What substance can enhance iron absorption when consumed together?

Ascorbic acid, commonly known as Vitamin C, plays a significant role in enhancing iron absorption, particularly non-heme iron, which is the type of iron found in plant-based foods and supplements. When consumed alongside iron-rich foods or iron supplements, Vitamin C helps convert iron into a more soluble form, increasing its bioavailability in the digestive system. This action is particularly beneficial for individuals who may be at risk of iron deficiency, as it allows for better utilization of the iron consumed in the diet.

In contrast, substances like calcium can interfere with iron absorption when taken in high amounts. Vitamin B12 and magnesium, although important nutrients in their own rights, do not have a direct impact on the absorption of iron. Understanding these interactions is key for individuals who are aiming to optimize their iron intake, particularly for pregnant women and those with specific dietary restrictions.
