Iron Requirement Calculator
Calculate daily iron needs
About this calculator
The Iron Requirement Calculator helps determine your daily iron needs based on age, gender, life stage, and dietary preferences. Iron is essential for oxygen transport, energy production, and immune function, yet deficiency affects millions worldwide. This tool provides personalized recommendations following established nutritional guidelines, helping you maintain optimal iron levels through proper dietary planning and supplementation when necessary.
How to use
Enter your age, select your gender, and indicate if you're pregnant or breastfeeding. Choose whether you follow a vegetarian diet, as plant-based iron has different absorption rates. The calculator will instantly display your recommended daily iron intake in milligrams based on current dietary guidelines.
Frequently asked questions
Why do women need more iron than men?
Women require more iron due to menstrual blood loss, which depletes iron stores monthly. This increases their daily iron needs significantly compared to men.
Do vegetarians need more iron?
Yes, vegetarians need about 1.8 times more iron because plant-based iron (non-heme) is less easily absorbed than iron from meat sources.
When should I take iron supplements?
Take iron supplements when dietary intake is insufficient or if diagnosed with iron deficiency. Always consult a healthcare provider before starting supplementation.
