Molybdenum AI Summary, Ages 0 through 12 Months
AI for Infants
0–6 months

Special Considerations
Cow milk contains considerably more molybdenum (50 μg/L) than human milk, as does soymilk (Tsongas et al., 1980). Data on the bioavailability of molybdenum in cow milk and infant formulas are not available.
Children and Adolescents Ages 1 through 18 Years
Evidence Considered in Estimating the Average Requirement
No data are available on which to base an Estimated Average Requirement (EAR) for children or adolescents. EARs for these groups were extrapolated from adult EARs by the method described in Chapter 2. Although there are no studies available to indicate that the molybdenum requirement is associated with energy expenditure, metabolic weight (kg0.75) was used for extrapolating because of the functional role of molybdenum in a select number of enzymes, and because using metabolic weight yields an EAR that is higher than when total body weight is used.
Molybdenum EAR and RDA Summary, Ages 1 through 18 years
EAR for Children
1–3 years

4–8 years
17 μg/day of molybdenum
EAR for Boys
9–13 years
26 μg/day of molybdenum
14–18 years
33 μg/day of molybdenum
EAR for Girls

The Recommended Dietary Allowance (RDA) for molybdenum is set by using a coefficient of variation (CV) of 15 percent (see “Adults Ages 19 Years and Older”).
