What is a common function of vitamin C?

Vitamin C plays several important roles in the body, with one of its primary functions being the support of immune function. It is a powerful antioxidant that helps to protect cells from damage caused by free radicals and supports various cellular functions of both the innate and adaptive immune system. This vitamin is involved in the production and function of white blood cells, which are essential for fighting infections and diseases.

Additionally, vitamin C enhances the skin's barrier function, which is vital in preventing pathogen entry into the body. Its role in collagen synthesis also helps maintain the integrity of tissues, further contributing to immune defense. Because of these functions, adequate vitamin C intake is associated with a reduced risk of chronic diseases and overall enhanced immune health.
