At what age does the iron requirement increase for males?

The age range of 14 to 18 is crucial for males because this period coincides with adolescence, a time characterized by rapid growth and development, which significantly increases the body's nutritional needs. Iron is particularly important during this time due to the increased demands for hemoglobin production to support growing muscle mass and expanding blood volume. Additionally, males may begin to experience growth spurts that further elevate their iron requirements.

During adolescence, males experience several physiological changes, including increased muscle development and changes in blood volume, both of which require adequate iron intake to support. Iron is also essential for cognitive function and overall development, making it crucial for maintaining energy levels and supporting physical and mental development during these formative years. Therefore, the increased iron requirement for males at ages 14-18 reflects both their growth needs and the physiological changes occurring during this critical period.
