Question

Absorption of oral iron preparations can be facilitated by co-administering ___.

• A. calcium carbonate
• B. calcium phosphate
• C. ascorbic acid
• D. casein

Hint:

Ascorbic acid enhances iron absorption by maintaining iron in its absorbable ferrous state.

Answer 1

The Correct Option is C

Ascorbic acid (vitamin C) enhances the absorption of non-heme iron by reducing it to its ferrous form (Fe\(^{2+}\)), which is more readily absorbed in the intestine. Other substances like calcium compounds can actually inhibit iron absorption.
