Which of the following nutrients is important for iron metabolism?

• A. Vitamin C
• B. Folate
• C. Vitamin B12
• D. Calcium

Answer: (A)

Vitamin C plays a crucial role in iron metabolism, primarily by enhancing the absorption of non-heme iron, which is the type of iron found in plant-based foods and supplements. When vitamin C is consumed alongside iron, it can form a complex that keeps iron in a soluble form, making it more readily absorbed in the intestines. This interaction is particularly important for individuals who rely on non-heme iron sources, as they may have lower absorption rates compared to heme iron found in animal products. Other nutrients mentioned may also be involved in overall health and metabolism but do not have the same direct impact on iron absorption as vitamin C does. For instance, folate is essential for DNA and RNA synthesis and red blood cell formation, while vitamin B12 is vital for nerve function and the production of healthy red blood cells. Calcium, while necessary for bone health, can inhibit iron absorption when consumed in high amounts at the same time, making its relationship with iron metabolism more complex. Thus, vitamin C’s role as an enhancer of iron absorption makes it the most relevant nutrient for iron metabolism in this context.
