MAIN Health Vitamins & Minerals Iron

Iron, which is known as Fe on the periodic table, is an essential trace mineral for nearly all forms of life, humans included.

The human body requires Iron for the construction of several proteins in the blood, and it is also found in many proteins in the body, where it performs many different roles. Iron deficiency is a relatively common affliction, and often results in iron-deficiency anemia.

Iron-deficiency anemia is characterized by a low number of oxygen carrying cells in the blood stream. Because Iron is essential for the production of these cells, iron deficiency can limit their production, which in turn limits the amount of oxygen the blood can carry.
Pregnant women should be especially mindful of their iron levels, because increased stress put on the body by pregnancy increases the body's required iron levels. Women are also statistically more likely to be below the recommended dietary intake of iron, which puts them at an even greater risk of iron deficiency anemia.

While there are a few limited situations where iron supplementation can have health benefits, most scientific evidence suggests that excess iron is generally harmful for the human body. In one study, researchers found that diluting the amount of iron in the blood by donating blood once a year actually lowered the risk of cardiovascular & heart disease by an astonishing 86% in men. The researchers caution that people who donate blood also lead generally healthier lifestyles, so at least some of that 86% cannot be attributed to reduced iron levels.

Something else to consider with regard to iron is that the body has no effective way of getting rid of excess iron. Studies have found that iron can accumulate in the brain during the aging process, where it can accelerate the mind's age related deterioration.

Lastly, vitamin C significantly increases the body's iron absorption rate, so iron supplements and vitamin C supplements should never be taken simultaneously.

For those who do suffer from deficiency, iron is found in a large variety of meats and vegetables, however it is absorbed much more efficiently from meats.
