What is one of the functions of Vitamin C related to iron?

Vitamin C plays a significant role in the absorption of iron, particularly non-heme iron, which is found in plant-based sources. One of its primary functions is to act as a reducing agent, converting ferric iron (Fe³⁺), which is less soluble, into ferrous iron (Fe²⁺), which is more easily absorbed in the intestines. This conversion enhances the bioavailability of iron from dietary sources, helping to prevent iron deficiency, especially in individuals who may not get enough iron from their diet.

Moreover, Vitamin C can help enhance the absorption of non-heme iron when consumed in conjunction with iron-rich foods. For instance, consuming citrus fruits or juices alongside meals high in iron can significantly increase the amount of iron that the body absorbs. This synergistic effect demonstrates the importance of Vitamin C in optimizing iron uptake from the diet, thereby playing a crucial role in maintaining adequate iron levels in the body.
