What is the function of vitamin C in the body?

Vitamin C plays a crucial role in various bodily functions, notably in supporting the immune system and aiding in collagen production. This water-soluble vitamin is essential for the synthesis of collagen, which is a vital protein in the body that helps maintain the structure of skin, blood vessels, bones, and connective tissues. By promoting collagen production, vitamin C helps in the healing of wounds and the maintenance of skin integrity.

Additionally, vitamin C is known for its antioxidant properties, which help protect the body against oxidative stress and support overall immune function. It enhances the body’s ability to fight infections, making it important for a healthy immune response.

In contrast, the other options do not accurately reflect the established roles of vitamin C in the body. Increasing blood pressure is not a function of vitamin C; rather, the vitamin has been studied for its potential to lower blood pressure in some contexts. Enhancing muscle growth is primarily influenced by nutrients like protein and exercise rather than vitamin C. Lastly, while vitamin C may play a secondary role in metabolism, it is not directly involved in reducing fat storage. Thus, the supportive role of vitamin C in immune health and collagen formation is well-documented, making this answer the most accurate.
