Patients with rhinitis can take appropriate vitamin supplements. The following clinical analyses are available: 1. Patients with chronic rhinitis can take appropriate supplements of vitamin A and vitamin B. Relevant research data show that when patients lack vitamin A or vitamin B, the incidence of chronic rhinitis is appropriately increased. The above vitamins can reduce the chance of chronic rhinitis attacks. 2. Patients with allergic rhinitis or acute rhinitis can be properly supplemented with vitamin C and other related vitamins. These vitamins have antioxidant and bactericidal effects and can improve the defense function of the mucosal epithelium, which can prevent infection and reduce the possibility of recurrent acute rhinitis and allergic rhinitis in patients.3. Patients with dry rhinitis and frequent nasal bleeding can reduce nasal bleeding with appropriate clinical supplementation of vitamin K. It can also be supplemented with other multivitamins, which are helpful to patients.
