Iron Deficiency and Fatigue: How to Restore Your Energy
If you feel tired no matter how much you rest, iron may be the missing piece. Iron deficiency is the most common nutritional deficiency in the world and a leading cause of fatigue — especially in women, children and people with restricted diets.
Signs of low iron
- Persistent tiredness and weakness
- Pale skin, brittle nails or hair shedding
- Breathlessness, dizziness or headaches
- Poor concentration and low mood
Why the form of iron matters
Traditional iron supplements are notorious for causing constipation and stomach upset, which puts people off taking them. Gentler, highly absorbable forms such as iron bisglycinate are much easier on the stomach while still restoring iron levels — and pairing iron with vitamin C improves absorption.
A complete energy formula
Iron works best alongside B-vitamins, zinc and other nutrients involved in energy and blood health. A balanced multivitamin-and-mineral tonic can restore energy while supporting appetite, immunity and overall vitality. Confirm significant deficiency with a blood test where possible.
