Question 20

Vitamin C is an antioxidant.

Vitamin C is known for its antioxidant properties, which help protect cells from damage caused by free radicals. This makes it an essential vitamin for overall health.

A) Vitamin D

Vitamin D is primarily known for its role in bone health and calcium absorption. It does not possess significant antioxidant properties like Vitamin C, thus making it an incorrect choice for the question.

B) Pyridoxine

Pyridoxine, also known as Vitamin B6, plays a crucial role in metabolism and the synthesis of neurotransmitters. However, it is not recognized as an antioxidant, which makes it an unsuitable option in this context.

C) Vitamin C

Vitamin C is a powerful antioxidant that helps neutralize free radicals in the body, thereby reducing oxidative stress and supporting the immune system. This characteristic is what qualifies it as the correct answer to the question.

D) Niacin

Niacin, or Vitamin B3, is important for energy production and DNA repair, but it does not function as an antioxidant. Therefore, it does not meet the criteria specified in the question.

Conclusion

Vitamin C stands out as the only option that serves as an antioxidant, effectively protecting the body from oxidative stress. In contrast, Vitamin D, Pyridoxine, and Niacin do not exhibit antioxidant properties, making them incorrect choices. Thus, Vitamin C is definitively the right answer in identifying an OTC vitamin with antioxidant capabilities.
