Formula and Logic
The calculator starts with a base iron requirement: 18 mg for females and 8 mg for males, based on general dietary guidelines. It then applies multipliers for activity level (1.0 to 1.5) and goal (0.9 to 1.3) to estimate your total need. The recommended range is shown as 90-110% of the calculated value to account for individual variation.
Practical Notes
- Iron needs can vary based on health conditions, pregnancy, or training intensity—consult a doctor for personalized advice.
- During endurance training or muscle-building phases, iron requirements may increase due to higher red blood cell production.
- Common dietary sources include lean meats, beans, spinach, and fortified cereals; pair with vitamin C for better absorption.
- Women of childbearing age often need more iron; monitor levels if you experience fatigue or weakness.
