Calculadora de Valor Diário de Vitaminas — Formula

## How to Calculate Vitamin Daily Value

### Formula

**% DV = (Amount in Serving / Daily Value) x 100**

### Labeling Rules

- 5% DV or less is considered LOW
- 20% DV or more is considered HIGH

### Key Daily Values (Adults)

- Vitamin C: 90 mg
- Vitamin D: 20 mcg
- Vitamin A: 900 mcg
- Vitamin B12: 2.4 mcg

Exemplo Resolvido

An orange provides 30 mg of Vitamin C.

  1. % DV: (30 / 90) x 100 = 33.3%.
  2. Remaining: 90 - 30 = 60 mg to meet daily value.
  3. One orange provides about a third of daily Vitamin C.
