1. What is Daily Value Percentage?

Daily Value Percentage (%DV) indicates how much a nutrient in a serving of food contributes to a daily diet. It helps consumers understand the nutrient content of foods in the context of a total daily diet.

2. How Does the Calculator Work?

The calculator uses the Daily Value Percentage formula:

Where:

• \( amount \) — Actual amount of nutrient (mg)
• \( DV \) — Daily Value reference amount (mg)

Explanation: The formula calculates the percentage of the daily recommended value that a specific amount of nutrient provides.

3. Importance of %DV Calculation

Details: %DV helps consumers make informed food choices, compare nutritional content between products, and maintain a balanced diet according to recommended daily nutrient intake levels.

4. Using the Calculator

Tips: Enter the nutrient amount in mg and the daily value reference amount in mg. Both values must be positive numbers, with DV greater than zero.

5. Frequently Asked Questions (FAQ)

A: %DV doesn't account for individual dietary needs and is based on general population recommendations. It may not be appropriate for people with specific medical conditions.
