🧠 Iron makes the brains messenger's
Iron is essential for making some of your brain's most important chemical messengers (neurotransmitters), including:
✨ Dopamine – supports motivation, focus, memory, and movement
😌 Serotonin – helps regulate mood, emotional wellbeing, and appetite
🌙 Melatonin – helps control your sleep-wake cycle and promotes restful sleep.
When iron levels are low, your body may struggle to produce these neurotransmitters efficiently. This can contribute to symptoms such as:
🔸 Fatigue and low energy
🔸 Brain fog and poor concentration
🔸 Low mood or increased anxiety
🔸 Restless sleep or insomnia
🔸 Reduced motivation
Iron deficiency doesn't always present as anaemia. Low iron stores (low ferritin) can sometimes affect how you feel long before your haemoglobin becomes abnormal.
If you're experiencing persistent fatigue, mood changes, or difficulty sleeping, it's worth discussing your symptoms with your healthcare provider. A thorough assessment, including appropriate blood tests, can help identify whether low iron may be contributing.
🌿 Your brain needs the right nutrients to function at its best—and iron is one of the key building blocks.
