Iron is essential to support many functions in the human body. Iron is crucial in forming hemoglobin which supports oxygen transport around the body. In this blog, we will cover:


The signs that your iron supplements are working

It can be challenging to know if your iron supplements are working. It is essential to remember iron is present in the body in two ways. Iron is found in our liver as storage and transport, or circulating (as hemoglobin) in our blood. When our iron intake is low, our storage iron drops first, having lower iron reserves. It can take up to three months to replenish storage iron.

As tiredness or a lack of energy (fatigue) is commonly associated with a diet low in iron, it is likely to be the first change in your body that you notice when you take an iron supplement (2). If your iron supplement is working, you should notice an increase in energy levels; however, when this will occur varies from person to person, and is dependent on your levels of iron in storage and circulation.

When your iron supplement works, you should have more energy, better concentration, and a healthier immune system (3).

How do I know how much iron I need in my supplements?

Our daily requirement for iron depends on several factors. Women of child-bearing age have the highest need for iron with a daily requirement of 14.8mg, while men and post-menopausal women have a daily requirement of 8.7 mg (5).

It is important to ensure your supplement is giving you a sufficient amount of iron. Some people experience side effects, especially from higher-dose iron pills resulting from poor absorption. The unabsorbed iron becomes oxidized and causes gut irritation, resulting in side effects such as constipation and nausea.


Is your iron supplement working well for you?

If you are not getting enough iron from your diet alone, an iron supplement can help your iron levels. An iron supplement that is working well should be easy to take with no side effects, and you should have a noticeable increase in your energy levels.

When choosing an iron supplement, it is essential to choose one strong on absorption while also gentle on the stomach.
