Which statement about iron supplementation is correct?

• A. If tolerated, take the iron supplement on an empty stomach.
• B. Increase your intake of citrus fruits and juices.
• C. Take the iron supplement first thing in the morning to avoid gastrointestinal discomfort.
• D. Drink a glass of milk along with your iron supplement.

Answer: (A)

Iron is best absorbed when it’s taken on an empty stomach because there’s less interference from other nutrients and the iron is more soluble in the stomach’s acidic environment. If it’s tolerated, this approach maximizes absorption. It’s not ideal to take it with milk or dairy products, since calcium can bind iron and reduce its uptake. Taking it first thing in the morning to avoid discomfort isn’t reliable, because an empty stomach can actually worsen GI upset for many people. While vitamin C or citrus can help absorption, the most important principle is maximizing absorption by not sharing the stomach with other minerals, hence taking it on an empty stomach if you can tolerate it.
