Iron

Discover why iron is an essential mineral for oxygen transport, energy production and overall health.

Iron is an essential mineral required for many important functions throughout the body. It is best known for its role in the production of haemoglobin, the protein in red blood cells that carries oxygen from the lungs to tissues throughout the body.

Because the body cannot produce iron, it must be obtained through the diet or nutritional supplements. Iron is naturally found in both animal and plant foods, although the form and absorption differ between these sources.

The Basics

Understanding Iron

What is Iron?

Iron is an essential trace mineral that contributes to normal oxygen transport, energy-yielding metabolism and the normal formation of red blood cells and haemoglobin. It is required by every cell in the body to support normal physiological function.

Heme & Non-Heme Iron

There are two main forms of dietary iron. Heme iron, found in animal foods such as meat and seafood, is generally absorbed more efficiently by the body. Non-heme iron, found in plant foods such as spinach, beans and lentils, is also an important source of iron but its absorption can vary. Vitamin C can help improve the absorption of non-heme iron.

Iron & Energy

Iron contributes to normal energy-yielding metabolism because it helps transport oxygen throughout the body. Adequate iron intake supports the delivery of oxygen to muscles and tissues, allowing cells to produce energy efficiently.

Common Questions

Frequently Asked Questions

What is iron?

Iron is an essential mineral that contributes to the normal formation of red blood cells and haemoglobin, normal oxygen transport throughout the body and normal energy-yielding metabolism.

What is the difference between heme and non-heme iron?

Heme iron is naturally found in animal foods and is generally absorbed more efficiently. Non-heme iron is found in plant foods and fortified foods, and its absorption can be improved when consumed alongside vitamin C-rich foods.

What foods naturally contain iron?

Iron is naturally found in red meat, poultry, seafood, beans, lentils, spinach, pumpkin seeds, fortified cereals and many leafy green vegetables.

Why is vitamin C often paired with iron?

Vitamin C helps improve the absorption of non-heme iron found in plant foods by converting it into a form that is more easily absorbed by the body.

Can you get too much iron?

Yes. While iron is essential, excessive iron intake can be harmful. Iron supplements should only be taken according to the recommended serving size or under the guidance of a healthcare professional.
