Vitamin E EAR and RDA Summary, Ages 1 through 18 Years
EAR for Children
1–3 years
5 mg (11.6 µmol)/day of α-tocopherol
4–8 years
6 mg (14.0 µmol)/day of α-tocopherol
EAR for Boys
9–13 years
9 mg (20.9 µmol)/day of α-tocopherol
14–18 years
12 mg (27.9 µmol)/day of α-tocopherol
EAR for Girls
9–13 years
9 mg (20.9 µmol)/day of α-tocopherol
14–18 years
12 mg (27.9 µmol)/day of α-tocopherol
The RDA for vitamin E is set by assuming a coefficient of variation (CV) of 10 percent (see Chapter 1) because information is not available on the standard deviation of the requirement for vitamin E; the RDA is defined as equal to the EAR plus twice the assumed CV to cover the needs of 97 to 98 percent of the individuals in the group (therefore, for vitamin E the RDA is 120 percent of the EAR). The calculated RDA in milligrams is rounded.
RDA for Children
1–3 years
6 mg (13.9 µmol)/day of α-tocopherol
4–8 years
7 mg (16.3 µmol)/day of α-tocopherol
RDA for Boys
9–13 years
11 mg (25.6 µmol)/day of α-tocopherol
14–18 years
15 mg (34.9 µmol)/day of α-tocopherol
RDA for Girls
9–13 years
11mg (25.6 µmol)/day of α-tocopherol
14–18 years
15 mg (34.9 µmol)/day of α-tocopherol
Adults Ages 19 through 50 Years
Evidence Considered in Estimating the Average Requirement
As stated earlier, although it is known that humans require vitamin E (Cavalier et al., 1998; Hassan et al., 1966; Oski and Barness, 1967; Sokol et al., 1984), overt vitamin E deficiency (characterized by sensory neuropathy, increased erythrocyte fragility, and increased ethane and pentane production) is rare in the United States and
