Which dietary guidance helps optimize iron absorption during pregnancy?

• A. Take iron with vitamin C-rich foods to enhance absorption.
• B. Take iron with dairy products to improve absorption.
• C. Take iron with coffee to increase absorption.
• D. Avoid all fruits while taking iron.

Answer: (C)

Iron absorption is strongly influenced by what you eat around the dose. Vitamin C helps the body absorb iron by converting it to a form that stays soluble in the gut, making uptake into the bloodstream more efficient. So pairing iron with vitamin C–rich foods or a glass of citrus juice around the time you take the supplement directly boosts absorption.

Conversely, dairy products contain calcium, and beverages like coffee can contain compounds that bind iron. These substances can form insoluble complexes with iron or compete for absorption, reducing how much iron gets absorbed.

In pregnancy, when iron needs are higher, the practical guidance is to take iron with vitamin C–rich foods or juice and avoid calcium-rich foods or caffeinated drinks at the same time as the iron dose. If GI upset occurs, taking iron with a small amount of food is acceptable, but try to keep the iron away from dairy or coffee for best absorption.
