Which beverage is most likely to enhance iron absorption when taken with iron supplements?

• A. Milk
• B. Orange juice
• C. Coffee
• D. Tea

Answer: (B)

Maximizing absorption of non-heme iron depends on keeping iron dissolved and available for transport in the gut, and vitamin C is the key helper. Orange juice provides a good dose of vitamin C, which reduces ferric iron to the more absorbable ferrous form and forms a soluble iron-ascorbate complex that stays dissolved in the intestinal environment. This dramatically improves how much iron the body can take up from supplements.

Be mindful of beverages that blunt iron absorption. Milk brings calcium, which competes with iron for absorption in the gut, lowering uptake. Coffee and tea contain polyphenols and tannins that bind iron and form insoluble complexes, also reducing absorption. So, pairing iron supplements with orange juice (a vitamin C-rich drink) is preferred, while avoiding milk, coffee, or tea at the same time. If GI upset is an issue, you can still take iron with vitamin C-based fluids, but try to separate it from calcium- and tannin-containing beverages.
