Vitamin C may help to support immunity by encouraging healthy white blood cell activity and normal function. This is especially true for important immune B-cells (B-lymphocytes), which are critical when the body is challenged by harmful bacteria and viruses. Vitamin C not only protects against free radicals that can damage the cells in our body but goes one step further by helping to recharge other antioxidants. Another area where Vitamin C may play an important role is in the support of collagen growth and health. Collagen is the protein that provides the basic structure and function of tissues such as skin, ligaments, tendons, blood vessels, and cartilage. Vitamin C is essential to collagen’s optimal function. The prevalence of Vitamin C in the diet varies widely depending on how many fresh fruits and vegetables are eaten. That’s why taking a Vitamin C supplement may provide some extra assurance that you are getting enough of this critical nutrient.
