Does Vitamin A Help Iron?
Vitamin A is needed to mobilise iron, so if iron and vitamin A are both short, address both.[1]

Vitamin A is needed to mobilise iron[1]
Vitamin A appears to help move iron out of storage and into new red blood cells; where vitamin A is short, anemia responds less well to iron alone.
If iron is short and vitamin A is too, address both.

- Do Iron and Manganese Compete?They are linked: iron deficiency raises manganese absorption and can make manganese toxicity worse.
- Does Riboflavin (Vitamin B2) Help Iron?Riboflavin is needed to use iron, so check riboflavin sources such as dairy, eggs and fortified grains when iron is short.
- Do Coffee and Tea Block Iron Absorption?Coffee and tea can inhibit iron absorption: in a study in adults, coffee and tea drunk with a bread meal cut the iron absorbed from it.
- Do Whole Grains and Beans Block Iron?Phytate in grains and beans lowers non-heme iron absorption, but in a typical western diet the effect matters little for most people’s iron status.
- Does Soy Affect Iron Absorption?Soy protein lowers non-heme iron absorption, largely because of its phytate.
- Do Iron and Copper Work Together?Yes. Copper takes part in iron metabolism, and anemia is one effect of copper deficiency, which is uncommon.
