Iron and energy – understanding your body’s needs

Iron is vital for oxygen transport and energy. Manage fatigue through a balanced diet or iron supplements to support your long-term health.


Feeling tired, low on energy, or struggling to concentrate can often be linked to lifestyle factors such as stress or lack of sleep. However, in some cases, these symptoms may also be associated with insufficient iron levels.

Iron plays a vital role in supporting energy production and overall wellbeing, yet it is one of the most common nutrient deficiencies worldwide. Understanding its function in the body can help guide better nutritional choices and support long-term health.

What is iron and why is it important?

Iron is an essential mineral that contributes to the production of haemoglobin, a protein in red blood cells responsible for transporting oxygen throughout the body.

Oxygen is required by cells to produce energy. Without sufficient iron, this process may become less efficient, which can contribute to feelings of fatigue and reduced physical performance.

Signs that iron levels may be low

Low iron levels may present with a variety of symptoms, including:

  • Fatigue or low energy
  • Difficulty concentrating
  • Shortness of breath during physical activity
  • Pale skin

These symptoms can vary in severity and may develop gradually over time.

Who may be at risk?

Certain groups may have an increased risk of low iron levels:

  • Women of reproductive age
  • Individuals with restrictive diets
  • People with increased physical demands
  • Those with limited dietary intake of iron-rich foods

Dietary sources of iron

Iron can be obtained from a variety of foods, including:

Haem iron (more easily absorbed)

  • Red meat
  • Poultry
  • Fish

Non-haem iron

  • Spinach
  • Lentils
  • Beans
  • Fortified cereals

Combining plant-based iron sources with vitamin C-rich foods may help improve absorption.

Supporting healthy iron levels

Maintaining adequate iron levels involves:

  • Consuming a balanced diet
  • Ensuring proper nutrient absorption
  • Addressing individual dietary needs

Where Brunel fits in

Where dietary intake may be insufficient, iron supplementation may be considered as part of a broader nutritional approach.

Products such as Floradix® and Brunel Basics Iron Plus provide sources of iron that may assist in supporting daily nutritional requirements when used appropriately.

When to seek medical advice

If symptoms such as persistent fatigue or weakness occur, it is important to consult a healthcare professional for proper assessment and guidance.

Conclusion

Iron plays a fundamental role in supporting energy production and overall health. Maintaining adequate levels through diet and, where appropriate, supplementation may help support daily wellbeing.
