Iron deficiency is still the most common and widespread nutritional disorder in the world according to WHO. In a recent iron absorption study in adult women with low iron stores in our lab (publication under review), we found that 15 g of GOS given with an iron supplement in the form of iron fumarate acutely increased iron absorption when given with water and a bread based meal. The dose of 15 g of GOS was tolerated well by the participants. As a follow up to the study mentioned above, we want to investigate: 1) if acute iron absorption is affected by lower doses of GOS; 2) whether this acute effect occurs for other commonly used iron compounds as well, such as iron sulphate and iron phosphate; and 3) if there are potential interactions on absorption with other enhancers of iron absorption, such as vitamin c.
