Which vitamin is primarily associated with aiding in iron absorption?

Vitamin C is primarily associated with aiding in iron absorption due to its ability to convert iron from its ferric form (Fe³⁺) to its more absorbable ferrous form (Fe²⁺) in the digestive tract. This conversion is important because the ferrous form is much easier for the body to absorb. Furthermore, vitamin C can form complexes with iron, which also enhances its solubility and absorption in the intestines.

This relationship is particularly significant for non-heme iron, which is the type of iron found in plant-based foods and supplements. A meal rich in both vitamin C and non-heme iron can significantly increase the amount of iron the body can utilize, making it particularly important for individuals at risk of iron deficiency.
