Molybdenum EAR and RDA Summary, Ages 19 Years and Older
EAR for Men
19–50 years
34 μg/day of molybdenum
51–70 years
34 μg/day of molybdenum
> 70 years
34 μg/day of molybdenum
EAR for Women
19–50 years
34 μg/day of molybdenum
51–70 years
34 μg/day of molybdenum
> 70 years
34 μg/day of molybdenum
The number of molybdenum levels in the adult depletion/repletion study was very limited, and the number of subjects was low. Thus, a CV of 15 percent is used; 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 was rounded up.
RDA for Men
19–50 years
45 μg/day of molybdenum
51–70 years
45 μg/day of molybdenum
> 70 years
45 μg/day of molybdenum
RDA for Women
19–50 years
45 μg/day of molybdenum
51–70 years
45 μg/day of molybdenum
> 70 years
45 μg/day of molybdenum
Pregnancy
Evidence Considered in Estimating the Average Requirement
No direct data are available for determining the additional daily requirement for molybdenum during pregnancy. The additional molybdenum requirement during pregnancy is determined by extrapolating up from adolescent and adult women as described in Chapter 2. Carmichael and coworkers (1997) reported that the median weight gain of 7,002 women who had good pregnancy outcomes was 16 kg. No consistent relationship between maternal age
