What is one major benefit of vitamin C regarding iron?

1. It replaces iron in the body

2. It decreases iron absorption

3. It helps in absorption of iron

4. It eliminates the need for iron

The correct answer is: It helps in absorption of iron

Vitamin C is known for its significant role in enhancing the absorption of non-heme iron, which is the type of iron primarily found in plant-based foods. This is particularly important for individuals who rely on these sources for their iron intake, such as vegetarians or those with dietary restrictions. When vitamin C is consumed alongside iron-rich foods, it reduces the iron from its ferric form to a more soluble ferrous form in the digestive tract. This conversion increases the bioavailability of iron, making it easier for the body to absorb. In contrast, options suggesting that vitamin C replaces, decreases, or eliminates the need for iron misrepresent its function. Vitamin C does not serve as a substitute for iron, nor does it decrease iron absorption; in fact, it actively facilitates the process.
