1. What is Dietary Calcium Intake?

Dietary calcium intake refers to the total amount of calcium consumed through food and beverages. Calcium is an essential mineral for bone health, muscle function, nerve transmission, and blood clotting.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( \text{Servings} \) — Number of servings consumed
• \( \text{Calcium per Serving (mg)} \) — Calcium content in milligrams per serving
• \( \sum \) — Summation of all calcium-containing items

Explanation: The calculator multiplies the number of servings by the calcium content per serving for each food item, then sums these values to get total calcium intake.

3. Importance of Calcium Intake

Details: Adequate calcium intake is crucial for maintaining bone density, preventing osteoporosis, supporting proper muscle and nerve function, and ensuring normal blood clotting. The recommended daily intake varies by age and gender.

4. Using the Calculator

Tips: Enter the number of servings and calcium content per serving for up to three food items. At least one item is required. Values must be positive numbers.

5. Frequently Asked Questions (FAQ)
