Iron (Fe) is an essential trace mineral critical for life, playing a central role in the formation of hemoglobin - the protein in red blood cells responsible for carrying oxygen from the lungs to every tissue in the body. Beyond oxygen transport, iron is a component of myoglobin (supplying oxygen to muscles) and is required for cellular energy production, DNA synthesis, physical growth, and neurological development.
Iron deficiency is the most common nutritional deficiency globally, particularly affecting women of childbearing age, pregnant women, and vegetarians, often leading to Iron Deficiency Anemia (IDA).

Benefits of Iron
 
Adequate iron intake is fundamental to maintaining high energy levels, optimal immune function, and overall vitality.
​
Key Benefits
​
a) Increased Energy and Reduced Fatigue: By supporting optimal oxygen delivery to tissues and the brain, iron is key to preventing the extreme fatigue and weakness characteristic of anemia.

b) Cognitive Function: Iron is necessary for neurological development and supports brain functions like focus, memory, and concentration. Low levels are associated with reduced mental performance.

c) Immune System Support: Iron is required for the proliferation and maturation of immune cells, helping the body mount an effective defense against pathogens.

d) Healthy Pregnancy: Essential for the dramatic increase in maternal blood volume and for meeting the high iron demands of the growing fetus and placenta.

e) Physical Performance: Supports muscle metabolism and oxygen supply to muscles, improving athletic stamina and physical work capacity.

Mechanism of Action
​
Iron's functions are based on its ability to transition between its two primary redox states - ferrous (Fe2+) and ferric (Fe3+):

a) Oxygen Binding: The most crucial function is providing the binding site within the Heme group of the hemoglobin protein. In the lungs, the iron atom binds to oxygen molecules, transporting them through the bloodstream for release in tissues.
 
b) Cellular Respiration: Iron is a cofactor for enzymes involved in the electron transport chain within the cell's mitochondria, the primary site of ATP (energy) production.
 
c) Absorption and Regulation: Iron is absorbed primarily in the small intestine. The body carefully regulates iron levels using the hormone hepcidin, which prevents iron overload by inhibiting the release of stored iron when levels are high.

Related Statistics (RDA and Deficiency)
​
a) Recommended Dietary Allowance (RDA) for Adults:
Men (19+ yrs): 8 mg/day.
Women (19–50 yrs): 18 mg/day (due to menstrual blood loss).
Pregnant Women: 27 mg/day (highest requirement).

b) Global Impact: Iron deficiency is the most prevalent nutritional disorder worldwide, affecting an estimated 30–40% of women and causing over half of all anemia cases globally.
 
Signs of Iron Deficiency
​
Iron deficiency progresses through stages, starting with depleted iron stores (ferritin) before progressing to full-blown Iron Deficiency Anemia (IDA).

a) Extreme Fatigue and Weakness: The most common symptom, caused by poor oxygen delivery.
b) Pallor (Pale Skin): Noticeable paleness, especially on the inner eyelids and under the fingernails, due to low hemoglobin concentration.
c) Shortness of Breath (Dyspnea): Occurs especially during exertion, as the body struggles to meet oxygen demand.
d) Headaches and Dizziness: Resulting from insufficient oxygen supply to the brain.
e) Pica: A strong, unusual craving for non-food items like ice, clay, or dirt.
f) Restless Legs Syndrome (RLS): Low iron is a common contributing factor to RLS.
g) Koilonychia: Spoon-shaped or brittle fingernails. 
 
Sourcing Innovation: Ferrochel® Iron Bisglycinate
​
While the general term is Ferrous Bisglycinate Chelate, the specific, patented form produced by Albion Minerals is trademarked as Ferrochel®. This ingredient is widely recognized as a gold standard in modern iron supplementation due to its superior absorption profile and excellent tolerance.

Why Ferrochel® is Superior:

a) Chelation for Protection: In Ferrochel®, the ferrous (Fe2+) iron ion is chemically bonded (chelated) to two molecules of the amino acid Glycine. This creates a small, stable, and electrically neutral molecule that is protected from breaking down in the harsh environment of the stomach.

b) Bypassing Inhibitors: Because the chelate remains intact, the iron avoids direct contact with the intestinal lining and bypasses many common absorption inhibitors found in food (like phytates in grains and polyphenols in tea/coffee). Clinical studies have shown that absorption from Ferrochel® can be 2 to 3 times greater than traditional Ferrous Sulfate.

c) Maximum Tolerance: The protective Glycine shell prevents the free iron from irritating the digestive tract.This significantly reduces the incidence of common side effects associated with traditional iron salts, such as:
Nausea
Stomach Cramping
Constipation
 

In essence, Ferrochel® leverages the body's affinity for amino acids, allowing the iron to be absorbed more like a peptide than a mineral, leading to higher efficacy and better compliance.

​Forms and Bioavailability
​
Iron exists in two main dietary forms, with supplements offering varying degrees of elemental iron and bioavailability. The Fe2+ (ferrous) forms are generally better absorbed than Fe3+ (ferric) forms but often cause more side effects.

Important Note:
Vitamin C (Ascorbic Acid) enhances the absorption of non-heme iron by keeping it in the easily absorbed Fe2+ state.

Natural Food Sources
 
Dietary iron is classified into two types: Heme (highly absorbed) and Non-Heme (less efficiently absorbed).

a) Heme Iron (Best Absorbed): Found exclusively in animal products.

- Red Meat: Beef, lamb, and venison.
- Organ Meats: Liver (one of the richest sources).
- Shellfish: Oysters, clams, and mussels.

b) Non-Heme Iron (Less Absorbed): Found in plant foods and fortified products.

- Legumes: Lentils, beans, and chickpeas.
- Greens: Spinach, kale, and collard greens.
- Nuts and Seeds: Pumpkin seeds, sesame seeds.
- Fortified Foods: Breakfast cereals, bread, and some plant milks.

Absorption Inhibitors: Phytates (in grains/beans), polyphenols (in tea/coffee), and calcium can significantly reduce the absorption of non-heme iron.
 
Regulatory Status and Market Trends​
​
​Regulatory Status:
Iron is regulated as a Dietary Supplement and is an over-the-counter treatment for iron deficiency. Due to the toxicity risk of overdose (especially in children), the FDA requires strict warnings on iron supplements. High-dose oral and intravenous iron treatments are available as prescription drugs for severe anemia.

Market Trends:
The oral iron supplement market is expanding, driven by better-tolerated formulations:

a) Focus on Tolerance: Strong shift away from older iron salts (like Ferrous Sulfate) toward chelated forms like Ferrous Bisglycinate and Heme Iron Polypeptide due to reduced GI side effects, which improves patient compliance.

b) High-Risk Groups: Sustained high demand among women of childbearing age, pregnant women, and the increasing vegetarian/vegan population.

c) Advanced Delivery: Growth in liquid, liposomal, and powder forms that may offer better absorption or palatability, particularly for children and those with absorption issues.

 
​​Sourcing and Quality Considerations
​
Selecting a quality iron supplement is crucial for achieving therapeutic benefits without significant GI distress.

a) Form for Tolerance: If you have a sensitive stomach, choose a Chelated form like Ferrous Bisglycinate (e.g., Ferrochel®) or Heme Iron Polypeptide for superior gastrointestinal tolerance and proven high absorption.

b) Elemental Iron: Always check the label for the amount of Elemental Iron per dose, not just the total weight of the iron compound.

c) Combination: Look for formulas that include Vitamin C (Ascorbic Acid), as it significantly boosts the absorption of non-heme iron.

d) Caution: Iron overdose can be toxic, especially for children. Keep supplements safely stored, and do not exceed the recommended dose without consulting a healthcare provider.

Frequently Asked Questions (FAQs)
​
Why do iron supplements cause stomach upset or constipation?

Most traditional iron salts (Ferrous Sulfate, Ferrous Fumarate) are highly reactive and are not completely absorbed. The unabsorbed iron irritates the intestinal lining, leading to common side effects like constipation, nausea, and dark stools. Chelated forms like Ferrous Bisglycinate are better tolerated because they are absorbed more efficiently.

What should I take with iron to maximize absorption?

To maximize absorption of non-heme iron, take your supplement with a source of Vitamin C (Ascorbic Acid), such as a glass of orange juice or a Vitamin C supplement. You should avoid taking iron with coffee, tea, or calcium-rich foods (like milk or cheese) as these can significantly inhibit absorption.

Who is most at risk for Iron Deficiency Anemia (IDA)?

The highest risk groups are women of childbearing age (due to heavy menstrual bleeding), pregnant women (due to high fetal demands), vegetarians and vegans (due to poor absorption of non-heme iron), and individuals with gastrointestinal conditions (like IBD or Celiac disease) that impair absorption.

What is the difference between Ferritin and Hemoglobin?

Hemoglobin is the protein in red blood cells that carries oxygen. Ferritin is the protein that stores iron in the body (primarily in the liver). A low ferritin level is the earliest sign of iron deficiency, indicating that the body’s iron stores are depleted, even before anemia has fully developed.
