Iron Consumption Calculator

Iron is an essential mineral that plays a crucial role in many bodily functions, including oxygen transport, energy production, and immune function. This calculator helps you determine your daily iron consumption needs based on your age, gender, and lifestyle factors.

How to Use This Calculator

To calculate your daily iron consumption needs:

Enter your age in years
Select your gender (male or female)
Select your activity level (sedentary, moderately active, or active)
Select whether you're pregnant or breastfeeding (if applicable)
Click the "Calculate" button

The calculator will display your recommended daily iron intake in milligrams (mg).

Iron Requirements by Age and Gender

Iron requirements vary significantly by age and gender. The following table provides general guidelines:

Age Group	Male (mg/day)	Female (mg/day)
Infants (0-6 months)	0.7	0.7
Infants (7-12 months)	7	7
Children (1-3 years)	7	7
Children (4-8 years)	10	10
Children (9-13 years)	10	15
Adolescents (14-18 years)	11	15
Adults (19-50 years)	8	18
Adults (51+ years)	8	8
Pregnant women	27	27
Breastfeeding women	9	9

Note: These are general guidelines. Individual needs may vary based on health status, diet, and other factors.

Calculation Method

The calculator uses the following formula to determine your daily iron needs:

Iron Requirement (mg/day) = Base Requirement + Activity Adjustment + Special Condition Adjustment

The base requirement is determined by age and gender according to the table above. The activity adjustment increases the requirement by 20% for moderately active individuals and 30% for active individuals. Special conditions (pregnancy, breastfeeding) have their own specific requirements.

Example Calculation

Let's calculate the iron needs for a 30-year-old moderately active female who is not pregnant or breastfeeding:

Base requirement: 18 mg/day (from the table)
Activity adjustment: 20% of 18 mg = 3.6 mg
Total requirement: 18 + 3.6 = 21.6 mg/day

Therefore, this individual should consume approximately 22 mg of iron per day.
