According to (S. Beveridge et al., 2008) in their article Immune-enhancing role of vitamin C and zinc and effect on clinical conditions Vitamin C levels in plasma and white blood cells rapidly decrease during infections and stress.
Vitamin C supplementation enhances components of the human immune system such as anti-microbial and natural killer (NK) cell activities, lymphocyte proliferation, chemotaxis and delayed hypersensitivity.
Vitamin C contributes to the maintenance of the redox integrity of cells and thereby protects them from reactive oxygen species generated during the respiratory burst and inflammatory response.
Similarly, zinc deficiency affects cellular mediators of innate immunity such as phagocytosis, NK cell activity and generation of the oxidative burst. Hence, both nutrients play significant and complementary roles in immune function and modulation of body resistance to infectious agents, thereby reducing the risk, severity and duration of infectious diseases. and duration of infectious diseases. Deficiency of either of these essential nutrients impairs immunity, with vitamin C being crucial for cellular immunity A large number of randomized controlled intervention trials with intakes of 1 g of vitamin C and 30 mg of Zn have been conducted. These trials suggest that adequate intakes of vitamin C and Zn help improve symptoms and shorten the duration of respiratory tract infections, including common infections. symptoms and shorten the duration of respiratory tract infections, including the common cold. Natural defenses can only provide complete protection if the body has enough Zn.
