Iron is an essential mineral needed to
transport oxygen to tissues. It is also
necessary for DNA repair and mitochondrial energy production. Insufficient iron can cause anemia and
symptoms of fatigue, pallor, hair loss, poor exercise tolerance, restless legs,
and poor cognitive development in children.
Too much iron can accumulate in tissues and cause oxidative stress (called
hemochromatosis).
Most iron comes from heme sources or animal protein. Because of this vegetarians are at
risk for deficiency as are people who limit red meat intake for health reasons. Others at risk
include women with heavy menstrual bleeding, athletes engaged in intense
endurance exercise, and people with impaired digestion and absorption. We encourage consuming iron-rich foods along
with Vitamin C to increase absorption.
How much do I need? The recommended daily allowance is 8mg for
men, 19mg for women, and 27mg during pregnancy.
Individualized intake should be based on lab results including your CBC
and ferritin. Often, we recommend around 40mg per day to correct
deficiencies. Cooking in cast-iron
skillets can also increase your intake – add
5mg per saucy, vitamin C-rich dish that you cook in cast iron.
