Xylitol Nasal Spray Prevents SARS-CoV-2 Infection

Xylitol is known to have anti-infective and anti-inflammatory properties and is used in XLEAR nasal spray and anti-infective chewing gum to prevent dental caries. Balmforth found that SARS-CoV-2 infection confirmed by serology was 71% lower with xylitol compared to placebo [36 cases (13.1%) Vs 97 cases (34.5%); odds ratio [OR] 0.29 (95% CI; 0.18–0.45), p < 0.0001]. Fewer clinical symptoms were also seen in the test group [57 cases (17.6%) vs 112 cases (34.6%); OR 0.40, (95% CI; 0.27–0.59), p < 0.0001]. No harmful effects were associated with xylitol. A smaller study of xylitol nasal spray in mild COVID-19 cases demonstrated that persistent loss of smell may be eliminated with xylitol nasal spray during the acute congestion phase.
