Which of the following is a true statement about vitamin C?

1. It can cause a deficiency leading to severe health issues

2. It improves the immune system

3. It decreases iron absorption

4. It has no significant health benefits

The correct answer is: It improves the immune system

Vitamin C, also known as ascorbic acid, is well-known for its role in supporting the immune system. This vitamin acts as an antioxidant, which helps protect cells from damage caused by free radicals. It is involved in various biological functions, including the synthesis of collagen, which is crucial for skin, blood vessels, and tissues, and also aids in the absorption of iron from plant-based sources. While vitamin C does have a role in improving immune function by enhancing various cellular functions of both the innate and adaptive immune systems, it is important to note that while it helps support immune health, it is not a cure-all for preventing infections. The other statements may present misleading information. For instance, while a deficiency in vitamin C can lead to health issues such as scurvy, it does not accurately represent the potential benefits of vitamin C. Similarly, vitamin C actually increases iron absorption rather than decreasing it, and it certainly has notable health benefits beyond what is captured in statements suggesting it lacks significant effects. Understanding the roles of vitamins and their contributions to overall health is essential for pharmacy technicians and healthcare providers in promoting public health and wellness.
