Iron: why we need it and when to pay attention to it
1 November 2026
Iron is involved in carrying oxygen and in the formation of red blood cells. We look at its role, who tends to need more and what to bear in mind.
Iron is a mineral we need only in small amounts, but it is essential. Without it, the body could not carry oxygen to every cell.
What iron does
These are some of the functions officially recognised in the European Union:
- Iron contributes to normal formation of red blood cells and haemoglobin.
- Iron contributes to normal oxygen transport in the body.
- Iron contributes to the reduction of tiredness and fatigue.
- Iron contributes to the normal function of the immune system.
- Iron contributes to normal cognitive function.
Who tends to need more
Iron requirements are not the same for everyone. They tend to be higher in:
- Women of childbearing age, because of menstrual losses.
- Teenagers, because of growth.
- Pregnancy, a stage in which needs increase and which should always be followed by a health professional.
- Vegetarian or vegan diets, because iron from plant sources is less well absorbed.
Before taking iron on your own
Tiredness has many causes. If you feel fatigue that does not go away, the first step is to talk to your doctor: a blood test is the way to know your levels. Taking iron when you do not need it brings no benefit and may not agree with you.
The form of iron matters too
Not all iron is the same: its chemical form affects how it is absorbed and how well it is tolerated. That is why FERROHELSE®, our iron food supplement, uses liposomal ferric pyrophosphate (30 mg per capsule), together with vitamin C (80 mg) and folic acid (200 µg). Vitamin C increases iron absorption, and folate contributes to normal blood formation.
Food supplements should not be used as a substitute for a varied and balanced diet and a healthy lifestyle. Your pharmacist can advise you on whether an iron supplement makes sense for you.
