Top iron rich foods including heme and non-heme sources, iron absorption tips, and FAQs. Your complete 2025 guide to increasing iron levels naturally.
Why Iron Matters for Your Body
Iron is an essential mineral your body needs to:
Produce haemoglobin (for red blood cells)
Transport oxygen to organs and muscles
Support brain development and immunity
Prevent iron-deficiency anaemia
Low iron = low energy. That’s why a well-balanced diet rich in iron is non-negotiable.
Types of Iron in Food
There are two types of iron found in our diet:
1. Heme Iron
Found in animal-based foods
Absorbs easily in the body
Best for increasing iron levels quickly
Sources: Red meat, chicken, liver, fish, shellfish
2. Non-Heme Iron
Found in plant-based foods
Absorbs less efficiently, but still valuable
Needs Vitamin C to absorb better
