FDA Daily Values: RDI vs DRV
RDI for 29 micronutrients and DRV for 8 macronutrients with % Daily Value.
FDA Daily Values consist of two distinct standards — RDI for vitamins and minerals and DRV for macronutrients — that together produce the % Daily Value figures printed on every US Nutrition Facts label. Both are defined in 21 CFR § 101.9 and anchored to a 2,000-calorie reference diet for adults and children aged 4 and older.
What are FDA Daily Values and why do they exist?
This guide focuses specifically on United States of America implementation of recommended daily intakes through FDA regulations. For a broader understanding of the universal concept of recommended intakes, see Recommended Daily Intakes.
How does the US implement Daily Values on nutrition labels?
The "% Daily Value" on US nutrition labels represents a percentage based on two distinct FDA standards:
- RDI (Reference Daily Intake): For vitamins and minerals (29 micronutrients, 4 mandatory)
- DRV (Daily Reference Value): For macronutrients and food components (8 nutrients, all mandatory)
Together, these standards form what consumers know as "Daily Values" (DV).
Understanding the distinction between RDI and DRV matters for:
- Regulatory Compliance: Accurate nutrition labeling requirements under FDA regulations
- Consumer Education: Helping people interpret US nutrition labels correctly
- Product Development: Reformulating products to meet nutritional goals for the US market
How do RDI and DRV work together to produce % Daily Value?
What is % Daily Value?
The % Daily Value (%DV) indicates the contribution of a nutrient in a serving of food to a total daily diet. The FDA bases these calculations on a 2,000 calorie reference diet for adults and children 4 years and older.
%DV Interpretation Guidelines:
- 5% DV or less = Low in that nutrient
- 20% DV or more = High in that nutrient
Nutrients to limit (saturated fat, sodium, added sugars) should have lower %DV values. Nutrients to increase (fiber, calcium, vitamin D) should have higher %DV values.
What is RDI and which vitamins and minerals does it cover?
RDI represents the daily intake level of essential vitamins and minerals. These are micronutrients the body requires in small amounts but cannot produce independently.
- Applies to: 29 micronutrients (4 mandatory, 25 voluntary)
- Regulatory source: 21 CFR § 101.9(c)(8)(iv) - Table 1

Voluntary nutrients become mandatory when added to a product or a nutrient content claim is made.
What is DRV and which macronutrients does it govern?
DRV represents the daily intake level of macronutrients and food components that provide energy or affect chronic disease risk.
- Applies to: 8 macronutrients and food components
- Regulatory source: 21 CFR § 101.9(c)(9) - Table 2
- Based on: 2,000 calorie diet
Complete DRV Table
| Nutrient | DRV Value | Unit | Mandatory | Notes |
|---|---|---|---|---|
| Total Fat | 78 | g | Y | Based on 35% of calories |
| Saturated Fat | 20 | g | Y | Less than 10% of calories |
| Cholesterol | 300 | mg | Y | Upper limit |
| Total Carbohydrate | 275 | g | Y | Based on 55% of calories |
| Dietary Fiber | 28 | g | Y | 14g per 1,000 calories |
| Added Sugars | 50 | g | Y | Less than 10% of calories |
| Protein | 50 | g | Y | Based on 10% of calories |
| Sodium | 2,300 | mg | Y | Upper limit (also in RDI) |
Mandatory (Y): Must always appear on Nutrition Facts label.
Which population groups does the FDA define for Daily Value labeling?
The FDA defines 4 demographic groups for nutrition labeling purposes under 21 CFR § 101.9:
| Demographic Group | Age Range | Special Notes |
|---|---|---|
| Adults & Children | ≥ 4 years | Default reference group (2,000 cal diet) |
| Infants | 0-12 months | Separate DV values apply |
| Children | 1-3 years | Separate DV values apply |
| Pregnant & Lactating | Varies | Separate DV values apply |
Most nutrition labels use the Adults & Children ≥4 years values as these represent the general population reference.
What FDA regulations govern Daily Value compliance for food manufacturers?
Where in the CFR are Daily Value tables codified?
The complete legal framework for Daily Values appears in the Code of Federal Regulations:
- Primary Regulation: 21 CFR § 101.9 - Nutrition labeling of food
- RDI (Table 1): 21 CFR § 101.9(c)(8)(iv)
- DRV (Table 2): 21 CFR § 101.9(c)(9)
When do voluntary RDI nutrients become mandatory on the label?
Nutrients marked as voluntary (N) in the tables above become mandatory when:
- The nutrient is added to the product (fortification)
- A nutrient content claim is made (e.g., "High in Vitamin C")
- The product is a dietary supplement
Example: A cereal fortified with Vitamin C that claims "Excellent Source of Vitamin C" must declare Vitamin C on the label with its %DV.
