Iron
Iron is a mineral that is vital for multiple functions of the body, some of which include;
- efficient production of energy
- transportation and storage of oxygen
- playing a role in brain function
- supporting the function of a healthy immune system
Almost a quarter of females have inadequate iron intakes, compared to only 3% of males1. Females aged 14-50 have higher iron requirements than their male counterparts, with even larger requirements during pregnancy2.

Iron can be found in beef, lamb, chicken, fish, green vegetables, legumes, nuts, seeds, grains & dried fruit. Plant-derived iron is often more difficult for the body to absorb and hence vegetarians & vegans are particularly susceptible to iron deficiency and may find supplementation beneficial.
A common symptom of iron deficiency is fatigue. As fatigue can be a symptom of many other health conditions, some of which are serious, it is important not to self-diagnose iron deficiency and instead. Seek advice from a healthcare professional.
