Vitamin C is an important nutrient that may be low or deficient when the body is burdened with disease.
Vitamin C deficiency is reported to occur more frequently in patients with chronic disease, major depression, in hospitalized patients, post-surgical patients, radiation to the gastrointestinal tract, history of malabsorption, treatment with chemotherapy having intestinal or mucosal side effects, slow wound healing, or infection.
Symptoms of vitamin C deficiency include fatigue, myalgia, loss of appetite, weakness, poor wound healing, and edema or swelling in the lower extremities (i.e. legs, thighs, feet).
Vitamin C has important roles in supporting the immune system and decreasing inflammation.
It is for some of the above reasons why vitamin C may improve quality of life and survival.
