a The EAR and AI for vitamin A are expressed as retinol activity equivalents (RAEs) per day. 1 RAE = 1 mcg retinol, 12 mcg -carotene, 24 mcg -carotene, or 24 mcg -cryptoxanthin.
b The EAR and AI for vitamin E are expressed as mg -tocopherol (AT) per day. The EAR and AI for vitamin E include RRR--tocopherol, the only form of -tocopherol that occurs naturally in foods, and the 2R-stereoisomeric forms of -tocopherol that occur in fortified foods and dietary supplements. The UL for vitamin E applies to any form of -tocopherol used in dietary supplements or added to foods as a fortificant or antioxidant. Note that the CSFII data used elsewhere in this report were originally calculated as mg -tocopherol equivalents (ATE) per day, an older unit of measure for vitamin E.
