There is enough iron in the human body to make one small nail. Compared to all other elements in the human body, iron makes up roughly 0.006%. On average, the body loses 1-2 milligrams of iron a day through sweat, urine, and menstrual cycles. Iron is replenished through food.
More about iron in the human body:
- The majority of iron is found in hemoglobin, the blood cells which transport oxygen to the rest of the body.
- Should more iron be needed, the body will naturally increase the amount that is absorbed.
- Without an iron-balancing system, the body can absorb too much iron that may then collect on organs and cause poor function.
