NOTE
: An Estimated Average Requirement (EAR) is
the average daily nutrient intake level es
timated to meet the requirements of half
of the healthy individuals in a group. EARs
have not been established for vitamin K,
pantothenic acid, biotin, choline, chromium
, fluoride, manganese, or other nutrients
not yet evaluated via the DRI process.
a
As retinol activity equivalents (RAEs). 1 RAE = 1 μg retinol, 12 μg β-carotene, 24 μg α-carotene, or 24 μg β-cryptoxanthin. The RAE for dietary provitamin A carote
noids is two-fold greater than retinol equivalents
(RE), whereas the RAE for preformed vitamin A is the same as RE. b
As α-tocopherol. α-Tocopherol includes
RRR-α-tocopherol, the only form of α-tocopherol that occurs naturally in foods, and the
2R
-stereoisomeric forms of α-tocopherol (RRR-, RSR-, RRS
-, and
RSS-α-tocopherol)
that occur in fortified foods and su
pplements. It does not include the
2S
-stereoisomeric forms of α-tocopherol (
SRR-, SSR-, SRS
-, and
SSS-α-tocopherol), also found in fortified foods and supplements. c
As niacin equivalents (NE). 1 mg
of niacin = 60 mg of tryptophan. d
As dietary folate equivalents (DFE). 1 DFE = 1
µg food folate = 0.6 µg of folic acid from fortified food or as
a supplement consumed with food = 0.5 µg of a supplement taken
on an empty stomach.
