Reply to comment by Robbeee in If a human being is bleeding internally say in their mouth or stomach would they still have a risk of anemia? by Robbeee

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.

Me, a hospital pharmacist who spends his days checking Venofer bags (iron sucrose for laypeople): Meh, probably right

Absorption is actually better 30 minutes to 2 hours before food, not with food. If patients cannot tolerate the GI side effects they can take it with minimal food. But especially not with caffeine, milk, high calcium foods, or anything high in fiber.

You absolutely want to take the pills with orange juice, something high in vitamin c.

And although absorption percentage is low, the high dose of the pills means I absolutely see positive effects in terms of correcting anemias that outweigh the side effects.

And that is why we can't differenciate between taking Tardyferon and a GI bleed - the stool is black in euther case, and the tests for blood in stoll post a positive.
