Which nutrient enhances iron absorption when consumed with iron-rich foods?

Explanation:
Vitamin C enhances iron absorption when consumed with iron-rich foods. It acts as a reducing agent, converting ferric iron to ferrous iron and helping form a soluble iron-ascorbate complex that is more easily absorbed in the small intestine, especially for non-heme iron found in plant foods. Pairing iron-rich meals with vitamin C–rich foods like citrus, tomatoes, or peppers can significantly boost uptake. In contrast, calcium can interfere with iron absorption when taken together, vitamin D doesn’t notably affect iron absorption, and potassium has no major impact.
