μg/day of molybdenum
The RDA for molybdenum is set by using a CV of 15 percent (see “Adults Ages 19 Years and Older”). The RDA is defined as the EAR plus twice the CV to cover the needs of 97 to 98 percent of the individuals in the group (therefore, for molybdenum the RDA is set at 130 percent of the EAR). The calculated RDA is rounded to the nearest 10 μg.
RDA for Pregnancy
14–18 years

Lactation
Evidence Considered in Estimating the Average Requirement
The EAR for lactation is estimated as the sum of the molybdenum intake necessary to replace the molybdenum secreted daily in human milk and the EAR for adolescent girls and women. Based on a daily excretion of 2 μg/day, the EAR for molybdenum is set at 35 and 36 μg/day for lactating adolescents and adults, respectively.
