Dietary Reference Intakes (DRI) represent a new approach to assessing and planning diets for healthy individuals and groups, and have replaced the former Recommended Dietary Allowances (RDAs). The DRIs are a more complete set of values which include:

• Recommended Dietary Allowances (RDA)
• Adequate Intakes (AI)
• Tolerable Upper Intake Levels (UL)
• Estimated Average Requirements (EAR)

See the Interactive DRI Glossary for detailed nutrient descriptions and terminology.

Below is a list of nutrients sorted by value type.

RDA Nutrients for age one and older:
RDA values are derived from EAR values; thus, EAR values are not listed separately.

Carbohydrate
Copper
Folate
Iodine
Iron
Magnesium
Molybdenum
Niacin
Phosphorus
Protein (plus infants 7-12 months)
Riboflavin
Selenium
Thiamin
Vitamin A
Vitamin B6
Vitamin B12
Vitamin C
Vitamin E
Zinc

AI Nutrients include:
All of the above for infants up to 12 months, plus protein (infants 0-6 months).

Protein (infants 0-6 months)

For age one and older:

Alpha-linolenic acid
Biotin
Calcium
Chloride
Choline
Chromium
Fat (infants 0-12 months)
Fluoride
Linoleic acid
Manganese
Pantothenic Acid
Potassium
Sodium
Total fiber
Vitamin D
Vitamin K
Water

UL Nutrients:
UL data is unavailable for infants 0-12 months, except for those nutrients followed by an asterisk.

Boron
Calcium
Chloride
Choline
Copper
Folate
Fluoride*
Iodine
Iron*
Magnesium
Manganese
Molybdenum
Niacin
Nickel
Phosphorus
Selenium*
Sodium
Vitamin A*
Vitamin B6
Vitamin C
Vitamin D*
Vitamin E
Vanadium
Zinc*

Some nutrients may not have a UL due to lack of data of adverse effects in a particular age group and concern with regard to lack of ability to handle excess amounts. View the DRI Tables to review the RDA, AI, and UL values for each nutrient.
