5. Decreased immune function.

Vitamin C deficiency can lead to a decrease in the chemotaxis and bactericidal function of leukocytes, a decrease in the synthesis of immune antibodies, a decrease in the antiviral ability to interfere with the transcription of viral mRNA and inhibit virus synthesis, and a susceptibility to colds and various infectious diseases.
