Iron absorption from tablets is actually quite poor. High dose iron supplementation just tends to cause more side effects (constipation, abdominal discomfort) without a significant improvement in iron levels and subsequent rise in haemoglobin levels.
Vitamin C helps improve absorption and the tannins in tea makes it worse. Generally taking Fe supplements with food is better than on an empty stomach.
Often with profound Fe deficiency giving the iron as an IV infusion is more effective at gaining a boost in Hb levels.
