- Do You Need Copper With Zinc?Zinc at 50 mg a day or more for weeks can interfere with copper absorption and lower copper status.
- Do Iron and Manganese Compete?They are linked: iron deficiency raises manganese absorption and can make manganese toxicity worse.
- Does Vitamin A Help Iron?Vitamin A is needed to mobilise iron, so if iron and vitamin A are both short, address both.
- 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.
