Natural Sources of Iron

Natural Sources of IronIron is needed in over 90 enzymes. It is necessary for transportation of oxygen to the body or production of energy. It is essential for growth – particularly during pregnancy, breastfeeding, the first 2 years of life and during adolescent growth. It is important for normal brain development and for a strong immunity.

The recommended daily intake for iron is 8mg/day for men and post-menopausal women, and 18mg per day for younger women.

The upper tolerable limit is 45mg per day, however to correct iron deficiency up to 200mg per day may be necessary.

Note

  • Iron comes in haem and non-haem sources.
  • Haem iron comes from animal protein sources i.e meat. It is more readily absorbed – 20-25 percent is absorbed.
  • Non-haem iron comes from grains, legumes and dark green leafy vegetables.
  • Fibre, phytic acid (in grains and legumes), egg, tea, coffee and other minerals (zinc & calcium) reduce iron absorption- particularly non-haem iron absorption.
  • Vitamin C enhances non-haem iron absorption by up to 60 percent.
