What is an additional function of Vitamin C besides connective tissue formation?

Vitamin C, also known as ascorbic acid, is widely recognized for its role in the formation of connective tissues, such as collagen, but it also plays a significant role in immune function. As an essential nutrient, Vitamin C contributes to the immune system by enhancing the function of various immune cells. It aids in the proliferation of lymphocytes, which are crucial for the adaptive immune response, and it enhances the activity of phagocytes, which are responsible for engulfing and destroying pathogens.

Additionally, Vitamin C acts as a powerful antioxidant, helping to protect immune cells from oxidative stress and damage, which can occur during infections. This antioxidant property also supports the overall health and effectiveness of the immune response. By improving cellular function and protecting against oxidative damage, Vitamin C helps the body fend off illnesses more effectively.

In contrast, the other options do not directly link to Vitamin C's well-established roles. Bone mineralization is largely influenced by minerals like calcium and phosphorus, visual acuity depends on various nutrients, including Vitamin A, and nerve signal transmission primarily involves neurotransmitters and other specific nutrients related to nerve health, rather than Vitamin C alone.
