What is the primary role of Vitamin C?

Vitamin C primarily functions in collagen synthesis and exhibits antioxidant activity. Collagen is a crucial protein that provides structural support to various tissues in the body, including skin, blood vessels, and bones. Vitamin C is essential for the hydroxylation of proline and lysine residues in collagen, a process that enhances collagen's stability and strength.

Additionally, Vitamin C acts as a powerful antioxidant, protecting cells from damage caused by free radicals. This antioxidant property is important for maintaining overall health and preventing chronic diseases. By scavenging free radicals, Vitamin C helps mitigate oxidative stress and supports the immune system, further reinforcing its critical role in health and wellness.

The other choices relate to functions that are not primarily associated with Vitamin C. For example, energy production involves B vitamins, calcium absorption is related to Vitamin D, and hormone production is typically linked to various other vitamins and minerals.
