How to Use the Calcium Calculator
- Enter servings for each food item in the provided fields. Use numbers (e.g., 1, 0.5, 1.25). Each field shows the calcium content per serving (e.g., 1 cup milk = 300 mg).
- Provide your age (0–120 years) and select your gender from the dropdown.
- Click the "Calculate" button.
- View your results:
- Total Calcium Intake – sum of all food contributions in mg.
- Recommended Daily Allowance (RDA) – based on age and gender (1000 mg for most adults, 1200 mg for women over 50 or men over 70).
- Percentage of RDA – how much of your daily need you’ve met.
Tips:
- All inputs must be non-negative numbers. Invalid entries will show a red error.
- Use fractional servings (e.g., 0.25 for a quarter cup) for accuracy.
- No unit conversion needed – all values are in standard servings (cups, ounces, etc.).
