What nutrient is vital for healing and immune function, particularly in individuals with malnutrition?

Vitamin C is vital for healing and immune function, particularly in individuals with malnutrition, for several key reasons. One of its primary roles in the body is its involvement in collagen synthesis, which is essential for the formation of connective tissues, skin, and blood vessels. This makes vitamin C critical for wound healing, as it helps repair tissue that has been damaged.

Additionally, vitamin C functions as a powerful antioxidant, protecting cells from damage by free radicals, which can be more prevalent in those with compromised nutritional status. This antioxidant capacity is particularly important for boosting the immune response, as vitamin C supports various cellular functions needed for both the innate and adaptive immune systems. It aids in the production of white blood cells, enhances the skin's barrier function, and has anti-inflammatory properties that can help in recovery processes.

In individuals with malnutrition, the need for adequate levels of vitamin C becomes even more pronounced since their bodies may already be in a compromised state, increasing the risk for infections and slow healing. Ensuring sufficient vitamin C intake can significantly enhance healing processes and improve overall immune function in these individuals.
