Effect of Vitamin C on Iron Absorption

Completed · Not applicable

Conditions studied: Iron Deficiency

In brief

Iron deficiency is a common health problem worldwide. Ferrous fumarate (a form of iron) is often added to foods in an effort to prevent iron deficiency. Vitamin C can improve the amount of iron that the body absorbs, therefore it is often added to foods too. However, we don't know if vitamin C really increases the absorption of iron from ferrous fumarate. This study will measure the iron absorption in children from a meal containing some ferrous fumarate with and without vitamin C. The study will include 4 visits to the Children's Nutrition Research Center in Houston, TX.
