Low on Iron? 5 Signs of Iron Deficiency and How to Replenish

Iron is essential for the production of haemoglobin — a protein in red blood cells that helps carry oxygen around your body. Without enough iron, your body literally struggles to fuel itself. That is why fatigue, brain fog, and shortness of breath are some of the first signs something might be running low.

Feeling more anxious or moody than usual? Research shows a link between iron deficiency and symptoms of anxiety, irritability, and even low mood — because iron supports neurotransmitter production.

Noticing thinning hair or increased shedding? These are subtle but telling signs. When iron is scarce, your body prioritises the essentials over hair growth.

To boost your iron naturally and effectively: include heme iron (red meat, poultry, fish) and plant sources (lentils, spinach, fortified cereals), and pair them with vitamin C to enhance absorption. A highly absorbable supplement like Lisofer 30 can help replenish levels gently and consistently.
