Does iron give you energy?
Iron is one of the essential vitamins to take for energy. It is mainly found in your red blood cells as Hemoglobin. Your body uses iron to hold on to oxygen in your blood and transport it to your tissues. At the cellular level, iron is used then to make energy and to fuel enzymes.
What is iron in food?
Iron is a mineral that is naturally present in many foods, added to some food products, and available as a dietary supplement. Iron is an essential component of hemoglobin, an erythrocyte (red blood cell) protein that transfers oxygen from the lungs to the tissues [ 1 ]. As a component of myoglobin, another protein that provides oxygen, iron supports muscle metabolism and healthy connective tissue [ 2 ]. Iron is also necessary for physical growth, neurological development, cellular functioning, and synthesis of some hormones [ 2, 3 ].
What are the two main forms of iron?
Dietary iron has two main forms: heme and nonheme [1]. Plants and iron-fortified foods contain nonheme iron only, whereas meat, seafood, and poultry contain both heme and nonheme iron [2]. Heme iron, which is formed when iron combines with protoporphyrin IX, contributes about 10% to 15% of total iron intakes in western populations [3-5].
What is the richest source of iron?
Food. The richest sources of heme iron in the diet include lean meat and seafood [ 19 ]. Dietary sources of nonheme iron include nuts, beans, vegetables, and fortified grain products. In the United States, about half of dietary iron comes from bread, cereal, and other grain products [ 2, 3, 5 ].
Why are infants at risk for iron deficiency?
Infants—especially those born preterm or with low birthweight or whose mothers have iron deficiency—are at risk of iron deficiency because of their high iron requirements due to their rapid growth [ 34, 45 ]. Full-term infants usually have sufficient iron stores and need little if any iron from external sources until they are 4 to 6 months old [ 2 ]. However, full-term infants have a risk of becoming iron deficient at 6 to 9 months unless they obtain adequate amounts of solid foods that are rich in bioavailable iron or iron-fortified formula.
What is the term for a depleted iron store?
Iron deficiency progresses from depletion of iron stores (mild iron deficiency), to iron-deficiency erythropoiesis (erythrocyte production), and finally to iron deficiency anemia (IDA) [8,9]. With iron-deficiency erythropoiesis (also known as marginal iron deficiency), iron stores are depleted and transferrin saturation declines, but hemoglobin levels are usually within the normal range. IDA is characterized by low hemoglobin concentrations, and decreases in hematocrit (the proportion of red blood cells in blood by volume) and mean corpuscular volume (a measure of erythrocyte size) [2,10].
Why is iron deficiency a risk factor for gastrointestinal disorders?
People with certain gastrointestinal disorders (such as celiac disease, ulcerative colitis, and Crohn’s disease) or who have undergone certain gastrointestinal surgical procedures (such as gastrectomy or intestinal resection) have an increased risk of iron deficiency because their disorder or surgery requires dietary restrictions or results in iron malabsorption or blood loss in the gastrointestinal tract [ 55-57 ]. The combination of low iron intake and high iron loss can lead to a negative iron balance; reduced production of hemoglobin; or microcytic, hypochromic anemia [ 58 ].
How much iron is in ferrous fumarate?
For example, ferrous fumarate is 33% elemental iron by weight, whereas ferrous sulfate is 20% and ferrous gluconate is 12% elemental iron [ 27 ]. Fortunately, elemental iron is listed in the Supplement Facts panel, so consumers do not need to calculate the amount of iron supplied by various forms of iron supplements.
Our Iron-Rich History
Iron minerals played a major role in our history. After the Bronze Age came the Iron Age. Iron also plays an important role in our health. We are red-blooded thanks to the atoms of iron in every red blood cell. It grabs oxygen, carries it where needed, and releases it. Without it, we would be anemic and die.
Understanding Magnets and Magnetic Force
We know that for a magnet to work things must line up internally. The “things” are electrons, which have to spin in the same direction creating a north-south influence. This is why nails, or needles, become magnetized from electricity, which flows in one direction.
Forming a Mineral
All elements are composed of protons and electrons. Forming a mineral requires an element acting as a metal, called a cation, which gives up its electrons to form a mineral. Iron does this and is positively charged as a result.
What are Iron Minerals? - Magnetite
Most mineral collectors are familiar with minerals centered on iron-like magnetite, a natural magnet. Magnetite tends to be black in color, lustrous and is found in many locations. Its crystals are cubic in the isometric system, but cubes are not common. It more often develops in octahedrons and less often in 12-sided dodecahedrons.
What are Iron Minerals? - Lodestone
During the second century BCE, early people were naturally curious about lodestone because of its magnetic property. In China, they found that if they floated a lodestone needle on water it would indicate direction. A liquid “compass” wasn’t used on a ship, but if the needle was suspended in air, it would indicate direction.
Why is iron toxic?
Toxicity is rare because the body regulates iron absorption and will absorb less if iron stores are adequate. [2] Excessive iron occurs most often from taking high-dosage supplements when not needed or from having a genetic condition that stores too much iron.
How does iron deficiency occur?
If this does not resolve, the next stage is a greater depletion of iron stores and a drop in red blood cells. Eventually this leads to iron-deficiency anemia (IDA) where iron stores are used up and there is significant loss of total red blood cells. Typically, a doctor screens for anemia by first checking a complete blood count (including hemoglobin, hematocrit, and other factors that measure red blood cell volume and size). If this is below normal, ferritin and transferrin levels may be measured to determine if the type of anemia is IDA (there are other forms of anemia not caused specifically by an iron deficiency). All of these measures would decrease with IDA.
How much iron is in cereal?
Some cereals and multivitamin/mineral supplements are fortified with 100% of the RDA for women for iron (18 mg). Over-the-counter high-dosage iron supplements prescribed for those with iron-deficiency anemia or who are at high risk for it may contain 65 mg or more.
