Best Vitamin C Supplement for Immune System 2022
Vitamin C is an essential nutrient that humans cannot produce or store, which is why you need daily vitamin C for continued health. Vitamin C may be one of the most well-known immune nutrients that protect against immune deficiencies and which supports the prevention and recovery from the common cold and upper-respiratory issues, and also protects your cardiovascular system, eyes, skin, and other parts of your body.
Vitamin C supports epithelial barrier function against pathogens and promotes the oxidant scavenging activity of the skin, thereby potentially protecting against environmental oxidative stress. Vitamin C accumulates in phagocytic cells, such as neutrophils, and can enhance chemotaxis, phagocytosis, generation of reactive oxygen species, and ultimately microbial killing.
Vitamin C deficiency results in impaired immunity and higher susceptibility to infections. (Source)
