About





            

                
Vitamin A supports mucosal barrier integrity in the respiratory and gastrointestinal tracts and regulates cell-mediated immunity, cytokine production, and lymphocyte trafficking to mucosal surfaces. Known as the 'anti-infective vitamin,' deficiency is strongly associated with increased susceptibility to infectious diseases.
