Did you know that Vitamin C is the 4th leading nutrient deficiency in the United States? (Schleicher et al, 2009)
How does vitamin C affect immune function?
Vitamin C supports BOTH the innate and adaptive immune systems, and can both inhibit and activate different parts of the immune system (Carr, 2017).
- In conditions like asthma and bronchial hypersensitivity, vitamin C can inhibit excessive activation of the immune response (Shaik, BD et al 2015).
- Vitamin C is necessary for recycling spent neutrophils(a type of white blood cell), in order to prevent toxic debris accumulation and stimulating migration of neutrophils to the site of an infection.
- In addition to recycling and stimulating neutrophil migration, vitamin C also enhances functions of lymphocytes, macrophages, and mast cells. The reduction of reactive oxygen species benefits the immune system, and accelerates killing of unwanted microbes.
