Essential mineral for oxygen transport and energy production.
How it works
Iron is a key component of haemoglobin and myoglobin, enabling oxygen transport. It also supports mitochondrial energy production.
Evidence-based uses
Only supplement if deficient. Fatigue is a key symptom of iron deficiency.
Clinical Evidence
Iron supplementation reduced fatigue by 47.7% in non-anaemic iron-deficient women compared to 28.8% for placebo.
Iron supplementation reduced subjective fatigue by 29% in women of reproductive age, regardless of baseline anaemia status. The effect was strongest in non-anaemic iron-deficient women.
Only supplement if deficient. Get tested first. Iron overload can be dangerous.
Clinical Evidence
